Acetylene gas (c2h2) reacts with oxygen gas (o)
to produce carbon dioxide (co) and water vapor
(h20). how many liters of c2h2 are required to
produce 75.0 l of co2?
what volume of h20 is produced?
what volume of oz is required?
when making the calculations, did you need to
find the number of moles?

step-by-step explanation:

whole numbers, zero or greater

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
