Answer:
BaCl2(aq) + K2CrO4(aq) = BaCrO4(s) + 2KCl(aq).
Explanation:
A base is an H⁺ acceptor, whereas an acid is an H⁺ donor. Acidic chemicals are typically recognized by their sour flavor.
Any hydrogen which contains a compound capable of giving a proton to another material is described as an acid. An ion and molecule that can receive a hydrogen ion from that of an acid is known as a base. Acidic chemicals are typically recognized by their sour flavor.
In essence, an acid is a substance that has the capacity to donate an H⁺ ion plus maintain its energetic favorability even after losing an H⁺ ion. It is well known that acids may change blue litmus into red. Bases, on the other hand, have a slick consistency and a bitter flavor. A base is an H⁺ acceptor, whereas an acid is an H⁺ donor.
Therefore, a base is an H⁺ acceptor, whereas an acid is an H⁺ donor.

Answer:
The theoretical yield of copper is 79.6281 g
Explanation:
Moles of copper sulfate =
According to reaction 1 mol of copper sulfate gives 1 mol of copper .
Then 1.2530 mol of copper sulfate will gives :
of copper .
Mass of 1.2530 mol of copper :
1.2530 mol × 63.55 g/mol = 79.6281 g
The theoretical yield of copper is 79.6281 g
(2) 35.0% (4) 60.0%
Answer:
The correct option is (2) 35.0%
Explanation:
If we want to calculate the percent composition by mass of nitrogen in NH4NO3 we first need to calculate the mass of nitrogen in one mole of NH4NO3.
Because of the molecular form of NH4NO3 (it has 2 ''N'') we know that one mole of NH4NO3 contains 2 moles of N.
The molar mass of N (nitrogen) is
This means that 1 mole of N contains 14.0067 grams of N.
Because we have 2 moles of N ⇒
We know that in 1 mole of NH4NO3 we have 2 moles of N(28.0134 g of N).
To calculate the percent composition by mass of nitrogen we need to divide the mass of nitrogen in one mole of NH4NO3 by the mass of one mole of NH4NO3 and then multiply it by 100.
We know that in 1 mole of NH4NO3 there are 80.0 g of NH4NO3 (Because of the molar mass data) ⇒
% ≅ 35.0%
We find that the percent composition by mass of nitrogen in NH4NO3 is 35.0%
We conclude that the correct option is (2) 35.0%
