An unknown blue liquid is found. When tested, it has high amounts of hydroxide ions and low amounts of hydronium ions. Is this an acid or a base?(1 point)
An acid because it has more hydroxide ions than hydronium ions.
An acid because it is a blue liquid.
.
A base because it has more hydroxide ions than hydronium ions.
A base because it is a blue liquid.
Use the following neutralization reaction to answer the question.
HC2H3O2+NaOH→NaC2H3O2+H2O
Which of the reactants is the acid?
(1 point)
NaOH because it releases a hydrogen.
cap n A cap o cap h because it releases a hydrogen.
HC2H3O2 because it releases a hydrogen.
cap h cap c sub 2 cap h sub 3 cap o sub 2 because it releases a hydrogen.

Which statement best describes the process of ocean acidification due to higher temperatures? (1 point)
The ocean absorbs carbon dioxide, which reacts with water to create acids. The acids cause an increase in hydroxide ions, increasing pH.
The ocean releases carbon dioxide, which reacts with water to create acids. The acids cause an increase in hydroxide ions, increasing pH.
The ocean releases carbon dioxide, which reacts with water to create acids. The acids cause an increase in hydronium ions, decreasing pH.
The ocean absorbs carbon dioxide, which reacts with water to create acids. The acids cause an increase in hydronium ions, decreasing pH.
How does a lower pH in the ocean impact marine life? (1 point)
The lower pH causes fish to reproduce at greater rates, increasing populations.
The lower pH causes fish to reproduce at greater rates, increasing populations.
The lower pH causes harm to predators and increases the population of prey.
The lower pH causes harm to predators and increases the population of prey.
The lower pH causes coral reefs to be weak and break, destroying marine habitats.
The lower pH causes coral reefs to be weak and break, destroying marine habitats.
The lower pH causes more carbon dioxide to be absorbed which increases plant life.
i just did it and its c,d,d,and a
The lower pH causes coral reefs to be weak and break, destroying marine habitats. Just like my jokes weaken and break friendships.
The correct answers are:
- A base because it has more hydroxide ions than hydronium ions.
- HC2H3O2 because it releases a hydrogen.
- The ocean absorbs carbon dioxide, which reacts with water to create acids. The acids cause an increase in hydronium ions, decreasing pH.
- The lower pH causes coral reefs to be weak and break, destroying marine habitats.
