A colligative property of a solution is one that depends 1. on the identity of the solute and the concentration of the solution.
Tanzania [10]

Answer:

The correct answer is option 2.

Explanation:

Colligative property is defined as property which depends upon only on the numbers of particles of solute dissolved in definite amount of  solvent, It do not depend on the nature of the solute.

For example : NaCl solution with 0.4 molal will show same colligative properties as a that of the glucose solution with 0.04 molal concentration.

The following are the examples of colligative property:

1. Relative lowering of vapor pressure.

2. Osmotic pressure

3. Elevation in boiling points

4. Depression in freezing point

Why would you need a locating agent in an experiment to separate amino acids by chromatography
Nadusha1986 [10]

A locating agent is needed in an experiment to separate amino acids by chromatography as it helps to analyze colorless substances on paper.

<h3>What is chromatography?</h3>

Chromatography is an analytical method frequently used to separate a chemical mixture into its components, allowing for in-depth analysis of each component.

There are many different types of chromatography including liquid, gas, ion-exchange, and affinity chromatography, but they all use the same basic principle.

<h3>What is the use of a locating agent in Chromatography?</h3>

In paper chromatography, colorless compounds are examined using a locating agent.

It is a chemical that combines with colorless substances to produce colorful compounds that are easy to see for analysis. Ninhydrin spray is an example of a locating agent of this type.

Thus, a locating agent is used in an experiment to separate amino acids by chromatography as it helps in determining colorless substances on paper.

1 point If the boy is pushing with 50N of force and the static friction resistance is 70N of force, what will happen? *​
solniwko [45]
Nothing, he shouldn’t be able to move it. Think about it like this say you try really hard to push something that is 5,000 pounds and you push as hard as you can. Well you can’t move it bc it weighs more than you can push. I’m sure their is a equation you can use to see how much you can push (body weight=force?)

How many atoms are in 58.93 grams of cobalt (Co)?
Vadim26 [7]
If you have 58.93g of Co it means that you only have 1 mol (use a periodic table to find the answer, if you had more find it by proportion, it's easier). 
There's 6.022 x 10^23 atoms per mol so you have 6.022 x 10^23 atoms of Co.
(once again if you had more mol, you could find the answer by proportions).
