Answer: The density and electrical conductivity of the solutions can be measured

Explanation:

We could get three beakers and measure the mass of the solution by subtracting the mass of the beaker from mass of solution + beaker. After that, we use a measuring cylinder to determine the volumes of the three solutions. The density is then obtained from:

Density= mass/volume

The density of pure water is always 1gcm-3.

Measurement of electrical conductivity will distinguish between the salt and sugar solutions. The salt solution will have high electrical conductivity. The solution with the highest electrical conductivity is the salt solution while the solution with the least electrical conductivity is the sugar solution. Sugar does not conduct electricity in solution because it does not contain ions.

Answer:

Explanation:

A1. Chemical indicator, any substance that gives a visible sign, usually by a colour change, of the presence or absence of a threshold concentration of a chemical species, such as an acid or an alkali in a solution. An example is the substance called methyl yellow, which imparts a yellow colour to an alkaline solution.

A2. The reaction of an acid with a base is called a neutralization reaction. The products of this reaction are a salt and water. ... For example, the reaction of hydrochloric acid, HCl, with sodium hydroxide, NaOH, solutions produces a solution of sodium chloride, NaCl, and some additional water molecules

A3. Methyl orange has the property to color alkaline and neutral water yellow. If the water becomes acidic, it turns red immediately.

andrezito [222]

Answer:

The vegetative parts includes the roots, stems,leaves and the reproductive parts include flowers. ... The vegetative parts can reproduce new plants by the process of vegetative propagation but the reproductive parts cannot produce new plants directly instead they produce precursor of new plants that are seeds or fruits.
