B. 1, 1, 1, 2
Explanation:
You only need to balance the NaNO3 on the right. Since there is 2 NO3 on the left, you need to put a 2 in front of the NaNO3 on the right. Everything else is already balanced so the only coefficient needed is 2 in front of the NaNO3.
Answer:
the petrochemical industry
Explanation:
"Petrochemicals are the chemical products obtained from petroleum by refining. Some chemical compounds made from petroleum are also obtained from other fossil fuels, such as coal or natural gas, or renewable sources such as maize, palm fruit or sugar cane." - Textbook excerpt
To find out the molar mass, you have to break down each of the elements, then add them up.
C6 = 12.01 x 6 = 72.06 (Beacause, there are 6 carbon atoms)
H12 = 1.01 x 12 = 12.12 (Because, there are 12 hydrogen atoms)
O6 = 16.00 x 6 = 96 (Because there are 6 oxygen atoms)
Now, you will add all three of the elements up: 72.06 + 12.12 + 96 = 180.18.
So the molar mass of glucose is 180.18.
There are 66 neutrons in a single atom of indium-115. The atomic number of indium-115 is 49, meaning there are 49 protons. Then the atomic mass is 115, so 115-49 = 66.
