In accordance with the Le Chatelier's Principle, when the concentration of the aluminum increases then the equilibrium would shift to the right. It will produce more products since there are more reactants available and also collision is more frequent.
Answer:
Mass of paraffin that would be needed to collect the amount of energy as 4.73 x 10³ kg of water is 6.85 * 10³ kg
Explanation:
Specific heat capacity of paraffin, Cp = 2.90 J/g.°C = 2900 J/kg.°C
Specific heat capacity of water = 4.20 J/g.°C = 4200 J/kg.°C
Amount of heat energy that can be stored by 4.73 * 10³ kg of water heated through a degree rise in temperature can be calculated as below:
Using H = mCpθ where m is mass of substance, Cp is specific heat capacity and θ is temperature change
H = 4.73 * 10³ kg * 4200 J/kg.°C * 1°C
H = 19866000 J
Mass of paraffin that would be needed to collect the amount of energy as 4.73 x 10 3 kg of water for a degree rise in temperature is calculated as follows:
H = mCpθ
19866000J = m * 2900 J/kg.°C * 1°C
m = 19866000J / 2900 J/kg
m = 6850.34 kg = 6.85 * 10³ kg
Therefore, mass of paraffin that would be needed to collect the amount of energy as 4.73 x 10³ kg of water is 6.85 * 10³ kg
