Answer:
564100J (~ 565000J) of heat energy is required.
Explanation:
The enthalpy of vaporization of water is 2256.4J/g, meaning that 2256.4J of heat is required to convert 1 gram of water at 100 degrees Celcius to steam at 100 degrees Celcius.
In your case, we have 250g of water at 100C and we want to vaporize it to steam (also at 100C).
This requires ΔH = 2256.4(250) = 564100J of heat energy.

We are given the following data.amount of oxygen gas mixed=108 grams molar mass of oxygen gas 32 g/mol volume of c3h8ch8.
After an experiment, scientists write a Conclusion which summarizes their experiment and results.
Every electron shell, designated by "n", has a specific number of electron subshells. The shell number has values equivalent to natural numbers (1, 2, 3, 4...), while the subshells are s, p, d and f.
The subshell that does not exist within the third shell (n = 3) is the f subshell. The energy of the f subshell is too high and cannot be accommodated in the third shell.
