Heterogeneous Mixtures aren't uniform and are separated in the mixture. They are usually more easily able to be separated. An example is milk and cereal. The cereal isn't uniform because the milk and cereal still are separated and have their own identities. (You can easily just remove cereal from milk using a strainer)
Homogeneous Mixtures are uniform in composition and the multiple elements have become one solution. These mixtures are hard to separate into their components. An example is tap water because it contains water as well as various minerals that can only be separated by performing chemical reactions.
Answer:
HCl(aq) + KOH(aq) —> KCl(aq) + H2O(l)
Explanation:
Aqueous solution of HCl and aqueous solution of KOH react as follow:
HCl(aq) + KOH(aq) —>
In solution, HCl and KOH will dissociates as follow:
HCl —> H+ + Cl-
KOH —> K+ + OH-
During the reaction, a double displacement reaction occur as shown below:
H+ + Cl- + K+ + OH- —> K+Cl- + H+OH-
The elemental equation is given below:
HCl(aq) + KOH(aq) —> KCl(aq) + H2O(l)

A)
Each mole of Rb₃PO₄ will release:
3 moles of Rb⁺
1 mole of PO₄⁻³
So a total of 4 moles of ions are released per mole.
If there are 0.5 moles, 2 moles of ions will be released.
B)
Each mole of Cr₂(SO₄)₃ will release:
2 moles of Cr⁺³
3 moles of SO₄⁻²
So a total of 5 moles of ions are released per mole.
When there are 0.5 moles, 2.5 moles of ions will be released.
Answer:
400 mg
Explanation:
Given:
A woman with is told by her doctor to take 1,000 mg of calcium carbonate.
Question asked:
How many mg of calcium are in this 1,000 mg regimen of calcium carbonate?
Solution:
As we know:
<em>Amount of elemental calcium in a medicine containing calcium carbonate = 40%</em>
As here doctor prescribed 1000 mg of calcium carbonate to be taken by the woman increasing intake of calcium-containing foods in her diet and including regular weight-bearing exercise, hence amount of elemental calcium in 1,000 mg regimen of calcium carbonate will be,
Therefore, 400 mg of calcium are in this 1,000 mg regimen of calcium carbonate.
