Why does sugar water have a higher boiling point then salt water

Sugar molecules dont split further. so if you add a 1:1 ratio of sugar and water, it will have less particles than salt and water causing it to have a higher boiling point

The colligative properties of solutions depend upon the number of molecules dissolved in the solution, but not on the type of solutes. Pure water freezes at 32 F and boils at 212 F. However, adding any kind of solute to pure water will lower the freezing point.

Find the volume of 0.130M sulfuric acid necessary to react completely with 65.9g sodium hydroxide

xxTIMURxx [149]

The volume of the 0.130 M sulfuric acid, H₂SO₄ required to react completely with 65.9 g sodium hydroxide, NaOH is 6.34 L

We'll begin by calculating the number of mole of in 65.9 g sodium hydroxide, NaOH. This can be obtained as follow:

Mass of NaOH = 65.9 g

Molar mass of NaOH = 23 + 16 + 1 = 40 g/mol

Mole = mass / molar mass

Mole of NaOH = 65.9 / 40

Next, we shall determine the number of mole of H₂SO₄ needed to react with 1.6475 mole of NaOH. This can be obtained as follow:

2NaOH + H₂SO₄ —> Na₂SO₄ + 2H₂O

From the balanced equation above,

2 moles of NaOH reacted with 1 mole of H₂SO₄.

Therefore,

1.6475 mole of NaOH will react with = $\frac{1.6475}{2} \\\\$ = 0.82375 mole of H₂SO₄.

Finally, we shall determine the volume of 0.130 M sulfuric acid, H₂SO₄ required for the reaction.

Molarity of H₂SO₄ = 0.130 M

Mole of H₂SO₄ = 0.82375 mole

<h3>Volume of H₂SO₄ =? </h3>

Volume = mole / Molarity

Volume of H₂SO₄ = 0.82375 / 0.130

<h3>Volume of H₂SO₄ = 6.34 L </h3>

Therefore, the volume of the 0.130 M sulfuric acid, H₂SO₄ required for the reaction is 6.34 L

Without doing any calculations, determine which sample contains the most atoms.

lana66690 [7]

Answer:

Explanation:

1g of Boron has the most number of atoms. This is simply because it has the highest number of moles.

Since 1 mole contain 6.22 × 10^23 atoms, the atom that has most moles closer to 1 will contain most atoms.

This in fact can be calculated from the fact that the number of moles equal mass divided by the atomic mass.

The mass here is equal I.e 1g and thus the dividing factor will be the atomic mass. The atom with the highest atomic mass here us thorium and thus will give the lowest number of moles. Zinc follows suit in that order with Boron at the top of the other and thus will contain the highest number of atoms.

Which is a Characteristic of a non elecrolyte

myrzilka [38]

Answer:

A nonelectrolyte is a substance that does not exist in an ionic form in aqueous solution. Nonelectrolytes tend to be poor electrical conductors and don't readily dissociate into ions when melted or dissolved. Solutions of nonelectrolytes do not conduct electricity.
