Describe how temperature changes the average Molecular kinetic energy?

Answers

Answer 1
an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often.
Answer 2

According to Kinetic Molecular Theory, an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often. If the reaction is kept at constant pressure, they must stay farther apart, and an increase in volume will compensate for the increase in particle collision with the surface of the container.

How many grams is 2.393 x 10^24 atoms of O?
70.45 g O
140.9 g O
63.58 mole O
63.58 g O

Answers

Answer:

63.58 g O

Explanation:

To calculate the mass of O atoms, the number of moles of O atoms are needed and can be calculated as follows:

n (no. of moles) = nA ÷ 6.02 × 10^23

n = 2.393 x 10^24 ÷ 6.02 × 10^23

n = 0.398 × 10^ (24-23)

n = 0.398 × 10^1

n = 3.98moles.

To calculate the mass of Oxygen, we use the following formula:

moles = mass/molar mass

Molar mass of O = 16.

3.98 = m/16

m = 3.98 × 16

m = 63.68grams of Oxygen.

Answer:

Solution given:

[tex]1 mole \:of O=6.023×10^{23} atoms[/tex]

1 mole of O =16g

we have

[tex] 6.023×10^{23} atoms\: of O=16g[/tex]

now

[tex] 2.393 × 10^{24} atoms\: of \:O\\=16/6.023×10^{23}*2.393 x 10^{24}g\\=63.57g[/tex]

63.57g is a required mass of O.

Calculate the concentration of hydrochloric acid if 50.0 mL of hydrochloric acid is neutralized by 25.0 mL of 2.0 M sodium hydroxide. The neutralization reaction is shown below HCl + NaOH > H2O + NaCl

Answers

Answer:

1.0M HCl is the concentration of the acid

Explanation:

Based on the reaction, 1 mole of NaOH reacts per mole of HCl. That means the moles added of NaOH in the neutralization = Moles of HCl in the solution. With the moles and the volume in Liters we can find the molar concentration of HCl

Moles NaOH = Moles HCl:

25.0mL = 0.025L * (2.0moles / L) = 0.050moles HCl

Molarity:

0.050moles HCl / 0.0500L =

1.0M HCl is the concentration of the acid

How many grams of glycerine, C3H8O3, are needed to make 100. mL of 2.60 M solution?

Answers

Answer:

the mass of the glycerine needed in the given solution is  23.92 g

Explanation:

Given;

molarity of the solution (C₃H₈O₃), C = 2.60 M

Volume of the solution, V = 100 mL = 100 x 10⁻³ L = 0.1 M

The molarity of a solution is given as follows;

[tex]Molarity = \frac{amount \ of \ solute \ (moles)}{volume \ of \ solution \ (L)} \\\\amount \ of \ solute \ (moles) = Molarity \ \times volume \ of \ solution \ (L)\\\\amount \ of \ solute \ (moles) = 2.6 \times 0.1 \\\\amount \ of \ solute \ (moles) = 0.26 \ mole[/tex]

The molecular mass of the given solution;

molecular mass = (12 x 3) + (8 x 1) + (16 x 3)

molecular mass = 92 g/mol

The mass of the glycerine needed in the given solution is calculated as follows;

reacting mass = amount of solute (moles)   x   molecular mass (g/mol)

reacting mass = 0.26 x 92

reacting mass = 23.92 g

Therefore, the mass of the glycerine needed in the given solution is  23.92 g

Fluorine gas a 300 K occupies a volume of 500 mL. To what temperature should it be lowered to bring the volume to 300 mL?

Answers

180 K

V1/T1 = V2/T2
V1 = 500 mL
T1 = 300 K
V2 = 300 mL

Solve the equation for T2 —> T2 = V2T1/V1

T2 = (300 mL)(300 K) / (500 mL) = 180 K

The temperature should be lowered to 300K to bring the volume to 300mL.

What is temperature?

Temperature is the degree of hotness or coldness of a place or a body. The SI unit of temperature is Kelvin.

What is volume?

Volume is the amount of space occupied by matter. The SI unit of volume is cubic metre.

Using Charles law,

V1/V2 = T1/T2

Where, V1 and T1 are the initial volume and temperature

Similarly, V₂ and T₂ are the final volume and temperature.

Given:

V1 = 500mL

T1 = 300K

V2 = 300mL

T2 = ?

V1T2/V1 = V2T1/V1

          T2 = V2T1/V1

                = 300mL x 300K/500mL

           T2 = 180K

Hence, the temperature should be lowered to 300K to bring the volume to 300mL.

