What was Anton van Lee

there are 12 grams in 6.02x10^23 molecules of Na(NO3)3?

Explanations:- Looking at the given name, the parent chain name is Oct and Oct stands for eight carbons.

The suffix -ene at number 5 stands for a double bond between carbon number 5 and 6.

Bro stands for Br. Since the name has dibromo means there are two Br at number 3 and 7 carbons.

Similarly, there are two Cl at number 4 and 6 carbons.

Suffix -ol is used for OH group. The given name has 1,2-diol means there are two OH groups at number 1 and 2 carbons.

So, to draw the structure of the compound we put 8 carbons in a chain and then but a double bond between number 5 and 6 carbons. Put OH at number 1 and 2 carbons, put Br at number 3 and 7 carbons and Cl at number 4 and 6 carbons. If any of the carbons octet (four bonds) is still incomplete then we attach H atoms to it.

So, the structure of the compound is as given below:

Answer: 1ml of NaOH and 49 ml of Water

Concentration of NaOH to make: 0.001 M ( C1 )

Volume of NaOH to make: 50 ml ( V1 )

Concentration of NaOH in stock: 0.05 M ( C2 )

Volume of stock to use: V2

Using the formula C1 V1 = C2 V2 which is the standard formula for determining the dilutions to acquire a specified volume and concentration, we get:

0.001 M x 50 ml = 0.05 M x V2

V2 = 1 ml

So using 1ml of 0.05 M NaOH and 49 ml of Water

The answer is 4. (The word auditory always has something to do with hearing or the ear.)

Answer:

The density of air goes down as you get higher with altitude.

Explanation:

Less air is pushing down on the molecules below it as you go up. This means that it is not as compacted, another word for which is dense.

The density of the air decreases with the increasing elevation (altitude).

Altitude is the height or distance measured in the up or vertical direction.

The higher the elevation, the less dense the air will be.

There are two reasons for this:

There is less air pushing down from above at higher altitudes, and gravity is weaker further away from the Earth's center.

As a result, air molecules may spread out more at higher altitudes, and air density drops.

Thus, As you go higher, the density of the air drops.

Final answer:

Using the balanced chemical equation [tex]2 ZnS + 3 O2 - 2 ZnO + 2 SO2[/tex], it is calculated that 2.7 moles of O2 can produce 1.8 moles of zinc oxide.

Explanation:

To determine how many moles of zinc oxide can be produced from 2.7 moles of oxygen, we need the balanced chemical reaction involving zinc and oxygen forming zinc oxide. The relevant equation is: [tex]2 ZnS + 3 O2 - 2 ZnO + 2 SO2[/tex].

From the equation, we can see that 3 moles of oxygen react to produce 2 moles of zinc oxide. Therefore, if we start with 2.7 moles of oxygen, we can use a simple ratio to find the number of moles of zinc oxide produced:

3 moles of O2 produce 2 moles of ZnO.

2.7 moles of O2 will produce (2.7 moles O2 * 2 moles ZnO / 3 moles O2) = 1.8 moles of ZnO.

Thus, 1.8 moles of zinc oxide will be produced from 2.7 moles of oxygen.

The theoretical yield of ethyl chloride, given 27.17 g of ethylene and 58.33 g of hydrogen chloride, is 62.67 grams.

The first step in calculating the theoretical yield is to find the number of moles of each reactant. Given the masses and molecular weights, we find that there are 0.97 moles of ethylene and 1.6 moles of hydrogen chloride. The balanced equation shows that the reaction occurs in a 1:1 ratio, so the limiting reactant is ethylene as we have less of it.

The theoretical yield is therefore based on the amount of ethylene. Given the molar mass of ethyl chloride (64.5 amu), the theoretical yield would be the number of moles of ethylene multiplied by the molar mass of ethyl chloride. Therefore, the theoretical yield of ethyl chloride is 62.67 grams (rounded to the nearest hundredth without units).

The theoretical yield of ethyl chloride from the reaction of 27.17 g of ethylene with 58.33 g of hydrogen chloride is 62.61 g. Ethylene is the limiting reactant, and the yield is calculated using its moles and the molar mass of ethyl chloride.

To calculate the theoretical yield of ethyl chloride, we need to first determine the limiting reactant between ethylene and hydrogen chloride. We then use stoichiometry to find how much product can be formed from that limiting reactant.

First, calculate the moles of each reactant:

The stoichiometry of the reaction is 1:1, so:

Since we have more moles of HCl (1.5981 mol) than ethylene (0.9706 mol), ethylene is the limiting reactant. Now, we calculate the theoretical yield based on the moles of ethylene:

Theoretical yield of ethyl chloride (CH3CH2Cl) = 0.9706 mol * 64.5 g/mol = 62.6137 g

Therefore, the theoretical yield of ethyl chloride is 62.61 g when rounded to the nearest hundredth of a gram.

Final answer:

The number below each element's symbol on the periodic table refers to the atomic mass, which is different from the atomic number indicated by a subscript to the left of the symbol.

