Agitate (stir) the solution
Heat the solution
Shake the solution
Explanation:
To increase the solubility rate, we can:
- Agitate the solution by stirring it. This will bring more of the solute in contact with the solvent. The process of stirring enables contact between solute faces and the dissolving medium.
- Heating the solution also helps. Increase in temperature by heating a solution generally cause a rise in reaction rate. This allows for more frequent collisions between the particles of the specie.
- Shaking the solution brings solute and solvent into more contact.

Answer:
-the reactants have more energy stored because you didn't get a great amount ( if any ) of energy released after the reaction was complete.
-Mg + O2 = MgO + energy
Answer:
2Mg(s) + O2(g) ----->2MgO(s)
Explanation:
In writing a balanced chemical reaction equation, the rule of thumb is that the number of atoms of each element on the reactant side must be the same as the number of atoms of the same elements on the products side.
Hence for the reaction of magnesium and oxygen shown below;
2Mg(s) + O2(g) ----->2MgO(s)
We notice that there are two atoms each of magnesium and oxygen on both sides of the reaction equation hence the equation is balanced.
