This question is answered with respect to following attached graph.

Answer:
            T<span>he solubility of <u>NaCl</u> is least affected by temperature.

Explanation:
                    When any solute is dissolved in water it either releases heat (Exothermic Reaction) or absorbs heat (Endothermic Reaction). This heat absorbed or released is called as Heat of Solution.
                     Heat of solution depends upon heat of ionization (endothermic process) and heat of hydration (exothermic process). When heat of ionization is greater than heat of hydration then the reaction will be endothermic and vice versa.
                     In case of NaCl the heat of Ionization and Heat of Hydrations are almost same. That is why the solubility of NaCl is least effected by temperature.</span>

laila [671]

Answer:

The timber companies removing all the trees from entire hillside when they are harvesting logs is a practice that could cause the following when it is time to plant in spring:

1. It could affect the quality of plant needed nutrients in the soil and beneficial microorganism population in the soil which could impact negatively the planting season.

2. Trees serves as protection of soil nutrients against wind erosions, so the soil nutrients would be affected.

The farmers tilling the soil means preparing the soil for a farming season as the following effect:

1. Helps control weed for the planting season.

2. This practice could further encourage soil erosion if not done well.

3. Tilling the soil could make leftover plants from the felling of trees mix well with the soil and also add nutrients to the soil when they decay.

The viscosities of several liquids are being compared. All the liquids are poured down a slope with equal path lengths. The liqu
boyakko [2]

Explanation:

The property of a substance to resist the flow of motion is known as viscosity. And, more is the density of a substance more will be its viscosity.  

Whereas, lesser is the density of a substance then it is easy for the substance to move.

This means that more is the viscosity of a substance least will be its flow and when a substance has lesser viscosity then it will readily flow from one point to another.

Thus, we can conclude that the viscosities of several liquids are being compared. All the liquids are poured down a slope with equal path lengths. The liquid with the highest viscosity will reach the bottom last.

Calculate the wavelength of yellow light produced by a sodium lamp if the frequency of radiation is 3.34 x 10^14 Hz
max2010maxim [7]

Answer :  The wavelength of yellow light produced by a sodium lamp is, 8.98\times 10^{-7}m

Explanation : Given,

Frequency of radiation = 3.34\times 10^{14}Hz=3.34\times 10^{14}s^{-1}

conversion used : Hz=s^{-1}

Formula used :

\nu=\frac{c}{\lambda}

where,

\nu = frequency of radiation

\lambda = wavelength of radiation

c = speed of light = 3\times 10^8m/s

Now put all the given values in the above formula, we get:

3.34\times 10^{14}s^{-1}=\frac{3\times 10^8m/s}{\lambda}

\lambda=8.98\times 10^{-7}m

Therefore, the wavelength of yellow light produced by a sodium lamp is, 8.98\times 10^{-7}m
