HELP!! When nitroglycerin (C3H5N3O9) explodes, it decomposes into the following gases: carbon dioxide, nitrogen, nitrogen monoxide, and water vapor. If 239g of nitroglycerin explodes, what volume of water vapor will be produced at 45.00 inHg and 2678C?

Carbon monoxide, and water vapor was analyzed and found to contain 4.5 mol of carbon dioxide, 4.0 mol of carbon monoxide and 1.5 mole of water vapor. ... An ideal gas sample weighing 0.548 g at 100°C and 0.993 atm has a volume of 0.237 ... VSEPR predicts that an IF5 molecule

Explanation:

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
