Isotope - the same element, but different atomic mass so 1)35 Cl and 37 Cl
Answer: it would be cation, 2+
Explanation: electrons are negatively charged by 1. So if you get rid of 2 electrons it would be positive and cation is used to represent positive ions.
1 proton, 1 electron, and 2 neutrons
80 liters of water
this is a mixture problem.
75% x 20 = 1500 (acid solution)
0 x X = 0 (water)
15 x 20+x = 300 + 15x
looking at column 3, we get 1500+0 = 300+15x
using properties, x=80
