Answer: The given statement is false.

Explanation:

In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they move rapidly from one place to another leading to more number of collisions.

Hence, gases are able to expand more rapidly as compared to liquids.

Therefore, gases will expand to fill their container.

Whereas in liquids, the molecules are held by more strong intermolecular forces of attraction as compared to gases. Due to which they are not able to move much more freely.

Hence, liquids do not expand to fill their container.

Thus, we can conclude that the statement gases and liquids will both expand to fill their container, is false.

I think the correct answer would be false. <span>Gases do expand because they do not have an absolute volume. However, liquids do not expand to fill their container, they just fill and follows the shape of the container. Hope this answers the question.</span>

Which of these energy resources are renewable? Select all that apply.

xz_007 [3.2K]

The correct options are option B and D, that is, wind power and geothermal energy.

The form of energy which is gathered from renewable resources is known as renewable energy. This form of energy gets restocked on a human timescale like wind, sunlight, tides, waves, rain, and geothermal heat.

Renewable energy usually provides energy in four essential fields, that is, air and water heating/cooling, electricity generation, rural energy services, and transportation.

Based on this reaction, how many moles of H2 can be obtained starting with 3 mol CH4?

sleet_krkn [62]

Answer:

9 moles of H₂ are produced

Explanation:

Note: The question is incomplete. the complete question and the given image is found below:

The diagram represents a high-temperature reaction between CH4 and H2O. Based on this reaction, how many moles of H2 can be obtained starting with 3 mol CH4?

From the attachment, the equation of the reaction can be written as:

2CH₄ + 2H₂O ----> 2CO + 6H₂

From the equation the reaction shown above, 2 moles of methane, CH₄ reacts with 2 moles of gaseous water or steam, H₂O (since the reaction occurs at a high temperature) to produce six moles of hydrogen gas, H₂.

Therefore, starting with 3 moles of CH₄ and assuming the number of H₂O are equal to or greater than three moles (since the mole ratio of CH₄ to H₂O is 1 : 1 according to the equation of the reaction), number of moles of H₂ that will be produced = 3 * 6/2 moles of H₂

number of moles of H₂ produced = 9 moles

Therefore, 9 moles of H₂ are produced
