4. The reaction between kerosene and fuming HNO 3 is used as a rocket fuel. The balanced
reaction is listed below. How many liters of CO 2at STP would be formed from 86 moles
of nitric acid (HNO 3)?
C14H30(1) + 86 HNO3(1) ► 14 CO2(g) +86 NO2(g)

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

ok whats the question if not i cannot you i need question and need a thing to answer
