Answer : When magnesium salts combine with the alkaline water it induces precipitation of solid Mg(OH)_2.

Explanation :

  • Chemical change : The chemical change occurs when a substance combine with the another substance to form a new substance.

         It can not be easily reversible.

        The new product is formed or precipitate may be formed.

  • Physical change : The physical change occurs when a substance combine with the another substance then no new compound is formed.

        It can be reversible.

       No new product is formed only changes occurs in the state or                 phase.

As per question, when magnesium salts combine with the alkaline water it induces precipitation of solid Mg(OH)_2.

The balanced chemical reaction is,

Mg^{2+}(aq)+2OH^-(aq)\rightarrow Mg(OH)_2(s)

That mean a new compound is formed by this reaction. So, the chemical change occurred in this reaction.

The sulfur atom of sulfur dioxide is considered to be sp2-hybridized. The expected bond angle is 120°, but is actually slightly
Alja [10]

Answer: The bonds are intermediate between double and single bonds

Explanation:

A closer look at the diagram below shows that the bonds in sulphur IV oxide are intermediate between double and single bonds. Hence they do not have the exact bond angle of single bonds. This is why the bond angle is not exactly 120°. There are two resonance structures in the diagram that clearly show this point.

A student made an initial 1:5 dilution of protein lysate. Then 2mL of that was added to 8mL of water. Lastly, the student made a
Licemer1 [7]

Answer:

The final dilution is 1:400

Explanation:

Let's analyze what we are told: we have an initial 1:5 dilution of protein lysate. This means that the initial solution (stock solution) was diluted 5 times. Then, from this dilution the student prepared another dilution taking 2 mL of the first dilution in 8 mL of water. This is the same as saying we took 1 mL of first dilution in 4 mL of water (the ratio is the same), so we now have a second 1:4 dilution of the first dilution (1:5). Finally, the student made a third 1:20 dilution, this means that the second dilution was further diluted 20 times.

So, to calculate the final dilution of protein lysate, we have to multiply all the dilution factors of every dilution prepared: in this case we have a final dilution of 1:20, this means we have a factor dilution of 20. But it was previously diluted 4 times, so we have a factor dilution of 20×4 = 80. However, this dilution was also previously diluted 5 times, so the new dilution factor is 80 × 5 = 400

This means that the final dilution of the compound was diluted a total of 400 times compared to the initial concentration of stock solution.
