Answer: Water is polar and salts form ions in solution.

Explanation:

According to the concept of “Like dissolves like”, the polar solutes dissolve in polar solvents, and non-polar solutes dissolve in non-polar solvents.

Water being a polar solvent due to large electronegativity difference between hydrogen and oxygen is able to interact with the ions of the solute.

As water molecules are also polar in nature. So, oppositely charged ions interact with each other and dissolve in it.

Water can form hydrogen bonds with most of the substances and hence dissolve them . Thus water is considered as a universal solvent.

Calculate the approximate amount os sodium hydroxide needed to make 500ml if a. 3 naoh solution.
Rainbow [258]

6 gram of sodium hydroxide (NaOH) needed to make 500ml if  0.3  NaOH solution.

<h3>What is molarity? </h3>

Molarity (M) is the amount of a substance in a certain volume of solution.

Molarity is defined as the moles of a solute per liters of a solution.

The unit of molarity is mol/L.

Volume of NaOH = 500 mL

Molarity of the aqueous solution = 0.3 M

Molar mass of NaOH= (23+16+1) g = 40g

Let the mass of NaOH be X.

Now , according to formula number of moles of a given substance = given mass / molar mass

Therefore, no. of moles of NaOH =  X/40

Since, molarity = number of moles of solute/ volume of solution in liter.

Hence,  0.3 = ( X /40) / (500 / 1000)

Solving this we get X= 6g

6 gram of sodium hydroxide (NaOH) needed to make 500ml if  0.3  NaOH solution.

Rank the compounds NH3, CH4, and PH3 in order of decreasing boiling point. Choices: A) NH3 &gt; CH4 &gt; PH3 B) CH4 &gt; NH3 &gt
Andre45 [30]

Answer:

C) NH3 > PH3 > CH4

Explanation:

The boiling point of a substance depends on the nature of intermolecular interaction between the molecules of the substance. The greater the magnitude of intermolecular interaction between the molecules of the substance, the higher the boiling point of the substance.

Both NH3 and PH3 have intermolecular hydrogen bonding between their molecules. However, since nitrogen is more electronegative than phosphorus, the magnitude of intermolecular hydrogen bonding in NH3 is greater than in PH3 hence NH3 has a higher boiling point than PH3.

CH4 molecules only have weak dispersion forces between them hence they exhibit the lowest boiling point.
