The correct student would be student D since an ionic bond is made up of a metal and nonmetal where metals usually give electrons and nonmetals take.

Answer is: Student D: Assets of a small company being taken over by a large company.

Ionic bond is the electrostatic attraction between oppositely charged ions (cations and anions).

For example, compound magnesium chloride (MgCl₂) has ionic bond.

In this example, chlorine is large company, because it has greater electronegativity than magnesium (small company) and take electrons (assets) from it.

Magnesium (Mg) transfers two electrons, became positive cation, to chlorine (Cl), which became negative anion.  

Magnesium is metal from group 2 and chlorine is nonmetal from group 17 of the Periodic table.

Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.

The amount of electrons transferred depends on how many electrons an element gains/loses. Metals normally lose electrons and nonmetals gain electrons to attain a total of 8 electrons.

I would have to say A. FeCl2•4H2O

We have to get the true statement about Dalton's atomic theory.

The true statement is: Dalton’s theory recognized that all matter is composed of atoms.

According to Dalton's atomic theory, all matter is made of atoms and atoms are indivisible and not destructible. So, the statement -Dalton’s theory recognized that all matter is composed of atoms- is true whereas the statement - Dalton’s theory recognized the existence of smaller particles within atoms is false.

As per Dalton's theory, all atoms of a given elements are identical in mass and properties, so the statement -Dalton’s theory did not account for the similarities of atoms of the same element is false.

Also, compounds are formed by a combination of two or more different kinds of atoms hence the statement - Dalton’s theory stated that atoms could not combine with each other is false.

Answer:

evidence that some kinds of matter are made up of waves instead of particles

observations that cannot be explained by the theory

Explanation: these ones are right trust

M= Moles/ L

2.50=x/0.0150

x=0.0375 moles

moles x mm= grams

0.0375 x 247.8= 9.2925 grams

the answer is

Fossil fuels are still being widely used because of the fact that the demand for alternative fuels cannot be met by current manufacturers.

Answer:

cost-effective alternatives are not yet ready to replace fossil fuels; they are the cheapest resource, especially oil.

Answer:

Here we need to find the morality of 60 grams of NaOH dissolved in 750ml because the amount of solute is usually taken in ml and 750 litres is way to high.

So, coming towards the question, we need to find molarity.

As we know, molarity is no of moles of a substance per litre of the solution.

                                           Molarity= mole\volume ----> 1

Now we will change 750ml  to litres

                                      750/1000 = 0.75 litres

Now we need to find no of moles of NaOH.

As we know, no of moles = mass /molar mass

                       no of moles =60 grams / 40

                       no of moles= 1.5 moles

Putting the values of no of moles and volume in equation 1

                               Molarity= mole\volume ----> 1

                                             =1.5 moles/ 0.75 litres

                                             =2 M

So the answer will be 2 Molar.

Final answer:

Water is classified as a compound because it consists of hydrogen and oxygen atoms bonded in a fixed ratio, represented by the chemical formula H2O. Elements contain only one type of atom, and mixtures combine substances without forming new chemical bonds.

Explanation:

Water is a compound, not an element or a mixture. This is because it is composed of hydrogen and oxygen atoms in a fixed ratio. To be more precise, a water molecule consists of two hydrogen atoms bonded to one oxygen atom, which can be represented by the chemical formula H2O. Molecules of elements contain only one type of atom, whereas molecules of compounds, like water, contain two or more types of atoms bonded together in a specific geometric arrangement.

In contrast, a mixture is a combination of two or more substances that maintain their own chemical identities, and they do not bond chemically to form a new compound. For example, air is a mixture of nitrogen, oxygen, argon, and carbon dioxide, among other gases.

b2+ + 2 NO3- + 2 Na+ + 2 I- >> PbI2 (s) + 2 Na+ + 2 NO3-  

net ionic

Pb2+ + 2 I- >> PbI2  

Ksp = [Pb2+] [I-]^2  

Ksp = 7.1 x 10^-9  

molar solubility

let x = mol/L of Pb2+ that dissolve . This will give x mol/L Pb2+ and 2x mol/L I-  

7.1 x 10^-9 = (x) (2x)^2 = 4x^3  

molar solubility = 0.0012 M

the molecular formula of calcium oxide - CaO

The molar mass of CaO - 40 + 16 = 56 g/mol 

Which means that 1 mol weighs 56 g

Therefore 56 g of CaO is - 1 mol

Then 89.23 g is equivalent to - 1/56 x 89.23 = 1.6 mol of CaO.

Final answer:

To find the number of moles in 89.23 g of calcium oxide, divide the mass by the molar mass of CaO, which is 56.0 g/mol, resulting in approximately 1.5934 moles.

Explanation:

To calculate the number of moles equivalent to 89.23 grams of calcium oxide (CaO), one must use the molar mass of CaO as a conversion factor. The molar mass of CaO, where calcium (Ca) has an atomic mass of 40.0 u and oxygen (O) has an atomic mass of 16.0 u, is 40.0 g/mol + 16.0 g/mol = 56.0 g/mol.

The number of moles of CaO can be determined by dividing the given mass by the molar mass:

Number of moles of CaO = (mass of CaO) / (molar mass of CaO)
= 89.23 g / 56.0 g/mol
= 1.5934 moles

Therefore, 89.23 grams of calcium oxide are equal to approximately 1.5934 moles of CaO.

Answer: (c) a gold brick would have the least amount of inertia.

The inertia of an object refers to its ability to continue in its present state of rest or uniform motion until any external force act of the body to change its state of motion.

The inertia of a body increases with its mass. For this reason, a body with more mass and high inertia needs larger force to change its state of motion or rest. Among the given objects, the mass of a gold brick is the least. For this reason, it would have the least amount of inertia and least amount of force is required to change its state of motion or rest.

The chemical reaction is the process in which one or more reactants are converted into one or more than one product. The statement about chemical reactions is not true is new atoms are formed as products.

In a chemical reaction, one or more materials known as reactants are changed into one or more additional substances also known as products. Chemical elements or chemical compounds make up substances.

When one or more chemicals are transformed into one or more other compounds, a chemical reaction takes place. Example: the formation of rust when iron and oxygen combine. Sodium acetate, carbon dioxide, and water are produced when vinegar and baking soda are combined.

As long as the mass of the reactants before the reaction is equal to the mass of the products after the reaction, mass is conserved in chemical reactions even when new products are formed.

Thus, Option D is correct.

Answer is: 4. the forward and reverse reaction rates are the same.

The reaction rate is the speed at which reactants are converted into products.

The formation constant can be calculated when chemical equilibrium is reached, when the forward reaction rate is equal to the reverse reaction rate.

In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time.  

Reaction rates of the forward and backward reactions are equal and there are no changes in the concentrations of the reactants and products.