Explanation:

The number below each element's symbol on the periodic table represents the atomic mass of the element. This is different from the atomic number, which is represented as a subscript to the left of the element's symbol. Every element has a distinct symbol, typically the first one or two letters of its name, and the atomic number above each symbol in the periodic table indicates the number of protons in each element. For example, the element Carbon (C) has the atomic number 6, indicating it has 6 protons, and its atomic mass is shown beneath the symbol on the periodic table.

760 mmHg = 1 atm Therefore 30 atm = 760 * 3 mmHg = 2280 mmHg p1 = 700 mmHg p2 = 2280 mmHg You can compare them from there. You may also convert mmHg to atm by dividing by 760.

Question 2: Biofuel

Question 3: Geothermal

The correct answer is - C. Warm water is carried to cooler parts of the ocean.

The Gulf Stream is warm ocean current. It is an ocean current that originates from the Caribbean region, where it is constantly warm throughout the year. Because of that, the water is warm as well, and since the warm water is less dense, it moves on the surface. The movement is toward the higher latitudes, where this current, as a surface movement of the water, is bringing warmer water to the cooler areas, such as the eastern coast of the United States. Not only that warm water is brought to these areas, but the Gulf Stream also brings in warm and moist air masses with it, making the climate much more mild, and increasing the amount of precipitation.

= 553.28 mmHg

According Boyle's the volume of a fixed mass of a gas is inversely proportional to pressure at constant temperature.

P1V1 =P2V2

P1 = 988 mmHg

V2 = 0.56 L

V2 = 1.0 L

P2 = ?

P2 = P1V1/V2

     = (988 × 0.56)/1

      = 553.28 mmHg

Boyle's Law explains the relationship between gas pressure and volume at constant temperature and amount of gas. By applying Boyle's Law formula, we can calculate the gas pressure in the new 1.0 L flask. The pressure in the new flask is approximately 554.86 mm Hg.

Boyle's Law: Boyle's Law states that the pressure of a gas is inversely proportional to its volume when the temperature and amount of gas remain constant.

Using Boyle's Law formula, we can calculate the new pressure in the 1.0 L flask: P1V1 = P2V2. Plugging in the values, (988 mm Hg)(0.56 L) = P2(1.0 L), we find P2 = 554.86 mm Hg.

The gas pressure in the new 1.0 L flask will be approximately 554.86 mm Hg.

Over millions of years the layers of sediment become squashed and form sedimentary rocks. The shells of dead marine organisms fall to the sea bed and become part of the sediment. Marine organisms used the dissolved carbon dioxide to make calcium carbonate for shells. Carbon dioxide dissolved in the oceans.

Final answer:

Carbon is locked up in sedimentary rocks through the burial and transformation of organic material from living organisms into fossil fuels and organic-rich rocks like shale and carbonate rocks such as limestone.

Explanation:

Carbon becomes locked up in sedimentary rocks through a series of processes that are part of both the biological and geological carbon cycles. In the biological cycle, living organisms, mainly plants, consume carbon dioxide from the atmosphere to build their tissues. Upon death, this organic material may be buried under sediment and over millions of years, transform into fossil fuels like coal, or become part of organic-rich shale and limestone.

Carbonate rocks like limestone primarily form through the accumulation of marine organisms' calcite shells. The weathering of rocks on land also releases carbon to the soil, which can eventually become part of sedimentary layers. Over time, the carbon from these processes becomes compacted and cemented into sedimentary rocks, thereby locking the carbon away for prolonged periods, typically ranging from tens of millions to billions of years.

I think it is H. Boiling Point

Answer:

Boiling point

Explanation:

If you want to find the boiling point of an unknown liquid, just use beaker, a hot plate, and a temperature probe.

Boiling is characterized by the rapid transition from liquid to gaseous, with the formation of vapors (bubbles) inside the liquid. As in fusion, there is a temperature (boiling point) at which a given substance changes from a liquid to a gaseous state. This temperature is the boiling point.

In the case shown in the question above, you will need to pour the liquid into the beaker and heat it up with the hot plate. With the temperature probe, you will mark the temperature that the liquid started to boil.

Answer:

1 x 10^-10 M

Explanation:

We know that;

[H+][OH-] = 1 × 10^-14

Therefore;

when [H+] is 1 x 10^-7 then [OH-] will be;

= [1 × 10^-14]/[1 x 10^-7]

= 1 x 10^-7

When the [H+] changes from 1 x 10^-7 to  [1 x 10-4]

then the [OH-] will change from 1 x 10^-7 to;

 = [1 × 10^-14]/[1 x 10^-4]

 = 1 x 10^-10 M

Thus; the new [OH] is 1 x 10^-10 M

The molar amount of gas can most likely be found by using the ideal gas law. This is because the ideal gas law states pV = nRT. P, V, and T are the pressure, volume, and temperature, which are the known variables. The R stands for the Universal Constant of Gases; also known. Therefore, the unknown is n, the number of moles (molar amount) of gas, and so you would solve for n from the law.

Answer: A) The molar amount of gas
