The heat released when 3.600 mol of NaOH is dissolved in water will depend on the enthalpy change of the dissolution process. This value is typically around -44 kJ/mol for NaOH in water. Therefore, the total heat released would be -44 kJ/mol * 3.600 mol = -158.4 kJ.
This value is 73,12 kJ.
The heat required to evaporate 1 liter of water at 100 degrees Celsius is known as the latent heat of vaporization of water, which is approximately 2260 kJ/kg. Since the density of water is about 1000 kg/m³, the heat required would be around 2260 kJ.
2200 kj
To convert 200 kJ to calories, you can multiply it by 0.239 to get approximately 47.8 calories.
For water vapours, 286 kJ/mol.
The water heat of vaporization is 40,65 kJ/mol.
The amount of energy given off when 17.0 mol of water is frozen can be calculated by multiplying the number of moles by the heat of fusion. Energy = 17.0 mol * 6.01 kJ/mol = 102.17 kJ.
The heat released when 3.600 mol of NaOH is dissolved in water will depend on the enthalpy change of the dissolution process. This value is typically around -44 kJ/mol for NaOH in water. Therefore, the total heat released would be -44 kJ/mol * 3.600 mol = -158.4 kJ.
The heat required to melt 1 mol of ice is 6.01 kJ, which is equivalent to 18 g of ice. Since you have 54.0 g of ice, which is 3 times the amount in 1 mol, you would need 3 times the heat, totaling 18.03 kJ to melt the ice.
2260 kj/kg X 0.086 kg = 194 kj The heat of vaporization for water is 2260 kj/kg at 1 atmosphere pressure.
The energy required to vaporize water at 100°C is known as the latent heat of vaporization, which is 2260 kJ/kg. Therefore, to vaporize 2kg of water at 100°C, the energy required would be 2260 kJ/kg x 2kg = 4520 kJ.
1878 kJ is 448.6 calories.
This value is 73,12 kJ.
The needed heat is 2 258 kJ.
The heat required to evaporate 1 liter of water at 100 degrees Celsius is known as the latent heat of vaporization of water, which is approximately 2260 kJ/kg. Since the density of water is about 1000 kg/m³, the heat required would be around 2260 kJ.
The energy needed to melt ice is given by the formula Q = m * L_f, where Q is the energy required, m is the mass of water, and L_f is the heat of fusion of water (334 J/g). Converting 334 J/g to kJ/g gives 0.334 kJ/g. Multiplying these together, we find that 183.3 g of water will require 61.21 kJ of energy to melt at 0°C.
