How much energy is released when hydrogen and oxygen gases react to produce 15.0gg of water?
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.
How much hydrogen would be required to produce 7.4 mol of water?
To produce 1 mole of water, you need 2 moles of hydrogen. Therefore, to produce 7.4 moles of water, you would need 2 * 7.4 = 14.8 moles of hydrogen.
How much energy is released when 42.5 of water freezes?
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
How much energy is absorbed when 356 g of ethanol 46.0 g molboils The heat of vaporization of ethanol is 38.6 kJ mol?
To calculate the energy absorbed, first convert the mass of ethanol from grams to moles. 356 g of ethanol is 356/46.0 = 7.74 moles. Then, multiply the moles of ethanol by the heat of vaporization: 7.74 mol * 38.6 kJ/mol = 298.56 kJ of energy absorbed.
How much C4H10 would you need to create 20 ml of water in a combustion?
Pure combustion of butane has the reaction 2 C4H10 + 13 O2 equals8 CO2 + 10 H2O. This means that every mole of butane produces 5 moles of water. 20 ml of water equals 1.11 moles, so .222 moles of butane are needed, or 5.17 liters.
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
Do moles drink?
yes moles do drin water but not much
How much does 4.04 moles of water weigh?
72.8grams
How would you find out how much 12.4 moles of water weigh?
Multiply moles by molecular mass of water (18), gives you 223.8g. Remember this formula: Number of moles = mass / molecular mass
How much can energy is released when 6.0 g of water is condensed from water vapor?
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.
How much water, in the form of H2O molecules, is present in 6 moles of a substance?
6 moles of a substance contain about 3.6 x 1024 water molecules.
Does baking soda and water sting on moles?
Yes,but not too much...
How much energy is released when hydrogen and oxygen gases react to produce 15.0gg of water?
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.
How much energy is required to decompose 765 g of PCl3 in 4PCl3---P4 plus 6Cl2?
The balanced chemical equation is 4PCl3 → P4 + 6Cl2. The molar mass of PCl3 is 137.33 g/mol. To calculate the energy required, first find the moles of PCl3 (765 g / 137.33 g/mol), then use the stoichiometry from the balanced equation to convert moles of PCl3 to moles of P4, and finally use the enthalpy values for each reaction to determine the total energy required. The enthalpy values for each reaction can then be multiplied by the number of moles of each substance in the reaction to find the total energy required for the reaction.
How do you calculate how much energy in kJ do 3.0 moles of photons all with a wavelength of 655 nm contain?
The energy is 18,263.10e4 joules.
How much energy is given off when 17.0 mol of water is frozen The heat of fusion for water is 6.01 kJ molb?
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.
How much does 10 moles of water weigh?
As the molar mass of water is 18 g/mol (1*2 H + 16 O) 10 moles*18 g/mole=180 grams.
