In most atoms, electrons occupy a zone exterior to the nucleus.
The activation energy in the
diagram is 43.8 kcal/ mole, letter C. You have to note that activation energy
is the energy needed for the reaction to occur and produce products. Therefore,
the spike after H2 and I2 is reacted is the activation energy of the reaction.
The chemical formula of the solute is NaNO3. The mass of this is 1.4*85=119 g. The boiling point of the solution is higher than water. The molarity of this solution is 1.4/2=0.7 M.
The simplest ratios compare only two values, but ratios comparing three or more values are also possible. In any situations in which two or more distinct numbers or quantities are being compared, ratios are applicable. By describing quantities in relation to each other, they explain how chemical formulas can be duplicated or recipes in the kitchen expanded.
