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.

Na=1. Na = 1

so balance

and it would be

Alcl3 + 3Na → Al + 3NaCl

Nat2105 [25]

The answer is: Survival of the form that will leave the most copies of itself in successive generations.

"Survival of the fittest" is a phrase that originated from Darwinian evolutionary theory.

This is example of natural selection and adaptation.

Genetic variation is important to the population's ability to survive in different situations that affect natural selection.  

The environment is constantly changing and different alleles are favored.
