Answer:
Temperature
Explanation:
Temperature measures the average kinetic energy of the particles in a substance. Thermal energy measures the total kinetic energy of the particles in a substance. The greater the motion of particles, the higher a substance's temperature and thermal energy.
<span>Compared to a weak acid, a strong acid has a greater habit of losing it's proton (hydrogen). For example, when hydrochloric acid (strong) encounters water, it is much more likely to donate its hydrogen to water, compared to nitrous acid (weak).</span>

Answer: 6.38 moles of are needed to react with 2.55 mol of
Explanation:
The balanced chemical reaction for the combustion of ethyne is:
According to stoichiometry:
2 moles of require = 5 moles of
Thus 2.55 mol of require = moles of
Thus 6.38 moles of are needed to react with 2.55 mol of
