Question

We only can make ozone layer by adding 3 oxygen atoms or we cannot

Answer 1

If there is a question here I don't see it.

Answer 2

If 1.30g of steam at 100.0 ∘C condenses into 40.0g of water, initially at 31.0∘C, in an insulated container, what is the final temperature of the entire water sample? Assume no loss of heat into the surroundings.

Answer 3

Remember you get faster service if you don't post piggy back. Go to the top of the page and post your own question all by itself.
heat lost by steam + heat lost by 1.3g liquid H2O + heat gained by 31 degree H2O = 0

[mass steam x -heat vap] + [mass steam to H2O x specific heat H2O x (Tfinal-Tinitial)] + [mass cool H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Substitute and solve for T final. I get something like 49 C or so if I didn't goof. Post your work if you get stuck.
