Answer: D. it only partially dissociates in solution.

Explanation:

Strong acid is defined as the acid which completely dissociates when dissolved in water. They have low pH. These releases $H^+$ ions in their aqueous states.

$HNO_3(aq.)\rightarrow H^+(aq.)+NO_3^-(aq.)$

Weak acid is defined as the acid which does not completely dissociates when dissolved in water. They have high pH. These releases $H^+$ ions in their aqueous states.

$CH_3COOH\rightleftharpoons CH_3COO^-+H^+$

Thus the correct option is it only partially dissociates in solution.

What is the slope of the line?

pychu [463]

Answer:

The slope of the line is $-\frac{10}{7}$ .

Explanation:

The slope of the line ( $m$ ) is the change in dependent variable ( $y$ ) divided by the change in independent variable ( $x$ ):

$m = \frac{y_{f}-y_{o}}{x_{f}-x_{o}}$ (1)

If we know that $(x_{o}, y_{o}) = (0, 2)$ and $(x_{f}, y_{f}) = (1.4, 0)$ , then the slope of the line is:

$m = \frac{0-2}{1.4-0}$

$m = -\frac{10}{7}$

The slope of the line is $-\frac{10}{7}$ .
