Point E is located at (-2, 2) and point F is located at (4-6). What is the distance between

Flauer [41]

Answer:

Explanation:

Given endpoints:

E (-2,2) and F(4, -6)

To find the distance between two points;

Use the expression below;

D = $\sqrt{(y_{2} - y_{1} )^{2} + (x_{2} - x_{1})^{2} }$

x₁ = -2,

x₂ = 4

y₁ = 2

y₂ = -6

Insert the parameters and solve;

D = $\sqrt{(-6 - 2 )^{2} + (4 -+ 2)^{2} }$

D = $\sqrt{64+ 36 }$ = 10

The normal range of the pH of blood is between 7.35 and 7.45; variations beyond this range have significant health implications.

patriot [66]

Answer:

The hydrogen ion concentrations associated with these pH value 7.35 is $4.5\times 10^{-8} M$

The hydrogen ion concentrations associated with these pH value 7.45 is $3.6\times 10^{-8} M$ .

Explanation:

To calculate the pH of the solution, we use the equation:

$pH=-\log[H^+]$

We are given:

1) pH = 7.35

Putting values in above equation, we get:

$7.35=-\log[H^+]$

$[H^+]=4.467\times 10^{-8} M\approx 4.5\times 10^{-8} M$

The hydrogen ion concentrations associated with these pH value 7.35 is $4.5\times 10^{-8} M$

2) pH = 7.45

Putting values in above equation, we get:

$7.45=-\log[H^+]$

$[H^+]=3.548\times 10^{-8}M \approx 3.6\times 10^{-8} M$

The hydrogen ion concentrations associated with these pH value 7.45 is $3.6\times 10^{-8} M$ .

maxonik [38]

Sodium acetate contains both ionic and covalent bonds. In sodium acetate, there is ionic bond between sodium and acetate ions and there is covalent bond in the atoms that are bondeed to the carbon atoms. Hope this answers the question.
