What is the heat energy required to raise the temperature of 7 grams of dry air from 6°C to 12°C?

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

the ratio of the conjugate base to the acid required to attain the desired ph.

i'm wiling to try and you : )

i believe the answer is 5,000
