Three blocks of metal at the same temperature are placed on a hot stove. Their specific heat capacities are listed below.Rank th
1 answer:
Answer:
Copper>Steel>Aluminium
Explanation:
Hello,
Since the heat capacity accounts for the required heat to increase by 1°C, 1 kg of the metal, copper is the one that has the lower heat capacity, it means that it requires the least amount of energy to warm up (increase its temperature), this could be substantiated via the mathematical definition of heat capacity:
Solving for :
It means that the lower the heat capacity, the higher the final temperature.
Best regards.

The empirical formula of the organic compound is =
Explanation:
At STP, 1 mole of gas occupies 22.4 L of volume.
Moles of gas at STP occupying 2.0 L = n
Moles of carbon in 0.08920 mol = 1 × 0.08920 mol = 0.08920 mol
Moles of gas at STP occupying 3.0 L = n'
Moles of hydrogen in 0.1339 moles of water vapor = 2 × 0.1339 mol = 0.2678 mol
Moles of gas at STP occupying 1.0 L = n''
Moles of sulfur in 0.04464 mol = 1 × 0.04464 mol = 0.04464 mol
Moles of carbon , hydrogen and sulfur constituent of that organic compound .
Moles of carbon in 0.08920 mol = 1 × 0.08920 mol = 0.08920 mol
Moles of hydrogen in 0.1339 moles of water vapor = 2 × 0.1339 mol = 0.2678 mol
Moles of sulfur in 0.04464 mol = 1 × 0.04464 mol = 0.04464 mol
For empirical; formula divide the least number of moles from all the moles of elements.
carbon =
Hydrogen =
Sulfur =
The empirical formula of the organic compound is =
