There are certain processes in nature that produce many of these radioactiveisotopes. For instance, some radioactive nitrogen is produced in the atmosphere when high energy cosmic radiation from the sun hits the earth. Other radioactiveisotopes are only available by artificial production. good luck

How did scientists discover that Earth's outer core is liquid?

Sholpan [36]

They discovered this since S waves don’t travel through the earth but P waves do. P waves tend to travel faster than S waves in speed, 1&14km/s vs 1&8km/s

What are the hydronium and hydroxide ion concentrations in a solution whose ph is 6.52?

erica [24]

A solution with a pH of 6.52 has a hydronium ion concentration of 3.02x10-7 mol/L and a hydroxide ion concentration of 3.31x10-8 mol/L.

The hydronium ion concentration of a solution can be calculated from pH by using $10^{-pH}$ . For a pH of 6.52, hydronium ion concentration is 3.02x10-7 mol/L.

The concentration of hydroxide ions can be determined by identifying the value of pOH. The sum of pOH and pH is equal to 14, which is based on the negative logarithm of the ion-product constant of water. At a pH of 6.52, pOH is equal to 7.48.

The relationship between pOH and hydroxide ion concentration is the same as the relationship between pH and hydronium ion concentration. With this, the hydroxide ion concentration at pOH of 7.48 is $10^{-7.48}$ or 3.31x10-8 mol/L.
