The bond that exist between two oxygen atoms is
called a double covalent bond. This bond involves the sharing of four electrons
to obtain a more stable structure. This type of bond is much stronger than the
single covalent bond. They are much harder to break.
603.040 has 5 significant figures in it I'm pretty sure
Answer:
B
Explanation:
A chemical reaction equation is balanced if the number of atoms of each element on the right hand side of the reaction equation is the same as the number of atoms of the same element on the left hand side of the reaction equation.
By inspection, the chemical reaction written in the question is a balanced chemical reaction equation.
However, the statement in option B that more molecules of N2 are needed to produce NH3 than molecules of H2 is a false statement since only one mole of N2 and three moles of H2 are required to produce NH3 according to the reaction equation as written in the question.
