Explanation:
Answer: (a) The solubility of CuCl in pure water is .
(b) The solubility of CuCl in 0.1 M NaCl is .
Explanation:
(a) Chemical equation for the given reaction in pure water is as follows.
Initial: 0 0
Change: +x +x
Equilibm: x x
And, equilibrium expression is as follows.
x =
Hence, the solubility of CuCl in pure water is .
(b) When NaCl is 0.1 M,
,
,
Net equation:
= 0.1044
So for,
Initial: 0.1 0
Change: -x +x
Equilibm: 0.1 - x x
Now, the equilibrium expression is as follows.
K' =
0.1044 =
x =
Therefore, the solubility of CuCl in 0.1 M NaCl is .
Explanation:
- Electrons are negatively charged particles that orbits the nucleus.
- Chemical and physical properties of elements are usually determined by the number of electrons they posses.
- Electrons are the basis of the chemical changes in which atoms undergo.
- Chemical properties of atoms are a function of the number of electrons they posses.
- When atoms combine, they do so in order to attain stability.
- Combination of atoms involves the loss or gain or sharing of electrons between atoms.
- When atoms combine with one another, they form chemical bonds.
- These chemical bonds can be between two atoms or between molecules.
- The nature of the chemical bonds determines the physical and chemical properties of a host of compounds.
- For example, metallic bonds in metals is responsible for their conductivity and malleability.
- It is also responsible for the wide range of reactions they undergo.

True, because matter is anything that occupies space and has mass.
Answer:
Sucrose contains two sugars (fructose and glucose) joined by their glycosidic bond in such a way as to prevent the glucose isomerizing to aldehyde, or the fructose to α-hydroxy-ketone form. Sucrose is thus a non-reducing sugar, which does not react with Benedict's reagent.
