A magnesium ribbon is burnt in the air to form the grayish oxide of magnesium - magnesium oxide (Mgo). How would you classify it?

1. they vary with a higher number because boiling is way hotter than melting

it would be a gas formation

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
