Acidity is measured on the pH scale. The acidity of a substance is given by pH=−logH, where H is the concentration of Hydrogen i
frosja888 [35]

Answer:

[H^+] = Antilog[-6]

Step-by-step explanation:

Even though the question is incomplete, let us try to correctly derive the equation used to find the hydrogen ion concentration.

pH=−log[logH^+]

-pH = log[H^+]

[H^+] = Antilog[-pH]

Since pH =6

The equation is;

[H^+] = Antilog[-6]

Find the equation of the line use exact numbers
mart [117]

Answer:

y = -³/2x + 3

Step-by-step explanation:

To find the equation of the line in slope-intercept form, y = mx + b, we need to finder the slope (m) and the y-intercept (b).

✔️Slope (m) = ∆y/∆x

Using two points on the line, (0, 3) and (2, 0),

Slope = (0 - 3)/(2 - 0) = -3/2

Slope (m) = -³/2

✔️y-intercept (b) = 3 (this is the y-cooordinate of the point where the line intercepts the y-axis)

✔️To write the equation, substitute m = -³/2 and b = 3 into y = mx + b

This:

y = -³/2x + 3
