PLEASE HELP If 12.8g of chlorine gas is reacted with 8.3g sodium iodide, how much sodium chloride will be produced?​

Use examples from the article to explain one positive and one negative effect that chemistry has had on society.

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)

What three things does a balanced equation show you?
