How many grams of H2 are needed to produce 10.06 g of NH3?
The formula reaction for NH3 when using N2 and H2 is: (N2)+3(H2) ---> 2(NH3) Now, first step is to find the moles of the H2 reactant. This is found via (grams of reactant)/(molar mass of reactant). There are 10 grams, and the molar mass of H2 is approximately 2.016. Therefore, the equation should look like: 10/2.016. This yields a value of ~4.9606 moles of H2. Now, you use the molar ratio from the reactant to the product to determine how many moles of product were yielded. According to the reaction, three moles of H2 are required to produces 2 moles of NH3. So, the mole ratio is 2/3. Multiply the number of moles of H2 with the molar ratio to determine the moles of NH3. 4.0606 * 2/3 = 3.3071 moles of NH3. Multiply the number of moles with the molar mass of NH3 (17.0306), and voila! 3.3071 * 17.0306 = 56.3216 grams. Now, if your teacher is feeling like a stickler about significant figures, than that value should be rounded to 56 grams of NH3.
If you have 3.64 g of H2 how many grams of NH3 can be produced?
To determine how many grams of NH3 can be produced from 3.64 g of H2, we first need to use the balanced chemical equation for the synthesis of ammonia: N2 + 3H2 → 2NH3. The molar mass of H2 is approximately 2.02 g/mol, so 3.64 g of H2 is about 1.80 moles. According to the reaction, 3 moles of H2 produce 2 moles of NH3, so 1.80 moles of H2 would produce approximately 1.20 moles of NH3. The molar mass of NH3 is about 17.03 g/mol, resulting in about 20.4 grams of NH3 produced.

How many grams of H2 can be produced from the reaction of 72 g sodium with water?
To determine how many grams of H2 can be produced from the reaction of sodium with water, we first use the balanced chemical equation: 2 Na + 2 H2O → 2 NaOH + H2. The molar mass of sodium (Na) is approximately 23 g/mol, so 72 g of sodium corresponds to about 3.13 moles of Na (72 g / 23 g/mol). According to the equation, 2 moles of Na produce 1 mole of H2, so 3.13 moles of Na will produce about 1.57 moles of H2. Since the molar mass of H2 is about 2 g/mol, this results in approximately 3.14 grams of H2 (1.57 moles × 2 g/mol).

How many grams of hydrogen are needed to produce 30.0 grams of water?
The synthesis reaction is 2 H2 + O2 = 2 H2O. Every two moles of hydrogen reacts with one mole of oxygen to make two moles of water. Then 30.0 grams of water is 1.67 moles, and 1.67 moles of H2 has a mass of 3.37 grams. 25.0 grams of O2 is .781 moles, so 1.562 moles of H2 are needed, or 3.15 grams.

How many moles of hydrogen gas will be produced if 25g of Na reacts completely with excess HCl?
Using the equation 2Na + 2HCl -> 2NaCl + H2, we can see that 2 moles of Na react with 2 moles of HCl to produce 1 mole of H2. Calculate moles of Na: 25g Na * 1 mol Na / 23g Na = 1.09 mol Na. Since the reaction is with excess HCl, the number of moles of H2 produced will be half the number of moles of Na, so it will be 0.545 moles of H2.
