Yo can someone help me out

Answer: A

Explanation: liquids and basses are less dense than a solid

Answer:

First off welcome to brainly

the answer is C

Explanation:

If you put water in a glass it takes the shape, right? It doesnt just sit on top refusing to go in. Its the same with gas. If you can manage to capture gas it will form to the glass instead of staying in the same state.

Hope I helped, have a good one :)

Calculate the ΔHrxn for the following


Fe2O3(s)+3CO→Fe(s)+3CO2(g)
Given:
4Fe(s)+3O2(g)→2Fe2O3(s)
