Answer:
The standard heat of vaporization of nitrous oxide is 16.5 kJ/mol
Explanation:
The standard heat of vaporization , occurs as the result of a change in heat when 1 mole of a liquid is vaporized. The standard heat of vaporization is always positive i.e endothermic. In the given question, we are asked to determine what the standard heat of vaporization of nitrous oxide.
i.e
Answer:
Write a balanced equation for the extraction of zinc in a blast furnace pls help quick
The mass, in grams, of hydrogen that would be produced from the reaction will be 0.102 grams
<h3>Stoichiometric calculations</h3>From the balanced equation of the reaction:
The mole ration of magnesium to water is 1:2.
Mole of 4.73 grams Mg = 4.73/24.3 = 0.195 moles
Mole of 1.83 grams water = 1.83/18 = 0.102 moles
Hence, water is limiting.
Mole ratio of water to the hydrogen produced = 2:1
Equivalent mole of hydrogen gas produced = 0.102/2 = 0.05 moles
Mass of 0.05 moles hydrogen gas = 0.05 x 2 = 0.102 grams
