A solution is when you have a solute and a solvent, for example, sugar and water. Since copper and silver are solids, they cannot physically be dissolved in each other. Think of it as a mix of granola and raisins. The silver is the granola and the copper is the raisins. Now, if silver were to be mixed with nitric acid, a liquid, it would be different.
Chemical Compounds, hope this helps.
Answer:
Combustion – substance reacts with oxygen often producing heat and light. Oxygen is ALWAYS one of the reactants. ... CH4 + 2O2 → CO2 + 2H2O Incomplete combustion – carbon monoxide and water.
Explanation:
It would be MnSO4
The (II) lets you know it’s the form with a 2+ charge and Sulfate has a 2- charge
These will cancel out making it plain MnSO4
If it was manganese (iii) sulfide the answer would be Mn2(SO4)3
Hello!
* First Step: to know Avogrado's Law
We know that by the Law of Avogrado, for each mole of substance we have 6.02*10²³ atoms, if:
** Second Step: to know the molar mass of the solute
The molar mass of of magnesium = 24.30 g/mol
*** Third step: make the ratio mass / mol with atoms
1 mol we have 6.02*10²³ atoms
1 mole of Mg we have 24.30 g
Then we have:
24.30 g ------------- 6.02*10²³ atoms
x ----------------------- 6.98*10^24 atoms
multiply cross
I Hope this helps, greetings ... DexteR! =)
