Answer:

see explanation

Step-by-step explanation:

Euler's formula states that the sum of the number of faces (F) and the number of vertices (V) of a polyhedra is equivalent to two more than the number of its edges (E) , that is

F + V = E + 2

The approximate molar concentration of several chemicals are given. Find the pH of each use the calculator and round to the near

mojhsa [17]

Answer:

$pH = 13$ --- Oven Cleaner

$pH = 6.2$ --- Water

$pH =7.4$ --- Blood

$pH = 2.2$ --- Vinegar

Step-by-step explanation:

The given molar concentration are:[Missing from the question]

Oven Cleaner: [h+] = $10^{-13}$

Water: [h+] = $0.0000007$

Blood: [h+] = $0.00000004$

Vinegar: [h+] = $0.0063$

Required

Determine the pH

pH is calculated using:

$pH = -\log(h+)$

So, we have:

Oven Cleaner:

$pH = -\log(10^{-13})$

Using a calculator, we have:

$pH = 13$

Water:

$pH = -\log(0.0000007)$

Using a calculator, we have:

$pH = -1*-6.2$

$pH = 6.2$

Blood:

$pH = -\log(0.00000004)$

Using a calculator, we have:

$pH = -1 * -7.4$

$pH =7.4$

Vinegar:

$pH = -\log(0.0063 )$

Using a calculator, we have:

$pH = -1 * -2.2$

$pH = 2.2$
