What forms when chemical reactions combine pollution with sunlight

What are atoms of the same element with varying number of neutrons

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.

The force it would take to accelerate an 900-kg car at the rate of 6m/s2
