According to the law of mass action,what must be equal at equilibrium?

DNA

all I had to do was just think back to middle school when I learned that

In order for a cellular change to be inherited, this change must be present in the male gamete, or sperm or present in  the female gamete, the egg or ovum. This is due to the fact that a baby is created from the fusion of an egg and sperm. Therefore, choice 2,  the deletion of a single DNA base in a sperm cell of a trout, is the correct answer.  

If we think about it logically, cellular changes in other parts of body should not affect the next generation. For example, if mom has skin cancer, it does not mean at all  that the baby will have it as well.

Mass percentage is one way of representing the concentration of an element in a compound or a component in a mixture. To calculate percent by mass, you need to determine two things: the mass of just the element, and the molar mass of the whole compound. We calculate as follows:

.10 g NaCl / g NaCl + Water = ( 10.0 g NaCl + x ) / (10.0 g + 255 g + x )

x = 18.33 g NaCl needed

Answer: Liquid water can never go over the boiling tempurature because it will turn into steam. The heat is going into the water particles which converts the liquid into steam.

Explanation:

When liquid particles are heated, they move around faster and bump into each other, and destribute the heat around the liquid evenly. This process is called convection. As the particles move fast enough, they turn the liquid into a gas. This process is called evaporation. So the gas is now at a liquid boiling point tempurature, but it in a liquid form can never go higher from that tempurature without turning into a gas.

At boiling point, added energy converts liquid water to gas by breaking intermolecular forces, not raising the temperature.

The boiling point of water occurs when its vapor pressure equals the external pressure.

At standard atmospheric pressure, water boils at 100°C (212°F).

Heating water increases molecular kinetic energy, aiding in overcoming intermolecular forces.

Instead of raising the temperature further, added energy breaks intermolecular bonds, initiating vaporization.

Vaporization is the phase change from liquid to gas, driven by energy input.

The latent heat of vaporization for water is about 2260 J/g at 100°C.

During vaporization, temperature remains constant until all liquid converts to gas.

Once vaporization is complete, additional energy increases steam temperature.

Boiling water undergoes phase change without temperature increase until all liquid becomes gas.

Answer:

octahedral

Explanation:

Six bonding pairs around a central atom result in an octahedral. Hence, option D is correct.

Octahedral molecules contain six atoms bonded to the central atom and no lone electron pairs, making the steric number equal to six.

VSEPR theory was first coined by Gillespie and Nyhlom in 1957 as an improvement over the Sidgwick - Powell theory.

According to this theory, the shape of a molecule is determined by the number of electron pairs that surround the valence shell of the central atom in the molecule.  The electron pairs are positioned as far apart in space as possible to minimize the repulsion of electron pairs.

However, the presence of lone pairs distorts the shape anticipated for the molecule on the basis of VSEPR.

For a molecule having six electron pairs, an octahedral geometry is expected(electron domain geometry).

Hence, option D is correct.

no charge

this is because protons have a charge of 1+ and electrons have a charge of 1- so if there is an equal number of them, their charges cancel each other out and make the atom have a charge of 0, which means no charge

Answer: An atom with an equal number of electrons and protons has no charge

Explanation: The charge of an atom comes from the electrons and protons present. Electrons have a charge of 1- and protons have a charge of 1+. When the number of electrons and of protons are equal, an atom has no overall charge.

Explanation:

The molecular weight of NaCl is 58.5 g/mol. 737 g/58.5 g/mol = 12.6 mol. So, there are 12.6 moles of NaCl in the box.

Taking into account the definition of molar mass, 12.61 moles are in 737 grams of NaCl.

But first, the molar mass of a given substance is a physical property defined as the mass of one mole of a substance, which can be an element or a compound.

In a compound the molar mass is equal to the sum of the weight or atomic mass of its atoms multiplied by its quantity; that is, the molar mass of the elements of the compound must be added multiplied by the times they appear.

In this case, the atomic mass of the elements of the compound are:

Then the atomic mass of the compound NaCl is:

NaCl= 23 g/mole + 35.45 g/mole

NaCl= 58.45 g/mole

Then you can apply the following rule of three: if by definition of molar mass 58.45 grams of the compound are contained in 1 mole, 737 grams are contained in how many moles?

[tex]amount of moles=\frac{737 gramsx1 mole}{58.45 grams}[/tex]

amount of moles= 12.61 moles

In summary, 12.61 moles are in 737 grams of NaCl.

The soil would be almost infertile after all the magma and heat. It cannot grow crops and plants will not be able to survive. It becomes 'baked' and therefore is very hard to grow ANYTHING

However after a period of time, the soil can make use of volcanic nutrients and grow lush plants (but this is after a while)

After a volcanic eruption, it is nearly impossible for plant life to grow due to the poor soil is a false statement.

A volcanic eruption is when lava and gas are released from a volcano—sometimes explosively.

After a volcanic eruption,the soil in this region is rich because volcanic eruption deposits the necessary minerals, which are then weathered and broken down by rain. Once absorbed into the soil, they become a steady supply of nutrients for plant life.

ΔH = 468 kJ/mol.

Both answers come with three sig. fig. as in data in the question.

Final mass of the solution:

[tex]m = \text{Mass of Solution} = \text{Mass of Solute} + \text{Mass of Solvent} = 51.55 + 5.12 = 56.67\;\text{g}[/tex].

