2h + 2h + 2h = 6h
3h + 20 - h + 5 = 2h + 25
6h+4g
76-2*6=444
v=pi.r^2h
True
- 3h - 2h + 6h + 9 = h + 9
It is: 11h
Carbonic acid, H2CO3
H is 30
3h-5h + 11 = 17 is ------2h + 11 = 17- 11 -11____________-2h = 6___ ___-2 -2h = -3 (This is the answer.)
2H+ + SO42- + Ca2+ + 2I- CaSO4 + 2H+ + 2I-
(x + 2)(h + t)
(t+h)(x+2)
The formula for H plus 1 plus H minus 1 is 2H. This is because the +1 and -1 charges cancel each other out, leaving only the H atom.
It is [(2a+2h+5) - (2a+5)]/h = 2h/h = 2
6h 8min
3+2h
