Answer:
The supersaturated solution
it is a solution usually very sugary
excess solute
the supersaturated solution is a solution
where there is solute and solvent, there is always interaction
Explanation:
The supersaturated solutions are solutions where the solute is in excess, the solute is in constant interaction with the solvent and being in excess it precipitates to the bottom of the solution.
A supersaturated solution has a very high osmolarity.

Explanation:
Free radicals unstable atoms because it can cause damage cells, as well as causing illness and aging, which means that it can cause harm into our bodies because it damages the DNA and the lipids which is also known as fatty acids
Answer: The activation energy of a particular reaction determines the rate at which it will proceed. The higher the activation energy, the slower the chemical reaction will be. The example of iron rusting illustrates an inherently slow reaction.

Answer:
1.2 × 10^22 atoms.
Explanation:
Firstly, cations refers to the positively charged atom in the ionic compound, which is Na+.
Given the mass of NaCl as 1.17g, the number of moles of NaCl can be calculated this:
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Mole = mass/molar mass
Mole = 1.17/58.5
Mole = 0.02moles
Using Avagadro's number, 6.022 × 10^23 atoms of Na+ are in 1 mole of NaCl.
In 0.02 moles of NaCl, there are 0.02 × 6.022 × 10^23 of Na+
0.1204 × 10^23 atoms
1.2 × 10^22 atoms of Na+ (cation)
Answer:
2 Al(s) + 3 H₂SO₄(aq) ⇒ Al₂(SO₄)₃(aq) + 3 H₂(g)
Explanation:
Let's consider the unbalanced equation for the single replacement reaction between Al and Hâ‚‚SOâ‚„.
Al(s) + H₂SO₄(aq) ⇒ Al₂(SO₄)₃(aq) + H₂(g)
We will begin balancing S atoms by multiplying Hâ‚‚SOâ‚„ by 3.
Al(s) + 3 H₂SO₄(aq) ⇒ Al₂(SO₄)₃(aq) + H₂(g)
Then, we balance Al atoms by multiplying Al by 2.
2 Al(s) + 3 H₂SO₄(aq) ⇒ Al₂(SO₄)₃(aq) + H₂(g)
Finally, we get the balanced equation by multiplying Hâ‚‚ by 3.
2 Al(s) + 3 H₂SO₄(aq) ⇒ Al₂(SO₄)₃(aq) + 3 H₂(g)
