.Florida phosphate accounts for ___ of the world's fertilizer supply?Immersive Reader
Stells [14]

Answer: 25%

Explanation: According to the Florida Industrial and Phosphate Research Institute, Florida’s phosphate mining  accounts for about 75% of the phosphate used in the United States, as well as about 25% phosphate used around the world.  Although first mined in England in 1847, and used as fertilizer, In  1881,  a civilian employee, J Francis Le Baron discovered Phosphate pebbles in peace river, and then, a hard rock phosphate district was discovered in north central Florida after that which began the Phosphate mining industry in Florida. Phosphorus rock  supplies the phosphorus element in the fertilizer mix of nitrogen-phosphorus-potassium that is used as fertilizer to aid in growth of plants.

What is the shortest half life
N76 [4]

Answer:

Hey!

Your answer is element A

Explanation:

Using the graph, the element A's emission of radioactive particles ends approximately after 6 years...

A HALF-LIFE IS "HALF" OF THAT TIME PERIOD!

So if the radiation goes for 6 years the half-life is 6 divided by two which gives you 3 years!

The rest however have a longer half-life...

Because they all end at 14 yrs so their half-life in 7 years!

HOPE THIS HELPS!!

Calculate the pH of a solution that is 0.235M benzoic acid and 0.130M sodium benzoate, a salt whose anion is the conjugate base
lesantik [10]

Hello!

We have the following data:

ps: we apply Ka in benzoic acid to the solution.

[acid] = 0.235 M (mol/L)

[salt] = 0.130 M (mol/L)

pKa (acetic acid buffer) =?

pH of a buffer =?

Let us first find pKa of benzoic acid, knowing that Ka (benzoic acid) = 6.20*10^{-5}

So:

pKa = - log\:(Ka)

pKa = - log\:(6.20*10^{-5})

pKa = 5 - log\:6.20

pKa = 5 - 0.79

\boxed{pKa = 4.21}

Now, using the abovementioned data for the pH formula of a buffer solution or (Henderson-Hasselbalch equation), we have:

pH = pKa + log\:\dfrac{[salt]}{[acid]}

pH = 4.21 + log\:\dfrac{0.130}{0.235}

pH = 4.21 + log\:0.55

pH = 4.21 + (-0.26)

pH = 4.21 - 0.26

\boxed{\boxed{pH = 3.95}}\end{array}}\qquad\checkmark

Note:. The pH <7, then we have an acidic solution.

I Hope this helps, greetings ... DexteR! =)
