Look at the equation for making chlorine gas and decide which answer will provide you with the numbers to balance it
aKMnO4 + bHCl aKCl + aMnCl 2 + xH2O + yCl.
Answer:
6) E
Most efficient way: make equations.
Equation for Cl
b = a + 2a + 2y
b = 3a + 2y
Let us check which of the options can satisfy the equation above.
A – Wrong
8 ≠ 3 + 6
B – Wrong
8 ≠ 3 + 8
C – Wrong
4 ≠ 3 + 2
D – Wrong
16 ≠ 6 + 12
E – Correct
