Some commercial drain cleaners contain a mixture of sodium hydroxide and aluminum powder. When
the mixture is poured down a clogged drain, the following reaction occurs:
2NAOH(aq) + 2Al(s) + 6H,O(1) → 2NAAI(OH)4(ag) + 3H2(g)
The heat generated in this reaction helps melt away obstructions such as grease, and the hydrogen gas
released stirs up the solids clogging the drain. Calculate the volume of H, formed at 22.5°C and 1.00
atm if 4.00 g of Al is treated with an excess of NaOH.
Consider the following reaction.
(a) Is the reaction exothermic or endothermic?
exothermic
endothermic
CH3OH(g) → CO(g) + 2 H₂(g) AH +90.7 kJ
(b) Calculate the amount of heat transferred when 35.0 g of CH3OH(g) are decomposed by this reaction at constant pressure.
ΔΗ= 100.8
(c) If the enthalpy change is 19.0 kJ, how many grams of hydrogen gas are produced?
