SiCl4(l) + 2 H2O(l) → 4 HCl(aq) + SiO2(s) So I thought that SiCL_4 was the oxidized/reducing agent and that H_2O was the reduced/oxidizing agent. Can someone explain to me why this is not oxidation-reduction reaction?
What is this balanced equation?
MnO4−(aq) +
I−(aq) I2(s) +
MnO2(s)
I got 2MnO4-(aq) +
6I-(aq) +
4H2O(l) ⇌ 3I2(s)
+ 2MnO2(s) + 8OH-(aq)
but webassign is saying it's wrong.
edit: nevermind, figured it out. 2
MnO4-(aq) + 8
H+(aq) +
6I-(aq) ⇌ 3
I2(s) + 2 MnO2(s) + 4
H2O(l)
