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!!

Measurements show that the ph of a particular lake is 4.0. What is the hydrogen ion concentration of the lake?

fomenos

Answer: Hydrogen ion concentration of the lake is $10^{-4}M$

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration. Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.

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

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

We are given:

pH = 4.0

Putting values in above equation, we get:

$4.0=-\log[H^+]$

$[H^+]=10^{-4.0}$

$[H^+]=10^{-4}$

Thus hydrogen ion concentration of the lake is $10^{-4}M$
