Answer:
A. Strong Acid Strong Base
D. ... 100%
Explanation:
The reaction of hydrobromic acid and sodium cyanide is a strong acid-strong base reaction. In solution, sodium cyanide functions as a strong base and reacts violently with strong acids. For strong acid- strong base reaction, the extent of reaction is usually 100%.
The molecular reaction equation is
NaCN(aq) + HBr(aq) ---------> NaBr(aq) + HCN(aq)
Ionically:
H3O+(aq) + CN- (aq) ----------> HCN(aq) +H2O (l)
HCN(aq) is a weak acid.
When vinegar and baking soda are mixed, a new chemical called carbonic acid is made. This carbonic acid immediately decomposes into carbon dioxide gas. When you mix the vinegar and baking soda, it's the carbon dioxide gas that makes the bubbles.
