10 mar 2020 · N 2 + 3H 2 → 2NH 3. Step 2: Turn the 25 g of hydrogen gas (H2) into moles by using the molar mass. The molar mass of hydrogen is 1.008 g/mole. so for H2 it is 1.008(2) = 2.016 gram/mole: 12.4008 moles. Step 3: Use the molar ratios to find the moles on ammonia produced
Given the chemical equation: N2 + 3 H2 → 2 NH3. On a molecular level, what do the coefficients mean? 1 molecule of nitrogen reacts with 3 molecules of hydrogen to give 2 molecules of ammonia.
12 gru 2016 · My try:: Because we have 10 L of nitrogen gas, we have 10/22.4 moles = 0.446 moles of nitrogen gas, and thus need 0.446 * 3 = 1.338 moles of hydrogen gas. As such, we need 2.676 grams of hydrogen gas, or 2.676/0.09 = 29.8 L of hydrogen gas.
Diatomic N2 can react with diatomic H2 to form ammonia (NH3). The balanced chemical equation is: N2(g) + 3 H2(g) → 2NH3(g) If 6 moles of H2 totally reacted with more than enough N2, how many moles of ammonia would be expected to form? A) 6 moles B) 3 moles C) 4 moles D) 2 moles E) not enough information
Balanced equation: N2 + 3H2 -> 2NH3? mol NH3= 6 mol H2 x 2 mol NH3----- ----- = 4 mol NH3 3 mol H2 When Magnesium burns in air, it combines with oxygen to form magnesium oxide according to the below equation: What mass (g) of magnesium oxide is produced from 2.00 mol of magnesium?
Here’s the best way to solve it. Identify the balanced chemical equations involved in the reaction and determine the molar masses for N 2 and N H 3. (1) The balanced reaction is N2 + 3H2 ---> 2 NH3 Molar mass (g/mole) 28 17 From the balanced reaction, 1 mole = 28 g of N2 produces 2 mole*17g/mole = 34g of NH3 12.0 g of N2 produces (…
Stoichiometry, by definition, is the calculation of the quantities of reactants or products in a chemical reaction using the relationships found in the balanced chemical equation.
