I think it’s A because each unit is worth 3
they would be more detailed? what type of cells though?
Answer:
2 Na + 1 Cl2 -> 2 NaCl
Explanation:
The answer is really simple, because if you have 1 nonmetal element that has a subscript of 2, you need to multiply the product and the first reactant by 2 to balance it.
<span>Inside the nucleus of an atom are protons and electrons. </span>
The balanced chemical reaction is:<span>
</span><span>2C6H6 + 15O2 → 12CO2 + 6H2O</span><span>
We
are given the amount of carbon dioxide to be produced for the reaction. This will
be the starting point of our calculations.
</span>42 g CO2 ( 1 mol CO2 / 44.01 g CO2) ( 2 mol C6H6 / 12 mol CO2 ) (78.1074 g C6H6 / 1 mol C6H6) = 12.42 grams of C6H6
