<u>Answer:</u> The amount of p-toluidine hydrochloride contained is 2.4 moles.
<u>Explanation:</u>
To calculate the number of moles for given molarity, we use the equation:
Molarity of p-toluidine hydrochloride solution = 0.167 M
Volume of solution = 70. mL
Putting values in equation 1, we get:
Hence, the amount of p-toluidine hydrochloride contained is 2.4 moles.
Answer:
Decomposition
Explanation:
A decomposition reaction is when a compound breaks down into simpler substances.
in our case Ammonium hydroxide requires an input of energy to obtain Ammonia gas and water.
You can find it by adding the standard atomic masses of the constituent atoms.
The generic reaction a + b = c, represents a synthesis or combination reaction, which is a kind of chemical reaction.
<h3>What is a synthesis reaction?</h3>
A synthesis, or combination reaction, is a kind of reaction in which two substances combine to form a bigger molecule.
The generic reaction is:
a + b = c
Some common synthesis reactions are:
- Two elements combine to form a compound.
Fe + S = FeS
- One element and one compound combine to form a compound.
O₂ + 2 SO₂ = 2 SO₃
- Two compounds combine to form another compound.
CaO + CO₂ = CaCO₃
In all the examples above, we can verify that the substances (elements or compounds) combine with each other to form another substance (product).
The generic reaction a + b = c, represents a synthesis or combination reaction, which is a kind of chemical reaction.

There are 3.98 × 10^23 atoms of oxygen in the sample.
Given that;
1 mole of Mo(NO3)6 contains 6.02 × 10^23 atoms of Nitrogen
x moles of Mo(NO3)6 contains 2.22 x 10^22 atoms of nitrogen
x = 1 mole × 2.22 x 10^22 atoms/6.02 × 10^23 atoms
x = 0.0368 moles
The number of oxygen atoms in the sample is given by; 0.0368 × 6.02 × 10^23 × 18
Therefore, there are 3.98 × 10^23 atoms of oxygen in the sample.
