Colligative properties depend on the amount of solute dissolved in a solvent. These set of properties do not depend on the type of species present. These properties include freezing point depression, boiling point elevation, osmotic pressure and vapor pressure lowering.

Answer:

Colligative properties depend on the quantity of solute and solvent and the identity of the solvent.

Explanation:

Colligative properties are defined as a set of intensive physical properties that result from the interactions between solute and solvent that form a solution. In this group of properties, we can find the <em>freezing point depression, boiling point elevation, osmotic pressure, and vapor pressure lowering.</em>

The mentioned properties dependon the amount of solute and solvent (concentration) and the nature of the solvent. this fact can be pictured by the freezing point depression formula:

T_{f} _{solvent} -T_{f} _{solution}  = K_{f}   _{x}   m

where T_{f} _{solvent} is the freezing point of the pure solvent, T_{f} _{solution} is the freezing point of the solution, K_{f} is the freezing point depression constant  and m is the molality

In the equation, it can be seen that the change of temperature of the solution with respect to the pure solvent depends on the molality, which is the ratio of moles of solute and mass of solvent. Moreover, the change also depends on the freezing point depression constant that is a characteristic of the solvent.

A.Which facilities contribute the most to recycling and the least to recycling based on the pie chart graphic?
nirvana33 [79]

Answer:

a) To determine the facilities that contribute the most to recycling check the pie chart and select the facility with the largest portion while to determine the facilities that contribute the least to recycling check the pie chart and select the facility with the smallest portion

b) Energy is saved because the products which are recycled usually require less energy to turn them into usable materials

c) It saves energy through recycling. It helps sustains the environment. It decrease the emission of green house gases

Explanation:

The question is not complete

a) Pie chart is the graphical representation of information in which the information is represented in a circle. The circle is divided into segments and the portion with the largest segment has the highest percentage.

To determine the facilities that contribute the most to recycling check the pie chart and select the facility with the largest portion while to determine the facilities that contribute the least to recycling check the pie chart and select the facility with the smallest portion

b) Extraction and processing of raw resources to make end products requires a lot of energy.  With recycling energy is saved because the products which are recycled usually require less energy to turn them into usable materials

c) It saves energy through recycling. It helps sustains the environment. It decrease the emission of green house gases.

If you are administering an insulin dose of 90.0 mg from a bottle at a concentration of 10.0 mg/mL,
Fiesta28 [93]

Answer:

9 mL.

Explanation:

Dosage of insulin is 90 mg

The concentration of insulin is 10 mg/mL

We need to find how many milliliters of the solution do you need to give the patient. It can be calculated as follows :

x=\dfrac{90\ \text{mg}}{10\dfrac{\text{mg}}{\text{mL}}}\\\\x=\dfrac{9}{1}\ \text{mL}

So, 9 mL of the solution is to be given to the patient.

When would formation of a derivative be a necessary step in this experiment?
const2013 [10]
<span>The formation of a derivative being a necessary step in the experiment lies in the importance of the derived structure. Often the derived product confers to reaction pathways which uses less reactive starting materials and more easily proceeds to completion. This also allows us to take a small amount of sample. The derived product at times is a general compound allowing its easy analysis. Often we encounter a product but we find it difficult to analyse it in ways we want. Here lies the essence of forming a derivative which often are simpler compounds allowing easier analysis yet having similar functional groups and structural properties. Also sometimes we encounter problems when our desired product is unstable and forms stable degraded products. But if we somehow manage to synthesize a derivative it may be relatively stable and form no degradation products. It would be stable at least for a significant period of time making it easier to study its properties. The derived product also at times are synthesized using general reaction pathways facilitating a way of easier synthesis and helping it to correlate with other similar reaction pathways and products.So the above paragraph accounts for the need of derivatives. When we encounter problems similar to those mentioned above it becomes necessary for a researcher to form rather synthesize a derivative.</span>