An increase in temperature by one degree celsius is the same as an increase in temperature by one degree Kelvin. Change in temperature:

[tex]\Delta T = \text{Final Temperature} - \text{Initial Temperature} = 49.8 - 24.5 = 25.3\;\text{K}[/tex].

Assume that the specific heat capacity of the NaOH solution is the same as the specific heat capacity of pure water:

[tex]c = 4.182\;\text{J}\cdot\text{g}^{-1}\cdot\text{K}^{-1}[/tex].

In other words, it takes 4.182 Joules of energy to raise the temperature of one gram of pure water by one degree Kelvin. Assume that so is the case for the NaOH solution.

Energy change:

[tex]Q = c\cdot m \cdot \Delta T = 4.182 \times 56.67 \times 25.3 = 5995.95\times 10^{3} \;\text{J} = 6.00\times 10^{3}\;\text{J}[/tex].

Refer to a periodic table for relative atomic mass:

Formula mass of NaOH:

[tex]M(\text{NaOH}) = 22.990 + 15.999 + 1.008 = 39.997\;\text{g}\cdot\text{mol}^{-1}[/tex].

How many moles of formula units in that 5.12 gram of NaOH?

[tex]\displaystyle n = \frac{m}{M} = \frac{5.12}{39.997} = 0.128010\;\text{mol}[/tex].

ΔH measures the energy change per mole of NaOH dissolved. Dissolving 5.12 grams or 0.128010 moles of NaOH releases [tex]5.99595\times 10^{3} \;\text{J}[/tex] of energy.

[tex]\displaystyle \Delta H = \frac{Q}{n} = \frac{5.99595\times 10^{3}\;\text{J}}{0.128010\;\text{mol}} = 4.68\times 10^{5}\;\text{J}\cdot\text{mol}^{-1} = 4.68\times 10^{2}\;\text{kJ}\cdot\text{mol}^{-1}[/tex].

To calculate q of the solution, use q = m × c × ΔT. To find ΔH in kJ/mol for the reaction, use ΔH = q / n.

To calculate q of the solution, we can use the equation: q = m × c × ΔT, where m is the mass of the water, c is the specific heat capacity of water, and ΔT is the change in temperature. The specific heat capacity of water is approximately 4.18 J/g°C. First, we need to calculate the mass of the water by subtracting the mass of NaOH from the total mass. Then, we can calculate q using the equation.

To find ΔH in kJ/mol for the reaction as it occurred in the calorimeter, we can use the equation: ΔH = q / n, where n is the number of moles of NaOH. First, we need to calculate the number of moles of NaOH by dividing the mass of NaOH by its molar mass. Then, we can calculate ΔH using the equation.

1) Everything is made up of atoms. 2)Atoms are indivisible and also undestroyable. 3) The combination of 2+ different kinds of atoms creates compounds 4) A chemical reaction happens when atoms are rearranged/moved around.

Dalton's atomic theory provides a basis for understanding matter at a microscopic level. This understanding aids in interpreting the differences in the three states of matter - solid, liquid, and gas. In these different states, atoms exhibit different degrees of freedom and arrangements.

The atomic theory of atoms was initially proposed by Dalton and it provides a microscopic understanding of the macroscopic properties of matter. According to Dalton's atomic theory, all matter is composed of small particles called atoms and each element has its unique type of atom. And crucially, atoms are neither created nor destroyed during a chemical change, which illustrates the principle of the law of conservation of matter.

This theory helps us understand the difference in the three states of matter (solid, liquid, and gas). In solids, atoms are tightly packed together, and have little freedom to move, resulting in a defined shape and volume. In liquids, atoms have more freedom to move but are still close together, resulting in a defined volume, but the shape of the liquid changes to fit its container. In gases, atoms have the most freedom to move and are farther apart, resulting in neither a defined shape nor volume.

all i really know is that STP (standard temperature and pressure) represents conventional conditions established by IUPAC with T = 273.15 K, P = 1 atm . Now putting these values of temperature and pressure at STP, we can calculate easily volume occupied by 1 mol of gas and which comes out to be 22.4 L. hope this helps

Answer:

Volume of the gas is 90.2 ml

Explanation:

Given:

Initial volume, V1 = 80.0 ml = 0.080 L

Initial pressure, P1 = 109 kPa = 1.076 atm ( 1 kPa = 0.00987 atm)

Initial temperature, T1 = -12.5 C = -12.5 + 273 K = 260.5 K

Under STP conditions i.e. standard temperature and pressure we have:

Pressure, P2 = 1 atm

Temperature, T2 = 273 K

Hope this helped!

Thrust faulting is a form of geological fault that occurs when one section of earth's crust is forced over another, causing rock layers to overlap and creating geological features like mountains. It's associated with the forces of tectonic plate interactions and plays a key role in understanding how the earth's surface has changed over time.

In the earth's crust, thrust faulting is a type of fault in geology that occurs when one slab of the earth's crust is forced up and over another. This movement results in layers of rock being pushed on top of each other, causing significant distortion and upheaval, as well as leading to the creation of various geologic features such as mountains. The process of thrust faulting is often associated with the powerful forces of tectonic plate interactions, particularly at convergent boundary areas where plates are pushing against each other. It's an essential concept in interpreting the earth's complex geological history as it contributes to our understanding of how our planet's surface has changed and evolved over many millions of years.
