(b) at 400k both compounds are gases. at this temperature, which compound, ch4(g) or ccl4(g), behaves more like an ideal gas? justify your answer, including reasoning about both molecules.

Answers

CH4 has more ideal gas behavior than CCl4 due to its higher intermolecular interaction.

We must note that ideal gases have minimal interaction with each other. Hence, in deciding which gas has ideal gas behavior, we have to consider the gas that has the least degree of intermolecular interaction.

However, the both gases contain nonpolar molecules but CCl4 has a greater molecular mass and has more intermolecular interaction than CH4 hence CH4 has greater ideal gas behavior than CCl4.

What is thermal energy ?

The term thermal energy is defined as the energy contained within a system that is responsible for its temperature.It is formed when the atoms and molecules in a substance vibrate faster due to a increase in temperature.

The examples of thermal energy sources are fossil fuels like natural gas, coal and oil, and solar heat, heat pump electric heat, and geothermal heat.

Thus, during changes of state water particles maintain a constant speed, option B is correct.

Answers

Answer:

15 L

Explanation:

The important thing to remember about reactions that involve gases kept under the same conditions for pressure and temperature is that the mole ratios that exist between the gases are equivalent to volume ratios.

When a magnesium is heated, it burns in air with a dazzling white flame to form a white powder .What it called? ​

Answers

When a magnesium is heated, it burns in air with a dazzling white flame to form a white powder called Magnesium oxide.

Magnesium + oxygen → Magnesium oxide.

The burning of magnesium in air to form magnesium oxide is an example of a chemical reaction . In this chemical reaction there are two reactants ' magnesium and oxygen ' but only one product ' magnesium oxide '. The properties of the product magnesium oxide are entirely different from those of the reactants magnesium and oxygen.

the photo has the question; please help asap ! i’m giving brainliest—i also have more chemistry, honestly i’m about to post a whole bunch of questions

Answers

Answer:

The process is to divide the molecules by Avogadro's number (6.02 x 10^23) to get the moles. And since it's specified at STP (standard temperature and pressure) we know that the molar volume would be 22.4L. So we can just multiply the moles by the molar volume in order to get the volume of H2S.

(2.18 x 10^24) / (6.02 x 10^23) = 3.62 moles (rounded)

Now just multiply the moles by the molar volume of STP, 22.4.

3.62 x 22.4 = 81 Liters (rounded) of H2S

The molar mass of water (H2O) is 18. 0 g/mol. A sample of water has a mass of 18. 0 g. How many moles of water are contained in this sample? 1. 00 18. 0 36. 0 324.

Answers

1 mole of water is contained in a sample of water that has a mass of 18.0 g.

HOW TO CALCULATE NUMBER OF MOLES:

The number of moles of a substance can be calculated by dividing the mass of that substance by its molar mass.

no. of moles = mass ÷ molar mass

According to this question, a sample of water has a mass of 18.0g. The number of moles is calculated as follows:

no. of moles of H2O = 18.0g ÷ 18g/mol

no. of moles of H2O = 1mol

Therefore, 1 mole of water is contained in a sample of water that has a mass of 18.0 g.
