Answer: There are many forms of table salt: coarse salt, refined salt, iodized salt. It is a crystalline solid, white to very pale pink or gray in color, obtained from seawater or salt deposits. Salt obtained from seawater has crystals that are smaller or larger than rock salt. In nature, table salt consists mainly of sodium chloride (NaCl), but also a few other minerals (trace minerals). Table salt obtained from rock salt may appear more gray because of traces of trace minerals. Table salt is necessary for the survival of all living organisms, including humans. Table salt is involved in regulating the body's water content (liquid balance).

Write equations to show whether the solubility of either of the following is affected by pH: (b) Hg₂(CN)₂.
nata0808 [166]

<u> Increasing pH will increase the solubility of the Hg2(CN)2 by shifting </u><u>equilibrium </u><u>to right side.</u>

What is the meaning of OH in chemistry?

The chemical group, ion, or radical OH that consists of one atom of hydrogen and one of oxygen and is neutral or negatively charged.

Hg2(CN)2 + 2OH-  ----> 2HgO(s) + 2HCN

adding OH- to the mercury(l) cyanide  will cause the formation of the solid HgO.

therefore increasing pH will increase the solubility of the Hg2(CN)2 by shifting equilibrium to right side.

If I want to accelerate a mass of 3 kg at 5 m/s2 then how much force should I apply?
Stolb23 [73]

<u>Answer:</u> The force that must be applied is 15 N.

<u>Explanation:</u>

Force exerted on the object is defined as the product of mass of the object and the acceleration of the object.

Mathematically,

F=m\times a

where,

F = force exerted = ?

m = mass of the object = 3 kg

a = acceleration of the object = 5m/s^2

Putting values in above equation, we get:

F=3kg\times 5m/s^2=15N

Hence, the force that must be applied is 15 N.
