Hey there!
Na is sodium, which has 11 protons.
The more realistic amount of neutrons for this atom to have is 12. 23 would be the sum of protons and electrons.
The atom has a charge of 1+, so there is one less electron than protons, so
11 - 1 = 10 electrons.
Your answer is d. it has 11 protons, 10 electrons, and 12 neutrons.
Hope this helps!

Answer:
7.5 moles of CaBr2 are produced
Explanation:
Based on the equation:
2AlBr3 + 3CaO → Al2O3 + 3CaBr2
<em>2 moles of AlBr3 produce 3 moles of CaBr2 if CaO is in excess.</em>
<em />
Using this ratio: 2 moles AlBr3 / 3 moles CaBr2. 5 moles of AlBr3 produce:
5 moles AlBr3 * (3 moles CaBr2 / 2 moles AlBr3) =
<h3>7.5 moles of CaBr2 are produced</h3>
