Which is the correctly balanced equation? question 3 options: cl2 + nai à nacl + i2 cl2 + 2nai à nacl + 2i2 2cl2 + nai à 2nacl + i2 cl2 + 2nai à 2nacl + i2

I'm pretty sure that Cl2 + 2NaI à 2NaCl + I2  is a correctly balanced equation.

Evaporation: this is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas). water vapour droplets join together to make clouds! condensation: this is when water vapour in the air cools down and turns back into liquid water.
