Steel shot weighs about two-thirds as much.hoped i can i get brainliest

Your is  answer:   4.44*my answers too short so i'm just gonna write this so that it lets me submit it, lol*

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 : )
