The answer to this question is -27. This is taught in math class.
5h+11=13h-21 -5h +21 -5h +21 32=8h /8 /8 4=h
3 + 11 + 11 + 11 + 12 + 13 + 15 + 15 + 16 + 17 + 19 = 143
2H
28 11 points in 1 quarter because 44/4 = 11 and the fraction is 11 over 1!
H
H+ or a proton.
(b+h)(b+h)= b2+2hb+h2.
h = +11 and/or -11
I would tell, no reaction will occur the way the question has been asked.
40
H plus H is H2.Hydrogen gas is formed.
