PLS HELP ME WITH THIS ALGEBRA! The reaction of 65.4g of zinc and 72.9g of hydrochloric acid produces 136.3g of zinc chloride and 2gof hydrogen, find the weight of hydrochloric acid necessary for a complete reaction with 300g of zinc and the weight of hydrogen produced.

Step-by-step explanation:

Perimeter = L1 + W1 + L2 + W2          L1 = L2 = L  = 70 ft       W1 = W2 = W = 30 ft

                 = L + W + L + W        

                 = 2L + 2W          

                 = 2(70) + 2(30)

                 = 140  +  60

                 = 200

Perimeter the movie screen  is 200 ft
