Given the balanced equation for an organic reaction between butane and chlorine that takes place at 300°c and 101.3 kilopascals: c4h10+cl2->c4h9cl+hcl

Definitely 25.3 degrees celsius 

The chemical equation is ca(oh)2(s) + h2so4(aq) --> + h2o(l) in low concentrations it will stay in elucidation. at higher concentrations it will be precipitous.the oh- on the left responds with the h+ on the left to make hoh (h2o) as a produce. there's no oh- on the right hand side. so it should look like this:   ca2+ + 2oh- + 2h+ + so4^2- > caso4(s) + 2h2o(l)  hope this ! and mark me as brainliest if you dont mind : )

Action: n2(g) + 3 h2(g) → 2 nh3(g)
