Answer: The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. This means that they have more collisions with each other and the sides of the container and hence the pressure is increased.

Answer:
True
Explanation:
A pH of 7 is greater than basic but lesser than acidic. Therefore, it's neutral
Answer:
7923.6 g of (NH₄)₂SO₄ can be produced by this reaction
Explanation:
The reaction is:
2NH₃ (aq) + H₂SO₄(aq) → (NH₄)₂SO₄(aq)
In this reaction ratio is 1:1.
As the ammonia is in excess, the limiting reagent is the sulfuric acid.
So 1 mol of sulfuric can produce 1 mol of sulfate
Then, 60 moles of sulfuric must produce 60 moles of sulfate.
We convert the moles to mass:
60 mol . 132.06 g / 1mol = 7923.6 g
Yes,0. 49 is smaller than 0.72
Isotopes of the same element differ only in the number of neutrons an atom has. Its still the same element because the number of protons define an element. Just their neutrons and mass number is different.
