Answer:
Diatomic molecules are molecules composed of only two atoms, of the same or different chemical elements. The prefix di- is of Greek origin, meaning "two
Explanation:
The answer for the following answer is explained below.
The answer is NH_{4} ^{+}
Explanation:
Bronsted-Lowry acid :
It is a solution that donates protons, and is known as a proton donor.It donates protons in the form of hydrogen ion(
).This is reinforced by the definition of an acid ,which is a solution that has hydrogen ions.
In Bronsted-Lowry aci it must contain a hydrogen io that it can give up.When the acid gives a hydrogen ion,the charge of an acid decreases.
Here,
NH_{4} ^{+} loses one hydrogen ion and forms ammonia molecule.
So therefore the Bronsted-Lowry acid is NH_{4} ^{+}.
The correct answer is MgSO₄.7H₂O.
The hydrate of magnesium sulfate goes through dehydration due to action of heat. This procedure can be represented chemically as follows:
MgSO₄.XH₂O (5.018 g) = MgSO₄ (2.449 g) + XH₂O (2.569 g)
The number of moles of H2O evolved = 2.569 / molecular weight
= 2.569 / 18 = 0.1427
Number of moles of MgSO₄ produced after decomposition,
= 2.449 / molecular weight
= 2.449 / 120.37
= 0.0203
Now dividing both these numbers to obtain the mole ratio, which prevails between MgSO₄ and H₂O
For H2O = 0.1427 / 0.0203 = 7.02 or 7
Therefore, the formula for the hydrate is MgSO₄.7H₂O.
