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

If n is an integer, which conjecture is not true about 2n– 1? A. 2n– 1 is odd if n is positive. B. 2n– 1 is always even. C. 2n–

VladimirAG [237]

B.

Let's simply look at each conjecture and determine if it's true or false.

A. 2nâ€“ 1 is odd if n is positive: Since n is an integer, 2n will always be even. And an even number minus 1 is always odd. Doesn't matter if n is positive or not. So this conjecture is true.

B. 2nâ€“ 1 is always even: Once again, 2n will always be even. So 2n-1 will always be odd. This conjecture is false.

C. 2nâ€“ 1 is odd if n is even: 2n is always even, so 2n-1 will always be odd, regardless of what n is. So this conjecture is true.

D. 2nâ€“ 1 is always odd: 2n will always be even. So 2n-1 will always be odd. Once again, this conjecture is true.

Of the 4 conjectures above, only conjecture B is false. So the answer is B.

Darrel has 36 daisies and 54 roses. He wants to put an equal number of daisies and roses into vases. What is the GREATEST number

castortr0y [4]

Answer:

18 number of daisies and 18 number of roses

Step-by-step explanation:

We are told Darrel has 36 daisies and 54 roses.

And that He wants to put an equal number of daisies and roses into vases.

To get the equal number, it means we have to find the greatest common factor of 36 and 54.

Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36

Factors of 54 = 1, 2, 3, 6, 9, 18, 27, 54

From the factors of both 36 and 54, the greatest common factor to both of them is 18.

Thus, the GREATEST number of daisies and roses Darrel can put in each vase is 18 each

(9x+13)^2=49<br> Solve the quadratic equation given below.

Varvara68 [4.7K]

Answer:

x=(-2/3)

Step-by-step explanation:

(9x+13)^2=49

√(9x+13)^2=√49

9x+13=7

9x+13-13=7-13

9x=-6

9x÷9=-6/9

x=-6/9

-6/9=-2/3
