Molecule C requires the least energy, Molecule B requires more, and Molecule A requires the most.
Explanation: Molecule C is made up of a triple bond, which requires the most energy to break. Molecule B is made up of a double bond which is not as strong as a triple bond therefore requiring less energy. Molecule A is made up of a single bond which is the least strong thus requiring the least amount of energy.
a precipitate is is an insoluble solid that forms when two solutions are combined and react chemically. The two clear colorless liquids is a chemical change because a different solid substance is formed
<span>35.0 mL of 0.210 M KOH
molarity = moles/volume
find moles of OH
do the same thing for: 50.0 mL of 0.210 M HClO(aq) but for H+
they will cancel out: H+ + OH- -> H2O
but you'll have some left over, pH=-log[H+]
pOH =-log[OH-]
pH+pOH =14</span>
