Question

Kbr+h2so4=br2+so2+k2so4+h2o

Answer 1

2 KBr + 2 H2SO4 = Br2 + SO2 + 2 H2O + K2SO4

2 Br-I - 2 e-→ 2 Br0 (окисление)

SVI + 2 e- → SIV (восстановление)

Answer 2

The chemical equation you provided appears to be unbalanced. Let's balance it:

KBr + H2SO4 → Br2 + SO2 + K2SO4 + H2O

To balance the equation, we need to make sure that the number of atoms of each element is the same on both sides of the equation. Here's the balanced equation:

2KBr + H2SO4 → Br2 + SO2 + K2SO4 + 2H2O

Now, the equation is balanced. It shows that when potassium bromide (KBr) reacts with sulfuric acid (H2SO4), it produces bromine gas (Br2), sulfur dioxide (SO2), potassium sulfate (K2SO4), and water (H2O).
