Answer:<span> a) the process for the first ionization energy
</span>
<span>Every time you take a electron you're requiring more and more energy. Expelling the first one
will require less energy than expelling the second and the second will
require less than the third, and so on.
When you take the first one, the atom becomes positive and with that the negative forces of the electron will be more attracted to the positive
charge. The more electrons that are lost, the
more positive this ion will become, causing it to be more difficult to separate the
electrons from the atom.

a question that can be answered wity a hypothesis is a question a scientist can answer
Denitrification is part of the nitrogen cycle
<span>C represents the displacement ONLY if it is the VECTOR arrow from P to W.
Usually if the arrow on the diagram has JUST a letter listing, that letter stands for the SIZE or LENGTH of the VECTOR arrow. In order to have the letter represent the VECTOR, itself, it must have a symbol of a "half arrow" placed above it.</span>
<h2>Answer:</h2>
<em>8.67kJ/mol</em>
<h2>Explanations</h2>
The formula for calculating the amount of heat absorbed by the water is given as:
Determine the moles of KI
Since heat is lost, hence the enthalpy change of the solution will be negative that is:
Determine the enthalpy of solution in kJ•mol-1
Hence the enthalpy of solution in kJ•mol-1 for KI is 8.67kJ/mol
