Calculate the number of moles of hydrogen gas that can be produced by the reaction of 0.750 moles of hydrochloric acid with calcium. |
|
Answer» Ca (s) + 2HCl → CaCl2 + H2\(\uparrow\) From the above balance chemical equation. we can conclude that. 2 moles of HCl react with one mole of Ca to produce one mole CaCl2 and one mole of hydrogen gas. \(\therefore\) 0.750 mole HCl on reaction with Ca can produce = \(\frac12\times0.750\) mole H2 gas = 0.375 mole H2 gas. |
