Answer:
2 grams.
Explanation:
H2 + O2 ---> H2O2
Using molar masses:
2*1 g hydrogen reacts with 2*16 g oxygen.
so 2g H2 reacts with 32 g O2.
Answer:
The answer to your question is 2 moles of Carbon
Explanation:
Carbon-12 means it has a molecular mass of 12g / mol. Mol is defined as the number of grams of an atom in one mol.
To solve this problem, we use proportions
12 g of Carbon ---------------- 1 mol of Carbon
24 g of Carbon -------------- x
x = ( 24 g x 1 mol ) / 12 g
x = 24 / 12
x = 2 mol of Carbon

Answer: 160.40 g Fe2O3 are needed.
Explanation:
Balanced equation: 2 Al + Fe2O3 —> Al2O3 + 2Fe
54.2 g Al * 1 mol Al / 26.98 g Al * 1 mol Fe2O3 / 2 mol Al * 159.69 g Fe2O3 / 1 mol = 160.40 g Fe2O3 are needed.
Answer:
Explanation:
Hello!
In this case, since the Dalton's law help us to realize that the total pressure of a gas mixture is computed by adding the partial pressure of each composing gas, for the mixture formed by carbon dioxide, oxygen sulfide (should be hydrogen sulfide instead) and air, we can write:
Thus, given the total pressure and the partial pressures of both carbon dioxide and hydrogen sulfide, the partial pressure of the remaining air would be:
Therefore, we plug in to obtain:
Best regards!
If 6 units of AB were reacted with 10 units of CD in the described equation, the limiting reactant would AB
<h3>Limiting reactants</h3>
They are reactants that determine how far a reaction can go in terms of yield.
From the equation: 3AB + 4CD --> 2AD + 6CB
The mole ratio of AB to CD is 3:4
Thus, 6 units of AB will require 8 units of CD.
But 10 units of CD were reacted with only 6 units of AB. This means that CD is in excess by 2 units while AB will limit the yield of the reaction.
