PLEASE HELP When Li2CO3 & H2SO4 ard combined, what happens?

A. nothing
B. A gas & Liquid are produced
C. A precipitate is formed

B) A gas and liquid is produced.

Explanation:

In the reaction, H2SO4 + Li2CO3 -> Li2SO4 + CO2 + H2O, bubbles of carbon dioxide gas (CO2) are produced. ... This is an example of a carbonate-acid reaction, which in itself is a double-replacement reaction followed by a decomposition reaction.

Hope it helps.

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

d
