Acid and base  compounds break up into ions solution.

<h3><u> Explanation:</u></h3>

Acids are the compounds that breaks into hydrogen ions. Bases are those compounds that dissociate into hydroxide or OH - ions. When you put an ionic or electrovalent compound into water , then it breaks apart into two ions.If one of them is H+ ions, then the solution is known to be acidic.

A good  example of strong acid is hydrogen chloride which breaks into water and releases ions. If we take the example of bases than if one of the releasing ion is OH- in the solution than the solution is basic . A good example of this is sodium hydroxide (NaOH).

A rectangular block of solid carbon (graphite) floats at the interface of two immiscible liquids.
Sergio039 [100]

Explanation:

Let us take the volume of block is x.

Since, the block is floating this means that it is in equilibrium. Formula to calculate net force will be as follows.

                F_{net} = Buoyancy force(F_{b}) - weight force(w)

Also, buoyancy force (F_{b}) = (volume submerged in water × density of water) + (volume in oil × density of oil)

          (F_{b}) = (0.592 V \times \rho) + (1 - 0.592)V \times 1000 g          

                      = (0.592 V \times \rho + 408 V) g

As,   W = V × density of graphite × g

It is given that density of graphite is 2.16 g/cm^{3} or 2160 kg/m^{3}.

So, W = 2160 V g

F_{net} = (0.592 V \rho + 408 V) g - 2160 V g = 0

            0.592 \rho = 1752

     \rho = 2959.46 kg/m^{3} or 2.959 g/cm^{3} is the density of oil.

It is given that mass of flask is 124.8 g.

Mass of 35.3 cm^{3} oil = 35.3 \times 2.959 104.7 g

Hence, in second weighing total mass will be calculated as follows.

                       (124.8 + 104.7) g

                       = 229.27 g

Thus, we can conclude that in the second weighing mass is 229.27 g.

Identify the true statements about colloids.
Mashutka [201]

Answer : The true statements are:

(a) Emulsions are a type of colloid

(b) The particles of a colloid are larger than the particles of a solution

(d) Many colloids scatter light (tyndal effect)

Explanation :

Colloid : It is defined as the solution in which the one substance is insoluble in another solution that means the insoluble substance rotating in the solution.

The particles of a colloid are larger than the particles of a solution.

Colloid do not separate on standing.

Cannot be separated by filtration.

Scatter light (Tyndall effect).

For example :

Milk is considered as a colloid because various substances (fats, proteins etc..) are present in milk which are suspended in a solution.

Suspension : It is a heterogeneous mixture in which some of the particles are settle down in the mixture on standing or over time.

The particles in a suspension are far larger than those of a solution.

Emulsion : It is a mixture of two or more liquids that are normally immiscible.

Emulsions are a type of colloid.
