Which chemical reaction model is flawed? a. 4 c2 + s8 → 4 cs2 b. 2 fe + 3 cl2 → 2 fecl3 c. 2 na + cl2 → 2 nacl d. p4o10 + 6 h2o → 4 h3po4

The equation in option A appears to be flawed.

The left hand side of the first equation contains eight carbon atoms whereas the right hand side contains only four. This equation is thus not properly balanced.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
