52.31g of Cu(NO3) is dissolved in enough water to make 1.400 mL of total solution. what is the molarity of solute in the resulting soultion?

Answers

Answer 1

Molarity :

The number of moles of solute per liter of solution is known as molarity or molar concentration. It is used to express the concentration of a given solute in a solution.

It can be calculated using the formula, Molarity = [tex]\frac{number-of- moles-of-solute}{Volume-of-the-solution-in-liters}[/tex]

Given data:

Mass of the solute ( Cu(NO3) ) = 52.31 g

Volume of the solution = 1400 mL = 1.4 Liters,

Then, Molar mass of the solute = 125.55 g/mol

Then, number of moles of solute = [tex]\frac{mass of solute}{molar mass of solute}[/tex]

                                                        = [tex]\frac{52.31}{125.55}[/tex] = 0.417 mole

Then, Molarity = [tex]\frac{0.417}{1.4}[/tex] = 0.298 M

Therefore, the molarity of solute in the resulting solution is = 0.298 M

if the rate of reaction increases by a factor of 9.6 when the concentration of reactant increases by a factor of 3.1, what is the order of the reaction with respect to this reactant?

Answers

If the rate of reaction increases by a factor of 9.6 when the concentration of reactant increases by a factor of 3.1 then order of the reaction with respect to this reactant is  1/3

Rate of reaction is the speed at which a chemical reaction proceeds

Here given data is

Rate of reaction = 9.6

Concentration of reactant  = 3.1

We have to calculate order of the reaction = ?

So we can write

R = K[C]ⁿ

Where R is the reaction rate and K is a constant

Here C is the concentration of the reactant

rate of reaction increases by a factor of 9.6 when the concentration of reactant increases by a factor of 3.1 then

9.6 = K× [3.1]ⁿ

Dividing this equation we get

1/9.6 = 1/3.1ⁿ

3n = 1

n = 1/3

Then the order of the reaction with respect to this reactant is 1/3

a gas reacts with a solid that is present in large chunks, then the reaction is run again with the solid pulverized. how does the increase in the surface area of the solid affect the rate of its reactoi

Answers

An increase in the surface area of the solid will increase the rate of the reaction.

The reaction rate will be influenced by the solid's surface area if one of the reactants is solid. This is due to the fact that the two kinds of molecules can only collide at the liquid-solid interface, also known as on the surface of the solid. The reaction rate will rise due to a more significant interaction of the surface areas between the two molecules when the solid is pulverized into a gas. If a reactant has a larger surface area: The other reactant is exposed to more particles. Particles are more likely to collide, which results in more successful collisions per second this will influence the reaction speed to increase.

The shortest covalent bond is the H-F bond. Therefore, option (A) is correct.

What is the bond length order of hydrogen halides?

The electronegativity decreases down the group and the Fluorine is the most electronegative atom in the periodic table. The size of the atoms also increases as we go down the group.

The bond length of the hydrogen halides will follow the order HF < HCl < HBr < HI. The radius of the Iodine atom is the largest and to form a molecule, the hydrogen atom will be farthest as compared to all hydrogen halides.

The molecule with Fluorine will have the shortest bond length because its atom has the smallest size, making them attach very closely. So the covalent bond of hydrogen fluoride will be the shortest.

The relationship between bond length and bond strength is inverse in nature. The bond length of HI is the greatest, it will have the least bond strength. So the order for bond strength of the hydrogen halides is  HF > HCl > HBr > HI.

Answers

Answer:

384.9 mL.

Explanation:

What is given?

Volume 1 (V1) = 823.7 mL.

Pressure 1 (P1) = 351.8 torr.

Pressure 2 (P2) = 752.9 torr.

What do we need? Volume 2 (V2).

Step-by-step solution:

This is a Boyle's Law problem. Boyle's law states that the volume of a given mass of gas varies inversely with the pressure when the temperature is kept constant. An inverse relationship is described in this way. As one variable increases in value, the other variable decreases.

The formula of the law is:

[tex]P_1V_1=P_2V_2.[/tex]

Where P is pressure and V is volume. We want to find volume 2, 'V2'. So let's solve for 'V2' and replace the given data that we have in the new formula:

[tex]V_2=\frac{P_1V_1}{P_2}=\frac{351.8\text{ torr}\cdot823.7\text{ mL}}{752.9\text{ torr}}=384.882\text{ mL}\approx384.9\text{ mL.}[/tex]

The new volumewill be 3384.9 mL You can note as the pressure is increasing, the volume is decreasing.

How many grams of Cu are obtained by passing a current of 12 A through a solution of CuSO4 for 30 minutes?​

Answers

The quantity of Cu deposited at the cathode will be 7.117 grams.

Given,

Current (in Amperes) = 12 A

This will be equal to 12 C/s (in coulombs per second).

Therefore the total charge in 30 minutes will be:

Q = 12C/s × 30 min × 60 seconds/minute

=> Q = 21600 C

Now, the number of moles of copper which are plated out (n) will be :

n = Q / z·F

In the half-cell reaction,

the number of electrons ( for Cu ) will be = 2 (Cu 2+)

F, the Faraday's constant = 96,485 per mole

We have already discussed that,

n = Q / z.F

=> n = 21600 / (2×96485)

=> n = 0.112 mol

So, 0.112 mol of Cu will be equal to:

Answers

The molarity of the Vitamin B1 Hydrochloride solution is 0.71M.

We know,

Molarity of a solution is defined as the ratio of the moles of the solute with respect to the volume of the solution in liters.

We know,

Moles = mass of solute dissolved/Molar mass of solute

Given mass of solute is dissolved is 53 grams.

Molar mass of Vitamin B1 Hydrochloride is 337 grams/mol

Moles of Vitamin B1 hydrochloride = 53/337

The volume of the solution is 220 ml.

We know,

1 ml = 1/1000 litres

220 ml = 220/1000 litres

So, putting all the values in the formula of molarity,

Molarity of solution = (53/337)/(220/1000)

Molarity of solution = 0.71

Answers

The ddt in the soil with half-life of 12 years needs 44.4 years to decompose.

We need to know about the half-life of the radioactive elements to solve this problem. The radioactive element will decay over time and follow the equation

N = No(1/2)^(t/t'')

where N is the final quantity, No is the initial quantity, λ is the decaying constant, t is time and t'' is the half-life of a radioactive element.

From the question above, we know that

N = 15 ppbm

No = 195

By substituting the given parameter, we can calculate the required for decomposing

N = No(1/2)^(t/t'')
