Rank the following aqueous solutions in order of increasing<br> (c) freezing point;

0.01 m $AgNO_{3}$ < 0.03 m $CuSO_{4}$ < 0.04 m urea

As molal concentration rises, so does freezing point depression. It can be expressed mathematically as ΔTf = Kfm.

<h3>What is Colligative Properties ?</h3>

The concentration of solute particles in a solution, not the composition of the solute, determines a colligative properties .

Osmotic pressure, boiling point elevation, freezing point depression, and vapor pressure reduction are examples of ligand-like properties.

<h3>What is freezing point depression?</h3>

When less of another non-volatile material is added, the temperature at which a substance freezes decreases, a process known as Freezing-point depression.

Examples include combining two solids together, such as contaminants in a finely powdered medicine, salt in water, alcohol in water.

An significant factor in workplace safety is freezing points.
If a substance is kept below its freezing point, it may become more or less dangerous.
The freezing point additionally offers a crucial safety standard for evaluating the impacts of worker exposure to cold conditions.

Which element can expand its valence shell to accommodate more than eight electrons? which element can expand its valence shell

Anvisha [2.4K]

<span>According to octet rule, atoms with an atomic number less than 20 tend to combine with other atom such that both of these atoms have eight electrons in their valence shells, which gives them the same electronic configuration as that of noble gas.

However, there are few compound that donot obey octel rule. Among the elements mentioned above i.e. oxygen and helium obeys octet rule.

In case of nitrogen, oxide of nitrogen (like NO and NO2) have incomplete octet.

While there are few compounds of Br wherein Br has expanded octet. For example, in BrF5, Br has 12 electrons in valence shell. </span>

A chemist requires 0.802 mol Na2CO3 for a reaction. How many grams does this correspond to?

Komok [63]

Answer:

Ok:

Explanation:

So grams = mols*MolarMass. Here, MolarMass (MM) = 105.99g which can be found using the periodic table. mols is given to be 0.802. We can then plug in to get that it corresponds to 85.0g.
