Answer:

141

Step-by-step explanation:

The interior angles of a polygon with <em>n</em> sides is 180(<em>n</em> - 2) and the polygon has 7 sides, so the sum of its interior angles is 180(7 - 2) = 180(5) = 900.

125 + (x + 7) + 107 + (x - 15) + x + 131 + 122 = 900

Combining like terms,

3x + 477 = 900

3x = 423

x = 141

kiruha [24]

Answer:

2.16 * (10^-5).

Step-by-step explanation:

5 = -log H+

5 = log (1 / H+)

1/ H+ = 10^5

H+ = 10^-5

In a similar fashion  the other brand has H+ of 10^-4.5.

So the difference in hydrogen ion concentration =  10^(-4.5) - 10^(-5)

= 2.16 * (10^-5).
