Answer:

The correct answer is due to solubility.

Explanation:

The solubility of a substance called solvent in another called solute is determined by the balance of intermolecular forces between the solvent and solute. This is expressed by the variation in entropy that accompanies solvation. Factors that can vary such as temperature and pressure influence this equilibrium, thus changing the solubility of the substances.

Explanation:

The attraction between solute particles affect its ability to dissolve in the solution because more is the attraction between particles less will be the chances that solute particles will combine to the solvent particles.

As a result, there will be decrease in solubility with increase in force of attraction between solute particles.

Whereas when there is less force of attraction between solute particles then more easily solute particles will combine with the solvent particles.

Hence, with decrease in force of attraction between solute particles, the rate of dissolution will increase.

The molar mass of barium nitrate (ba(no3)2) is 261.35 g/mol. what is the mass of 5.30 × 1022 formula units of ba(no3)2? 0.0900 g

liberstina [14]

Molar mass is the ratio of the mass to that amount of the substance. The mass of the barium nitrate in the formula unit is 23.0 grams.

The mass of a substance is the product of the molar mass of the compound and the number of moles of the compound.

Given,

Molar mass of barium nitrate = 261.35 g/mol

If, $6.022 \times 10^{23}$ have a mass of 261.35 g/mol then, $5.30 \times 10^{22}$ formula units will have a mass of,

$\begin{aligned}& = \dfrac{261.35 \times 5.30 \times 10^{22}}{6.022\times 10^{23}}\\\\&= 23.0\;\rm gm\end{aligned}$

Therefore, option C. 23.0 gm is the mass of barium nitrate.

The chemical equation for a reaction between K2Cr2O7 and HCl is shown. K2Cr2O7 + 14HCl → 2CrCl3 + 2KCl + 3Cl2 + 7H2O

guapka [62]

<u>Answer: </u>The correct answer is Option b.

<u>Explanation:</u>

Oxidizing agent is defined as the chemical reagent which helps the other chemical compound to get oxidized and itself gets reduced. The oxidation state for these species gets reduced because they are undergoing reduction reaction.

For the given chemical equation:

$K_2Cr_2O_7+14HCl\rightarrow 2CrCl_3+2KCl+3Cl_2+7H_2O$

Oxidation state of Chromium is getting reduced from +6 to +3 and oxidation state of chlorine getting increased from -1 to 0.

Hence, $K_2Cr_2O_7$ acts like and oxidizing agent because it is itself getting reduced to $CrCl_3$

Therefore, the correct answer is Option b.
