Increasing the amount of water in which the sugar is dissolved will increase the frequency of collisions between the sucrose mol

Sonja [21]

Answer: The given statement is true.

Explanation:

When we increase the amount of solvent which is water in this case then it means there will occur an increase in the molecules. Hence, there will be more number of collisions to take place with increase in number of molecules.

Therefore, more is the amount of interaction taking place between the molecules of a solution more will be its rate of hydrolysis.

Thus, we can conclude that the statement increasing the amount of water in which the sugar is dissolved will increase the frequency of collisions between the sucrose molecules and the water molecules resulting in an increase in the rate of hydrolysis, is true.

Analysis of a compound of sulfur, oxygen and fluorine showed that it is 31.42% S and 31.35% O, with F accounting for the remaind

Leya [2.2K]

Answer:

The molecular formula is SO2F2

Explanation:

Step 1: Data given

Suppose the mass of compound = 100 grams

The compound contains:

31.42 % S = 31.42 grams S

31.35 % O = 31.35 grams O

100 - 31.42 - 31.35 = 37.23 F

Molar mass of S = 32.065 g/mol

Molar mass F = 19.00 g/mol

Molar mass O = 16.00 g/mol

Step 2: Calculate moles

Moles = mass / molar mass

Moles S = 31.42 grams / 32.065 g/mol

Moles S = 0.9799 moles

Moles 0 = 31.35 grams / 16.00 g/mol

Moles 0 = 1.959 moles

Moles F = 37.23 grams / 19.00 g/mol

Moles F = 1.959 moles

Step 3: Calculate mol ratio

We divide by the smallest amount of moles

S: 0.9799 / 0.9799 = 1

F: 1.959/ 0.9799 = 2

O : 1.959 / 0.9799 = 2

The empirical formula is SO2F2

This formula has a molecular mass of 102.06 g/mol

This means the empirical formula is also the molecular formula : SO2F2

How many grams of fluorine are contained in 8 molecules of boron trifluoride?

Lelu [443]

<h3>Answer:</h3>

7.57 × 10⁻²² g of F

<h3>Solution:</h3>

Data Given:

Number of Molecules = 8

M.Mass of BF₃ = 67.82 g.mol⁻¹

Mass of Fluorine atoms = ?

Step 1: Calculate Moles of BF₃

Moles = Number of Molecules ÷ 6.022 × 10²³ Molecules.mol⁻¹

Putting value,

Moles = 8 Molecules ÷ 6.022 × 10²³ Molecules.mol⁻¹

Moles = 1.33 × 10⁻²³ mol

Step 2: Calculate Mass of BF₃:

Moles = Mass ÷ M.Mass

Solving for Mass,

Mass = Moles × M.Mass

Putting values,

Mass = 1.33 × 10⁻²³ mol × 67.82 g.mol⁻¹

Mass = 9.0 × 10⁻²² g

Step 3: Calculate Mass of Fluorine Atoms:

As,

67.82 g BF₃ contains = 57 g of F

So,

9.0 × 10⁻²² g will contain = X g of F

Solving for X,

X = (9.0 × 10⁻²² g × 57 g) ÷ 67.82 g

X = 7.57 × 10⁻²² g of F
