Birds cause a lot of damage to airplanes every year. To study this problem, the U. S. Air Force invented a chicken cannon. Air Force scientists use the cannon to shoot chicken bodies at airplanes in controlled tests. Then they analyze the damage the chicken bodies caused. Evaluate this model. In what way do you think it is helpful? What are some of its limitations?

Outermost (valence) electrons

The answer is the third choice

Apipe hope this . brainliest?

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 : )