Answers

Answer:

[tex]\Delta G_{rxn}=51.0kJ/mol[/tex]

Explanation:

Hello there!

In this case, according to the definition of the Gibbs free energy of reaction in terms of the Gibbs free energy of formation of the involved reactants and products, it is possible for us to compute it as shown below:

[tex]\Delta G_{rxn}=3\Delta _f G_{NO_2}+\Delta _f G_{H_2O}-2\Delta _f G_{HNO_3}-\Delta _f G_{NO}[/tex]

Thus, by plugging in the given data, it is possible to obtain:

[tex]\Delta G_{rxn}=3(51.3)+(-237.1)-2(-110.9)-(87.6)\\\\\Delta G_{rxn}=51.0kJ/mol[/tex]

Best regards!

The standard Gibbs free energy change (ΔG°rxn) for the reaction is 76.7 kJ/mol.

The balanced equation for the reaction is:

2 HNO₃(aq) + NO(g) → 3 NO₂(g) + H₂O(l)

The standard free energy change for a reaction ( ΔG0rxn) can be found out using the equation,

ΔG° = Σ ΔG°fproducts - Σ ΔGf° ​​​​​reactants

ΔG°rxn = ΔH°rxn - TΔS0rxn  

∆H°rxn = change in enthalpy of reaction

∆S° = Change in entropy of reaction

T = Temperature ( 298 K )

ΔG°rxn = (3 × ΔG°f(NO₂(g)) + ΔG°f(H₂O(l))) - (2 × ΔG°f(HNO₃)aq)) + ΔG°f(NO(g)))

Substituting the given ΔG°f values:

ΔG°rxn = (3 × 51.3 kJ/mol) + (-237.1 kJ/mol) - (2 × (-110.9 kJ/mol)) + (87.6 kJ/mol)

ΔG°rxn = 153.9 kJ/mol - 237.1 kJ/mol + 221.8 kJ/mol + 87.6 kJ/mol

ΔG°rxn = 226.2 kJ/mol - 149.5 kJ/mol

ΔG°rxn = 76.7 kJ/mol

Which solution is more concentrated?
0.5 M NaCl
0.005 M NaCl
0.05 M Nacl
5.0 M NaCl

Answers

Answer: 5.0 M NaCl

Explanation:

A concentrated solution is one which has more amount of solute in it.

A dilute solution is one which has less amount of solute in it.

Molarity is defined as the number of moles of solute present per liter of the solution.

0.5 M NaCl will have 0.5 moles of NaCl in 1 L of the solution, 0.005 M NaCl has 0.005 moles of NaCl in 1 L of the solution, 0.05 M NaCl has 0.05 moles of NaCl in 1 L and 5.0 M NaCl has 5 moles of NaCl in 1 L.

Thus 5.0 M NaCl will be most concentrated.

A gas at a temperature of 300 K occupies a 5 L flexible container at a pressure of 150 kPa. What volume will it occupy at STP?

Answers

6.73 L

This one requires the combined gas law.

P1V1/T1 = P2V2/T2

P1 = 150 kPa = 1.48 atm

V1 = 5 L

T1 = 300 K

P2 = 1 atm

V2 = This is what we’re solving for.

T2 = 273 K

P2 and T2 are based on the conditions of STP. I also changed P1 to atm to keep the units consistent.

Solve the equation for V2:

V2 = P1V1T2 / T1P2

V2 = (1.48 atm)(5 L)(273 K) / (300 K)(1 atm) = 6.73 L

A 25.0 mL sample of HCI reacted with 20.0 mL of 2.00 M NaOH. What is the molarity of the HCI?
HCl(aq) + NaOH(aq) —> NaCl(aq) + H2O(l)
really need help!

Answers

Answer:

Molarity of HCl = 1.6M

Explanation:

The chemical reaction equation is;

HCl(aq) + NaOH(aq) —> NaCl(aq) + H2O(l)

Now, molarity = number of moles/volume

Thus, for NaOH, we have;

Number of moles = molarity × volume = 2M × (20/1000) L

Number of moles = 0.04 moles

Using the coefficients in the chemical equation above, we can find the corresponding number of moles for HCl.

Number of moles of HCl = 0.04 moles NaOH × (1 mole of HCl/1 mole of HCl) = 0.04 moles of HCl

Thus;

Molarity of HCl = 0.04/(25/1000)

Molarity of HCl = 1.6M
