The saturation point for a solution is 50.0 grams of solute per 500. grams of solvent. If you pour 70.0 grams of
solute into 800. grams of solvent, how many more grams of solute can you dissolve before reaching saturation?

Answers

Answer:

10.0g of solute before reaching saturation

Explanation:

A saturated solution is the solution that contains the maximum amount of solute that can be dissolved. In the problem, you can have

50.0g of solute / 500.0g Solvent

Now, in 800.0g solvent you can dissolve:

800.0g Solvent * (50.0g solute / 500.0g Solvent) = 80.0g of solute can be added

As you dissolve initially 70.0g of solute. You can add:

80.0g - 70.0g =

10.0g of solute before reaching saturation

What is the rate of diffusion of NO gas to CO gas?

Answers

Answer:

0.97

Explanation:

Let R₁ represent the rate of diffusion of NO.

Let R₂ represent the rate of diffusion of CO.

Molar mass of NO (M₁) = 14 + 16 = 30 g/mol

Molar mass of CO (M₂) = 12 + 16 = 28 g/mol

Thus, the rate of NO to CO can be obtained as follow:

R₁ /R₂ = √(M₂/M₁)

R₁ /R₂ = √(28/30)

R₁ /R₂ = √(28/30)

R₁ /R₂ = 0.97

R₁ : R₂ = 0.97

NO : CO = 0.97

Therefore, the rate of diffusion of NO to CO is 0.97

Answer:

Explanation:

Electronegativity is defined as the ability of an atom in a bond to attract the shared electrons of the bond towards itself.

Electronegativity is a periodic trend that decreases down the group and increases across the period.

Hence, if i want to arrange Beryllium, Barium, Strontium, Magnesium, Calcium in order of increasing electronegativity, i will have;

Barium<Strontium<Calcium <Magnesium< Beryllium

How many moles of gas would you have if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature

Answers

Answer: There are 3.2 moles of gas if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature.

Explanation:

Given: Volume = 38.0 L

Pressure = 1430 mm Hg (1 mm Hg = 0.00131579 atm) = 1.9 atm

Temperature = 273.15 K

Using ideal gas equation, the moles of gas will be calculated as follows.

[tex]PV = nRT\\[/tex]

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T =temperature

Substitute the values into above formula as follows.

[tex]PV = nRT\\1.9 atm \times 38.0 L = n \times 0.0821 L atm/mol K \times 273.15 K\\n = \frac{1.9 atm \times 38.0 L}{0.0821 L atm/mol K \times 273.15 K}\\= 3.2 mol[/tex]

Thus, we can conclude that there are 3.2 moles of gas if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature.

Answer: The one direction where energy as heat will be initially transferred between the blocks is from block D to block A.

Explanation:

A substance like metal box that has high temperature will have more kinetic energy between its molecules due to which there will be more number of collisions between them.

Hence, it is able to transfer its heat energy more  readily ac compared to a substance with low heat energy.

As a result, in the given diagram as temperature is increasing from block A to block B so heat energy will be transferred from block D to block A.

Thus, we can conclude that one direction where energy as heat will be initially transferred between the blocks is from block D to block A.

You have 1.29 moles of hydrogen peroxide, H2O2. How many grams is this?

Answers

Answer:

m = 43.87 grams

Explanation:

Given that,

Number of moles, n = 1.29 moles

The molar mass of H₂O₂ is, M = 34.0147 g/mol

We know that,

[tex]n=\dfrac{m}{M}[/tex]

Where

m is mass of H₂O₂

So,

[tex]m=n\times M\\\\m=1.29\times 34.0147 \\\\m=43.87\ g[/tex]

So, there are 43.87 grams of H₂O₂.
