Kelly ran electricity though a sample of water using electrolysis. the water changed into two gases, x and y. it was not possible to break down the gases x and y into simpler particles. which statement is best supported by this evidence?

Ibelieve the answer is weathering,hope my answer has you : ) 

The answer to the question: choose the correct statement.  a) when ethane reacts with fluorine gas the product is less stable.b) addition reactions of unsaturated hydrocarbons and halogens requires a high activation energy.  c)the double covalent bond within unsaturated hydrocarbons requires a lot of energy to break.  d)the double covalent bond within unsaturated hydrocarbons can be broken easily.is: a) when ethane reacts with fluorine gas the product is less stable.

Molar mass ca = 40.078 g/mol  molar mass cacl2 = 110.984 g/mol  % ca = 40.078 x 100 / 110.984 = 36.1

Tidal energy has a high energy density, meaning that the tides store a larger amount of energy than most other forms of renewable energy, such as the wind.
