Decomposition is the example of a reaction in which hydrogen and oxygen are produced by running an electric current through water.
Decomposition of water through electrolysis of water into oxygen and hydrogen gas due an electric current passed through water. when an electric current is passed through water, oxygen gas is being produced at the anode and hydrogen gas is produced at the cathode.
Answer: Thus 0.724 mol of
are needed to obtain 18.6 g of 
Explanation:
To calculate the moles :

According to stoichiometry :
2 moles of
are produced by = 1 mole of 
Thus 1.09 moles of
will be produced by =
of 
But as yield of reaction is 75.6 %, the amount of
needed is =
Thus 0.724 mol of
are needed to obtain 18.6 g of 
Answer:
None of them, D
Explanation:
The actual answer is chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions.
7.30 x 10^-7 km. the others have 4 significant figures.
Answer:
The total number of orbitals for a given n value is n2.
Explanation:
For a hydrogen atom with n=1, the electron is in its ground state; if the electron is in the n=2 orbital, it is in an excited state.
