You have 42.5 g of water.
42.5g H20 / 18.02 g H2O
(2.358 moles H2O)*(6.02 Kj/1mole H2O)
= 14.1981 Kj
=14.2 kJ
When 42.5 grams of water freezes, it releases 1784.5 Joules of energy. This energy is given off as the water molecules slow down and form a more ordered solid structure during the freezing process.
The energy released when water freezes is about 334 J/g. Therefore, for 65.8g of water, the energy released during freezing would be approximately 22,000 J.
To calculate the energy released when 1.56 kg of ethanol freezes, first convert the mass of ethanol to moles using its molar mass. Then, use the heat of fusion of ethanol to determine the energy released using the formula: Energy released = moles of ethanol x heat of fusion.
When hydrogen and oxygen gases react to produce water, 285.5 kJ of energy is released per mole of water formed. To calculate the energy released when 15.0g of water is produced, you first need to determine the number of moles of water produced, then multiply by 285.5 kJ/mol to find the total energy released.
The amount of energy generated from freezing 2.5g of water can be calculated using the specific heat capacity of water and the heat of fusion for water. The energy released would be equal to the heat of fusion of water (334 J/g) multiplied by the mass of water (2.5g). By multiplying these values, you can determine the total energy released during the freezing process.
2.5 g 1 mol/18.02 g (-285.83) kJ/mol
347 J/g.K or 83 cal are released.
The energy released when water freezes is about 334 J/g. Therefore, for 65.8g of water, the energy released during freezing would be approximately 22,000 J.
Fresh water freezes much much quicker.
To calculate the energy released when 1.56 kg of ethanol freezes, first convert the mass of ethanol to moles using its molar mass. Then, use the heat of fusion of ethanol to determine the energy released using the formula: Energy released = moles of ethanol x heat of fusion.
The heat of fusion of ethanol is 4.94 kJ/mol-167 - 168 KJ
For water vapours, 286 kJ/mol.
Zero C
When water freezes, it turns into what we call ice. ice is a solid. no offense, but um stupid question.
The energy released when water is condensed from water vapor is known as the heat of condensation. This process releases about 40.7 kJ of energy per mole of water condensed. To calculate the energy released when 6.0 g of water is condensed, you would first convert grams to moles and then use the molar heat of condensation to find the total energy released.
When water freezes, it expands as it turns into ice. This expansion causes the volume of the water balloon to increase, which can lead to the balloon bursting if the ice takes up too much space.
The energy released when 6 grams of water is condensed from water vapor is equal to the heat of vaporization of water. This is approximately 2260 joules per gram. So, for 6 grams of water, the total energy released would be around 13,560 joules.
The energy released when condensing water vapor is known as the heat of condensation. It takes 2260 Joules of energy to condense 1 gram of water vapor. So, for 6.0 grams of water vapor, the energy released would be 6.0 grams * 2260 Joules/gram = 13,560 Joules.
