They have a different amount of neutrons.
When dealing with making diluted solutions from concentrated solutions, we can use the following formula
c1v1 = c2v2
where c1 and v1 are the concentration and volume of the concentrated solution respectively.
c2 and v2 are the concentration and volume of the diluted solution respectively
substituting these values in the above formula,
20 mL x 0.200 M = C x 250.0 mL
C = 0.0160 M
Answer:
How does a balanced chemical equation verify the law of conservation of matter?
According to the Law conservation of matter
Mass can neither be created nor destroyed in a chemical reaction. That is, the total mass of the elements present in the products of a chemical reaction has to be equal to the total mass of the elements present in the reactants. In other words, the number of atoms of each element remains the same, before and after a chemical reaction. Hence, we need to balance the skeletal chemical equation.
The answer is b.volleyball
Answer:
0.015 M
Explanation:
Let's consider the solution of silver (I) sulfate.
Ag₂SO₄(s) ⇄ 2 Ag⁺(aq) + SO₄²⁻(aq)
In order to find the solubility (S) of silver (I) sulfate, we will use an ICE chart.
Ag₂SO₄(s) ⇄ 2 Ag⁺(aq) + SO₄²⁻(aq)
I 0 0
C +2S +S
E 2S S
The solubility product (Ksp) is:
Ksp = 1.4 × 10⁻⁵ = [Ag⁺]².[SO₄²⁻] = (2S)².S = 4S³
S = 0.015 M
