Chemistry

Chemical Reactions

Balancing Chemical Equations

1. Write the unbalanced equation:

   • Example: $C_3H_8 + O_2 \rightarrow CO_2 + H_2O$

2. Balance the equation:

   • Balance carbon atoms first.
   • Then balance hydrogen atoms.
   • Finally, balance oxygen atoms.
   • Balanced equation: $C_3H_8 + 7O_2 \rightarrow 3CO_2 + 4H_2O$

3. Balance the equation:

   • Balance oxygen atoms.
   • Finally, balance oxygen atoms.
   • Balanced equation: $C_3H_8 + 7O_2 \rightarrow 3CO_2 + 4H_2O$

Types of Reactions

1. Combination Reaction:

   • Example: $2H_2 + O_2 \rightarrow 2H_2O$

2. Decomposition Reaction:

   • Example: $2H_2O_2 \rightarrow 2H_2O + O_2$

3. Single Displacement Reaction:

   • Example: $Zn + 2HCl \rightarrow ZnCl_2 + H_2$

4. Double Displacement Reaction:

   • Example: $AgNO_3 + NaCl \rightarrow AgCl + NaNO_3$

5. Combustion Reaction:

   • Example: $CH_4 + 2O_2 \rightarrow CO_2 + 2H_2O$

Stoichiometry

Mole Concept

• Mole (mol): The amount of substance containing as many particles (atoms, molecules, ions) as there are atoms in exactly 12 grams of carbon-12.
• Avogadro's Number: $6.022 \times 10^{23}$ particles per mole.

Molar Mass

• Molar Mass: The mass of one mole of a substance.
• Example: The molar mass of water ($H_2O$) is 18.015 g/mol.

Calculations

1. Moles to Mass:

   • Formula: $n = \frac{m}{M}$
   • Example: Calculate the number of moles of $H_2O$ in 18 grams of water.
     • $n = \frac{18.015 , \text{g}}{18.015 , \text{g/mol}} = 18.015 , \text{g/mol}$

2. Moles to Mass:

   • Formula: $m = n \times M$
   • Example: Calculate the mass of 18.015 g of water.
     • $m = 18.015 , \text{g/mol} = 18.015 , \text{g/mol}$

Thermochemistry

Enthalpy (H)

• Definition: The heat content of a system at constant pressure.
• Change in Enthalpy (ΔH): $ΔH = q_p$
• Change in Enthalpy (ΔH_2): $ΔH_2H_2 + q_1$
• Change in Enthalpy (ΔH_1): $ΔH_1H_1 + q_2$

Hess's Law

• Statement: The enthalpy change for a reaction is the same whether it occurs in one step or multiple steps.
• Equation: $\Delta H = q_p \Delta H_2$
• Equation: $\Delta H_2H_2 \Delta H_2 \Delta H_1$

Electrochemistry

Oxidation and Reduction

• Oxidation: Loss of electrons.
• Reduction: Gain of electrons.

Galvanic Cells

• Definition: A cell that converts chemical energy into electrical energy.
• Components:
  • Anode: Oxidation occurs.
  • Cathode: Reduction occurs.
  • Salt Bridge: Connects the two half-cells.

Nernst Equation

• Equation: $E = E^\circ - \frac{RT}{nF} \ln Q$
