Bromine.
Oxygen, selenium, and sulfur are all in group 16 and have 6 valence electrons. Bromine is in group 17 and has 7 valence electrons. The closer to 8 (a full, stable octet) you get, the less likely the element is to react.
PH of solution will be greater than seven (pH>7), that means that solution is basic (<span>pH above </span>7<span> is a base, the higher the number, the stronger is the base).
</span>pH (potential of hydrogenis) is a measure of the hydrogen ion (H⁺) concentration of a solution. <span>Solutions with a pH less than 7 are acidic.</span>

Explanation:
The trapped carbon dioxide makes the dough rise, and the alcohol evaporates during the baking process. This is an irreversible chemical change, because by consuming the sugar, the yeast has created new substances
Ice, freezing, or melting then liquid evaporation or condensation, the vapor, deposition the ice again
