Question
Compose a poem related to saturated and unsaturared solution
Solution 1

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.

Question
Why are free radicals unstable atoms and how can they harm our bodies?
Solution 1

Answer:

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

Solution 2
Free radicals are atoms that contain an unpaired electron. Due to this lack of a stable number of outer shell electrons, they are in a constant search to bind with another electron to stabilize themselves—a process that can cause damage to DNA and other parts of human cells.
Question
How does activation energy influence a reaction
Solution 1

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.

Question
What number of cations is present in 1.17g of sodium chloride ?
Solution 1

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)

Question
What is the completed balanced reaction for the replacement Al×H2SO4
Solution 1

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 H₂SO₄.

Al(s) + H₂SO₄(aq) ⇒ Al₂(SO₄)₃(aq) + H₂(g)

We will begin balancing S atoms by multiplying H₂SO₄ 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 H₂ by 3.

2 Al(s) + 3 H₂SO₄(aq) ⇒ Al₂(SO₄)₃(aq) + 3 H₂(g)
