Answer:

Water breaking down into hydrogen and oxygen is a decomposition reaction

Hydrogen and oxygen combining to form water is a synthesis reaction

Explanation:

A decomposition reaction is a chemical reaction that involves the breakdown of a chemical reactant entity into two or more simpler product fragments

Water H₂O undergoes a decomposition reaction by breaking down into hydrogen, H₂,, and oxygen, O₂, as follows;

2H₂O (l) → 2H₂ (g) + O₂ (g)

A synthesis reaction is a reaction that involves the chemical combination of two or more dissimilar molecules or atoms to produce a different compound or molecule

Water, H₂O, is formed by a synthesis reaction of hydrogen, H₂,, and oxygen, O₂, combining as follows;

2H₂ + O₂ → 2H₂O

The difference in potential between the cathode and anode of a spark plug is 14700 v. what energy does the electron give up as i

Verdich [7]

The energy the electron gives up passing between the electrodes is equal to the product between its charge and the potential difference between the electrodes:
$\Delta U = e \Delta V$
where
e is the electron charge
$\Delta V$ is the potential difference

Plugging numbers into the equation, we find that the electron gives up is
$\Delta U = (1.6 \cdot 10^{-19} C)(14700 V)=2.35 \cdot 10^{-15} J$
