The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

Explanation:

Solubility is affected by temperature due to heatness.

Answer:

Explanation:

The protein comprises of two 60-kD polypeptides and two 40-kD polypeptides. Each one of the 40-kD chains has a disulfide-bond which is directly bonded to a 60-kD chain.

The 100-kD units attach noncovalently to produce a protein with a molecular mass of 200 kD. The interaction among the different subunits in the protein is not affected by the Gel filtration chromatography.

Hence, the protein seems to be 200 kD in size. When SDS-PAGE takes place samples are being subjected to heat and therefore undergoing denaturation conditions. The aftermath effect of this causes disorganization in the 100 kD units.

However, the reducing agent (BME) main task is the reduction of disulfide bonds in a protein.

It implies that BME is responsible for the reduction between the R1-S-S-R2 bond between 40 kD and 60 kD to R1-SH and R2-SH, resulting in seperate proteins.

Answer:

2.408 moles of hydrogen are in the sample.

Explanation:

Molecular formula of acetic acid =CH3COOH

Ratio of carbon to hydrogen :2/4:1/2

Measured  number of moles of carbon atoms = 1.204

Let the moles of hydrogen be = x

Number of carbon atoms in 1.204 mol = 1.204mol*Avogadro number

Number of hydrogen atoms in x mol = x*Avogadro number

As we know that ratio of carbon to hydrogen atoms is 1:2.

1/2=1.204mol* avogadro/ x* avogadro

x = 2.408 moles

2.408 moles of hydrogen are in the sample.

1. The specific heat capacity of the sample of gold obtained is 0.81 J/gºC

2. The substance is not pure gold

The specific heat capacity of the sample of gold can be obtained as follow:

Heat loss = Heat gain

M₉C₉(M₉ –Tₑ) = MᵥᵥC(Tₑ – Tᵥᵥ)

2.74 × C₉(72.1 – 26.3) = 15.2 × 4.184 (26.3 – 24.7)

C₉ × 125.492 = 101.75488

Divide both side by 125.492

C₉ = 101.75488 / 125.492

C₉ = 0.81 J/gºC

From the above we can conclude that the substance is not pure gold since the calculated and standard value of the specific heat capacity of the gold sample is not the same

Explanation:

To answer this question, the general gas law equation is used. The General gas law is:

Pv = nRT

Where; P = standard atmospheric pressure (1 atm)

V = volume (L)

n = number of moles

R = Gas law constant

T = Temperature

For this question; volume = 1.00L, atmospheric pressure (P) = 1 atm, R = 0.0821 L-atm / mol K, T = 600K, n = ?

Therefore; Pv = nRT

n = PV/RT

n = 1 × 1/ 0.0821 × 600

n = 1/49.26

n = 0.0203moles

Hence, there are 0.02 moles of gas.

The number of mole of the gas present in the cylinder is 0.02 mole

From the question given above, the following data were:

Temperature (T) = 600 K

Volume (V) = 1 L

Pressure (P) = 1 atm

The number of mole of the gas present in the cylinder can be obtained by using the ideal gas equation (PV = nRT) as illustrated below:

Temperature (T) = 600 K

Volume (V) = 1 L

Pressure (P) = 1 atm

Gas constant (R) = 0.0821 atm.L/Kmol

1 × 1 = n × 0.0821 × 600

1 = n × 49.26

Divide both side by 49.26

[tex]n = \frac{1}{49.26}\\\\[/tex]

Thus, 0.02 mole of the gas is present in the cylinder.

Hey there!

From question;

The molecular mass of NH₄OH is 35.

Avogadro number = 6.023*10²³ molecules.

Then,

From mole concept,

Molecular mass =  Avogadro number

So, 35 grams contains  6.023*10²³ molecules.

1 gram contains [tex]\frac{ 6.023*10^{23} }{35}[/tex] molecules.

52.1 grams contains [tex]\frac{6.023*10^{23} }{35} *52.1[/tex] molecules.

Therefore, 52.1 grams contains 8.96*10²³ molecules.

The number of moles of Co that would be required to react with 6.14 moles of P4 would be 36.84 moles

From the equation of the reaction:

6Co + P4 → 2Co3P2

For every 1 mole of P4, 6 moles of Co is required for complete reaction.

Thus, the mole of Co that would be needed for 6.14 moles of P4 would be:

                      6 x 6.14 = 36.84 moles

Answer:is 15.2%

Explanation:

Got it wrong and this the correct answer it told me

The percentage of water in the original sample is 15.2 %.

From the information provided in the question;

Weight of the wet sample = 5.00g

Weight of the dried sample = 4.24g

Loss in mass =  5.00g - 4.24g = 0.76 g

percentage of water in the original sample = Difference in mass between wet and dry sample/ mass of wet sample × 100/1

Hence, when we substitute values;

percentage of water in the original sample =  0.76 g/5.00g × 100/1

percentage of water in the original sample = 15.2 %

So, the percentage of water in the original sample is 15.2 %.

i learned this last week

Answer:

Explanation:

In this problem, we have 50.0 g of solute and 150.0 g of water. The total mass of the solution will thus be 50.0 g + 150.0 g = 200.0 g. The mass percent will be 50.0g/200.0 g (x100%) = 25.0 %.

Mass percent of a solution can be defined as grams of solute per 100 grams of solution.  In this problem, we have 50.0 g of solute and 150.0 g of water.  The total mass of the solution will thus be 50.0 g + 150.0 g = 200.0 g.  The mass percent will be 50.0g/200.0 g (x100%) = 25.0 %.  You can also look at it another way.  Since you have 50 g solute in 200 g solution, you will have 25 g solute in 100 g solution.  By the definition provided above, this is a 25% by mass solution.

Answer: As air is heated its density decreases because its mass remains constant but its volume increases. As air is cooled, its density increases because its mass remains constant but its volume decreases. ... The decrease in density as air is heated causes it to rise above cooler, more dense air.
