Each mole of barium sulfate releases equal moles of barium ions and sulfate ions. Let the concentration of one substance be x. Thus:
Ksp = [Ba⁺²][SO₄⁻²]
1.1 x 10⁻¹⁰ = (x)(x)
x = 1.05 x 10⁻⁵
The answer is A.
4.1 is acidic on the Ph scale
Answer:
(C)Calcium oxide reacts sulfuric acid
Explanation:
Answer : The specific heat of the metal is,
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of metal = ?
= specific heat of water =
= mass of metal = 50.0 g
= mass of water = 125 g
= final temperature of mixture =
= initial temperature of metal =
= initial temperature of water =
Now put all the given values in the above formula, we get
Therefore, the specific heat of the metal is,
This is the answer i for when I worked it out, it may be right and it may be wrong. I am currently in Pre-AP chem and we just learned this this week and I am in the same boat as you ahaha
