Answer:
A. 11
Explanation:
atoms are made of three types of sub atomic particles - protons, neutrons and electrons
Protons are positively charged, electrons are negatively charged and neutrons are neutral.
Protons and neutrons are located inside the nucleus and electrons orbit around the nucleus in energy shells.
Atoms make up an element and atoms are neutral charged with an equal number of protons and electrons. Neutral atom of sodium would therefore have an equal number of positive charges and negative charges.
Since Na has 11 protons, for it to be neutral it would have 11 electrons

A by-product of both fission and fusion is Energy.
Fission and fusion are nuclear reactions in which a large amount of energy is produced. Fission is actually the splitting of nuclei that is heavy and unstable into lighter nuclei in which large amount of energy is released and fusion is combination of two lighter nuclei that releases large amount of energy.
So fission and fusion both released large amount of energy.
Answer:
![K=3.9*10^{-82}](https://tex.z-dn.net/?f=K%3D3.9%2A10%5E%7B-82%7D)
Explanation:
Reactions:
With: ![K_1=\frac{[NO][O]}{[NO_2]}=6.8*10^{-49}](https://tex.z-dn.net/?f=K_1%3D%5Cfrac%7B%5BNO%5D%5BO%5D%7D%7B%5BNO_2%5D%7D%3D6.8%2A10%5E%7B-49%7D)
![O_3 (g) + NO (g) \longleftrightarrow NO_2 (g) + O_2 (g)](https://tex.z-dn.net/?f=O_3%20%28g%29%20%2B%20NO%20%28g%29%20%5Clongleftrightarrow%20NO_2%20%28g%29%20%2B%20O_2%20%28g%29)
With: ![K_2=\frac{[NO_2}{[O_3][NO]}=5.8*10^{-34}](https://tex.z-dn.net/?f=K_2%3D%5Cfrac%7B%5BNO_2%7D%7B%5BO_3%5D%5BNO%5D%7D%3D5.8%2A10%5E%7B-34%7D)
To achive the reaction we combine those two reactions:
The equilibrium constant:
![K= K_1*K_2=(6.8*10^{-49})*(5.8*10^{-34})=3.9*10^{-82}](https://tex.z-dn.net/?f=K%3D%20K_1%2AK_2%3D%286.8%2A10%5E%7B-49%7D%29%2A%285.8%2A10%5E%7B-34%7D%29%3D3.9%2A10%5E%7B-82%7D)
The chemical formula for table sugar is C12H22O11. From the formula, you can say that it is an organic molecule where in every molecule contains 12 atoms of carbon, 22 atoms of hydrogen and 11 atoms of oxygen. There are 45 atoms in total in one molecule of sugar.
