Orange juice is a common breakfast drink that contains citric acid. If the hydronium ion concentration is 3.4 × 10-4 in orange j

Lelu [443]

Answer:

3.5

Step-by-step explanation:

Given : the hydronium ion concentration is $3.4*10^{-4}$ in orange juice

To Find: what is the pH?

Solution :

Definition of pH : pH is the negative log of the molar hydrogen ion concentration

Formula of pH : - log [H+]

Since we are given H+ = $3.4*10^{-4}$

So, substituting this value in formula :

$pH = - log [3.4*10^{-4}]$

$pH = - log [3.4*0.0001]$

$pH = - log [0.00034]$

$pH = 3.468$

pH = 3.468≈3.5

Thus the pH is 3.5

What is the value of x

RideAnS [48]

Answer:

x=5

Step-by-step explanation:

We can use the Triangle Angel Bisector Theorem

AB 2x-1

----------= --------------

AC 3x

9 2x-1

----------= --------------

15 3x

Using cross products

3x*9 = 15*(2x-1)

Distribute

27x = 30x-15

Subtract 30x from each side

27x-30x = 30x-30x-15

-3x = -15

Divide by -3

-3x/-3 =-15/-3

x =5
