The equation for the pH of a substance is pH = –log[H+], where H+ is the concentration of hydrogen ions. What is the approximate

Mademuasel [1]

Answer:

pH = 3.3

Step-by-step explanation:

pH is given by the formula; pH = –log[H+]

The concentration of hydrogen ions is 5.0 × 10–4 moles per liter.

Therefore;

pH = - log₁₀(5.0 × 10^–4)

= -( - 3.301)

= 3.301

Thus;

The approximate pH will be; 3.3

Graph the equation y equals negative 3x - 4 by plotting points y = -3x - 4

ivann1987 [24]

Explanation:

We need to find two points that are solutions to the equation.

So, if x = 0, then:

y = -3x - 4

y = -3(0) - 4

y = 0 - 4

y = -4

And, if x = 1, then:

y = -3(1) - 4

y = -3 - 4

y = -7

Answer:

Then, the line passes through the points (0, -4) and (1, -7). So the graph of the equation is:
