When 3 moles Cu react 3 moles of copper nitrate are obtained.
How many moles of CO2 form when 15.5 ml of 3.00m HCl solution react?
Also 5,8 mol
4. The chemical equation is Cu + H2SO4 → CuSO4 + H2. Copper and sulfuric acid have the same coefficient (1), so the same number of moles of copper and sulfuric acid are used.
3,44 moles H2 react with 1,146 moles NH3. The limiting reactant is hydrogen. O,244 moles N2 remain. 19,5 g NH3 are obtained.
6 moles of HF react with 1 mole of SiO2.
The formula of methane is CH4. So 4 times that = 4 carbon moles and 8 moles hydrogen.
3Cu + 8HNO3 ----> 3Cu(NO3)2 + 2NO + 4H2O is the equation if it is dilute nitric acid. In concentrated nitric acid the equation is different. So 3 moles of copper produce 2 moles of NO. Therefore it requires 6 moles of copper to produce 4 moles of NO.
2 atoms (molecules) of hydrogen are needed to react with oxygen to form water.
10 moles of nitrogen dioxide are needed to react with 5,0 moles of water.
The equivalent number of moles is 0,57.
Molar mass of it is 63.5. So there are 0.02852 copper moles.
According to this balanced equation:Na2O + H2O --> 2NaOH42 moles Na2O react with 42 moles H2O
The answer is 3 moles oxygen.
This depends on the mass of copper oxide.
When 6,0 moles of H2 gas react with nitrogen, 4 moles of ammonia are produced.
