In the decomposition of water. how many grams of hydrogen will be produced by 20g of water?

The equation for the reaction is is  2H2O = 2H2 + O2

Ratio of H to O in water = 2:1

Molar mass of water = 2*1.008 + 15.999 =  18.015

18.015 g gives 2*1.008 hydrogen

20  gives  2* 1.008 * 20 / 18.015

= 2.24 g hydrogen to the nearest hundredth.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

the dependant variable is spilled water

the independent is the heat
