<h2> The amount of Hcn formed in grams is = 0.06223 grams</h2><h3> calculation</h3>
write the equation for reaction
that is; KCn + HCl → KCl + HCn
step 1:find the moles of KCn reacted
moles of KCn = mass of KCn/molar mass of KCn( 65.12 g/mol)
= 0.150 g/ 65.12 g/mol =2.303 x10^-3 moles
step 2: use the mole ratio between KCn :HCn which is 1:1 to determine the moles of HCn which is also 2.303 x 10^-3 moles
step 3: find the mass of HCn =moles of HCn x molar mass of HCn
= 2.303 x10^-3 x 27. 02 =0.06223 grams
The answer is A. Ethanol. Ethanol is an active principal in alcoholic beverages

The answer to your question would more than likely be chemical energy, natural gas, and chemical energy. but I don't know what grade your in I'm in eighth if your below I know the answer. I'm pretty sure I had a question exactly like this last year but that was last year so if it's wrong sorry. I looked it up on Google to make sure
