<u>Answer:</u>
The element is Chromium.
<u>Explanation:</u>
The atom has 24 protons and 12 neutrons.
We know that Cr has 24 number of protons, to the Chemical is Cr (Chromium)
Again, we know that the atomic number is the number of protons and the atomic mass is the sum of proton and neutron.
So, the atomic number is 24 and the atomic mass is (24+12)= 36
Therefore, the symbol is 
All sides of a square are equal, so set the two equations equal to each other and solve.
5x - 8 = 3x + 14
2x - 8 = 14
2x = 22
x = 11
Divide 346 mi by 22 gal.
The quotient will be "miles per gallon", which is exactly what you want.
