You have 10 fish,5 drowned,3 came back to many fish do you have now?

An addition of acid increases the solubility of calcium phosphate because the hydrogen ions can easily dissociate and form salts. And example is from the reaction 3H2SO4 + Ca3(PO4)2 → 2H3PO4 + 3CaSO4. CaSO4 is the salt of sulfuric acid and calcium phosphate. 

Answer: Option (A) is the correct answer.

Explanation:

The process in which two or more small nuclei combine together to result in the formation of a larger nuclei is known as fusion.

In Sun, four hydrogen nuclei combine together to result in the formation of helium atom. This combining of small hydrogen nuclei to form a large helium nuclei represents fusion process occurring inside the Sun.

Thus, we can conclude that to power itself, the sun is constantly generating a nuclear reaction in its core, in which hydrogen nuclei are combined to form helium. This process is known as fusion.

Answer: -

Without the sun, life on earth would not exist. There would be no warmth, no plants, no animals, no night and day.

To power itself, the sun is constantly generating a nuclear reaction in its core, in which hydrogen nuclei are combined to form helium. This process is known as

A) Fusion

Fusion produces a lot of energy but very little radioactive waste.

Answer: b. ,

Explanation:

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.

For the given chemical equation:

Here, is accepting a proton, thus it is considered as a base and after accepting a proton, it forms which is a conjugate acid.

And, is losing a proton, thus it is considered as an acid and after loosing a proton, it forms which is a conjugate base.

Hence, the correct answer is b. ,
