Pretty sure it shows a chemical reaction
Answer:
80 liters
Explanation:
At STP, 1 mole of ideal gas has a volume of 22.4 liters.
Therefore, since liters and moles are directly proportional, we can use stoichiometry directly.
40L CH₄ × (2L H₂ / 1L CH₄) = 80L H₂
SiO2 is the chemical formula silicon and oxygen
We have to solve this question using the stoichiometry of the reaction:
The equation of the reaction is;
![2 C12H26(l) + 37 O2(g) -----> 24 CO2(g) + 26 H2O(l) + 15,026 kJ](https://tex.z-dn.net/?f=2%20C12H26%28l%29%20%2B%2037%20O2%28g%29%20-----%3E%2024%20CO2%28g%29%20%2B%2026%20H2O%28l%29%20%2B%2015%2C026%20kJ)
According to the question;
Number of moles of CO2 released = 21.3 g/44 g/mol = 0.48 moles
From the stoichiometry of the reaction:
Since;
24 moles of CO2 released 15,026 KJ
0.48 moles of CO2 will release 0.48 * 15,026/24
= 301 KJ of heat.

The amount of heat deposited on the skin is 2.26 kJ.
<h3>What is the amount of heat given off by 1.0 g of steam?</h3>
The amount of heat given off by steam is determined using the formula below:
Quantity of heat = mass * latent heat of vaporization.
Moles of steam = 1.0/18
Heat = 1.0/18 * 40.7
Heat deposited = 2.26 kJ
In conclusion, the quantity of heat is determined from the latent heat of vaporization and the moles of steam.
