Answer the following questions:
1. What is observed when a solution of potassium iodide is added to a solution of lead nitrate? Name the type of reaction. Write a balanced chemical equation to represent the above chemical reaction.
2. Write a balanced chemical equation for the process of photosynthesis and the conditions of reaction giving physical state of all substances.
3. Identify the type of reaction from the following equations:
a. \(CH_4\) + \(2O_2\) → \(CO_2\) + \(2H_2O\)
b. \(Pb(NO_3)_2\) + \(2KI\) → \(PbI_2\) + \(2KNO_3\)
c. \(CaO\) + \(H_2O\) → \(Ca(OH)_2\)
d. \(CuSO_4\) + \(Zn\) → \(ZnSO_4\) + \(Cu\)
a. \(CH_4\) + \(2O_2\) → \(CO_2\) + \(2H_2O\)
b. \(Pb(NO_3)_2\) + \(2KI\) → \(PbI_2\) + \(2KNO_3\)
c. \(CaO\) + \(H_2O\) → \(Ca(OH)_2\)
d. \(CuSO_4\) + \(Zn\) → \(ZnSO_4\) + \(Cu\)
