When potassium cyanide (KCN) reacts with acids, a deadly poisonous gas, hydrogen cyanide (HCN), is given off. Here is the equation:
KCN(aq) + HCI(aq) -> KCI(aq) + HCN (g)
In a sample of 0.140 grams of KCN is treated with an excess of HCI calculate the amount of HCN formed in grams.
Please explain the work and the answers.
