Answer: The correct answer is option B.

Explanation:

Average kinetic energy of the gas molecule is given by relation:

E_K=\frac{3}{2}\frac{R}{N_A}\times T

N_A = Avogadro Number

T = Temperature of the gas in Kelvins.

R = Universal gas constant

E_K\propto T

With increase in temperature the kinetic energy of the gas molecule increases and vice-versa.

So, according to the question the explanation for a drop in temperature of the gas is decrease in average kinetic energy of the gas molecules.

Hence, the correct answer is option B.

How many moles of methane will react to form 3.2 moles of carbon dioxide?
Hunter-Best [27]

Answer:

3.2 moles

Explanation:

First, we'll begin by writing a balanced equation for the Combustion of methane to produce carbon dioxide. This is illustrated below:

CH4 + 2O2 —> CO2 + 2H2O

From the balanced equation above,

1 mole of methane (CH4) reacted to produced 1 mole of carbon dioxide (CO2).

Therefore, 3.2 moles of methane (CH4) will react to produce 3.2 moles of carbon dioxide (CO2).

From the illustration above, 3.2 moles of methane is needed to produce 3.2 moles of carbon dioxide.

A. By referring to forces at work in the atomic nucleus, how can you
qwelly [4]

There is an unstable ratio of protons and neutrons. Because protons are positively charged but neutrons have no charge, an increase in the number of protons means there needs to be an increase in the number of neutrons to "bind" the nucleus together. This is because like charges repel, so the protons will repel each other, and if there aren't enough neutrons to act as "glue" to hold the nucleus together, the nucleus will break apart.
