Question

zinc carbonate is heated strongly to give zinc oxide and carbon dioxide ​

Answer 1

Explanation:

s = d ÷ t. speed = distance ÷ time.

a = (v-u) ÷ t. acceleration = change in velocity ÷ time.

F = m x a. Force = mass x acceleration.

w = m x g. weight = mass x gravity.

p = m x v. momentum = mass x velocity.

(mv - mu) = F x t. change in momentum = Force x time.

d = m v. density = mass ÷ volume.
