Answer:

the reactants are na and cl2 the products is the combination nacl --the law of conservation of matter keeps reactions balanced. No you would not be adding more atoms that is what the first combo is. The coefficient 2 stands for 2 atoms of KL

Answer:

Explanation:

There are 2 oxygens on the reactants side (OH)2 but 4 on the products side (2H2O). You cannot get 2 oxygens out of nowhere, so it is not balanced.

SIZIF [17.4K]

Answer:

See image attached and explanation

Explanation:

The stratospheric ozone layer is very important in absorbing high-energy ultraviolet radiation that is harmful to living systems on earth. The concentration of ozone in the stratosphere is determined by both thermal and photochemical pathways for its decomposition. Nitric oxide, NO, is a trace constituent in the stratosphere that reacts with ozone to form nitrogen dioxide, NO2, and the diatomic oxygen molecule. The nitrogen-oxygen bond in NO2 is relatively weak. When an NO2 molecule encounters an oxygen atom, it transfers an oxygen, forming O2 and NO. The chemical reactions involved are formations of NO2 following by reaction of NO2 with atomic oxygen for form NO and O2. The sum of both reactions show that the overall reaction is simply the reaction of ozone with atomic oxygen to form two molecules of molecular oxygen. Hence, NO only serves as a catalyst, it does not undergo a permanent change itself.
