If the equation is balanced: The coefficient numbers in the equation show the number of molecules, formula units, or atoms of the species involved in.
A cloud is made up of liquid water droplets. A cloud forms when air is heated by the sun. As it rises, it slowly cools it reaches the saturation point and water condenses, forming a cloud. As long as the cloud and the air that its made of is warmer than the outside air around it, it floats!
Cloud: a visible aggregate of tiny water droplets or ice crystals or a mixture of both suspended in the air. It forms when the condensation (or deposition) of water vapor meets supersaturation conditions (that is, relative humidity greater than 100%) within the air that is free of dust and other aerosols.
