Answer:
% (COOK)2H2O = 37.826 %
Explanation:
mix: (COOK)2H2O + Ca(OH)2 → CaC2O4 + H2O
∴ mass mix = 4.00 g
∴ mass (CaC2O4)H2O = 1.20 g
∴ Mw (COOK)2H2O = 184.24 g/mol
∴ Mw (CaC2O4)H2O = 146.12 g/mol
∴ r = mol (COOK)2H2O / mol (CaC2O4)H2O = 1
- % (COOK)2H2O = (mass (COOK)2H2O / mass Mix) × 100
⇒ mass (COOK)2H2O = (1.20 g (CaC2O4)H2O)×(mol (CaC2O4)H2O / 146.12 g (CaC2O4)H2O)×(mol (COOK)2H2O/mol (CaC2O4)H2O)×(184.24 g (COOK)2H2O/mol (COOK)2H2O)
⇒ mass (COOK)2H2O = 1.513 g
⇒ % (COOK)2H2O = ( 1.513 g / 4 g )×100
⇒ % (COOK)2H2O = 37.826 %
all of the absorbed energy is converted to kinetic energy
Explanation:
When a gas is heated, all of the absorbed energy is converted to kinetic energy. This is because, according to the kinetic theory of gases, the average kinetic energy of gases is directly proportional to temperature.
- As the gas absorbs more heat, the potential energy it carries converted to kinetic energy.
- Potential energy is the energy at rest of a body
- Kinetic energy is the energy due to the motion of the particles of a medium.
- As more heat is added to a body, the kinetic energy continues to increase significantly.
- Eventually, all the absorbed energy is converted to kinetic energy as the gas expands more.
