Answer 2

1. AgNO3 + KBr = AgBr + KNO3: This is a double displacement reaction, also known as a precipitation reaction. Silver nitrate (AgNO3) reacts with potassium bromide (KBr) to form silver bromide (AgBr) and potassium nitrate (KNO3).

2. PbO + SiO2 = PbSiO3: This is a combination reaction. Lead(II) oxide (PbO) reacts with silicon dioxide (SiO2) to form lead silicate (PbSiO3).

3. 2KBr + Cl2 = 2KCl + Br2: This is a redox reaction, specifically a displacement reaction. Potassium bromide (KBr) reacts with chlorine gas (Cl2) to form potassium chloride (KCl) and elemental bromine (Br2).
