Answer:
moles
Explanation:
The value of 3 in the chemical compound refers to the number of moles present of it.
Answer: According to the reaction: 2 mol of C2H6 produce 4 mol of CO2 5.70 mol of C2H6 ‒ x moles of CO2 So, number of moles of CO2 produced by combustion of 5.70 mol of ethane equals: Answer: n(CO2) = 11.4 mol.

Answer: option <span>C: H2O(l) at 10°C changes to H2O(l) at 20°C
</span>
Explanation:
To solve this questions use the fact the temperature is a measure of the average kinetic energy of the particles of a substance.
For a given substance, the higher the temperature the higher kinetic energy, the lower the temperature the lower the kinetic energy
That is a statement derived from the kinetic theory.
The kinetic energy states that as the temperature of a substance increases, so do the average velocity of its particles and so the average kinetic energy.
Thas is why gases have a higher kinetic energy than liquids and liquids have a higher kinetic energy than solids.
The options A<span>: H2O(s) changes to H2O(l) at 0°C and B: H2O(l) changes to H2O(s) at 0°C describe changes at constant temperature, so in them the average kinetic energy does not change.</span><span>
</span><span>
</span><span>The option C: H2O(l) at 10°C changes to H2O(l) at 20°C, as said, is the right answer because it is a process in which the temperature is increasing, so the average kinetiic energy is also increasing.</span><span>
</span><span>
</span><span>The option D: H2O(l) at 20°C changes to H2O(l) at 10°C corresponds to a decrease of the kinetic energy, since the temperature is decreasing.
