calculate the minimum energy required to remove one proton from the nucleus 126c . this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c .)

Answers

Answer 1

939.067MeV is the energy required to extract a proton from a nucleus.

Calculation:

△m= mass of nucleus − mass of proton

= (mass of neutron + mass of proton) - mass of proton

= mass of neutron

= 1.008665amu

E=1.008665 X 931=939.067MeV

How are protons removed from the nucleus?

After absorbing a neutron, heavy nuclei can occasionally decay and turn into radioactive nuclei. A proton would ultimately be lost, along with perhaps one or two neutrons.

There are moles of carbon present in 100 g of a
compound with the following percentage composition:
C= 40.0%, H = 6.72%, O = 53.29%.

Answers

Answer: 3.33

Explanation:

The molecular formula of the given composition is C₃H₆O₃.

What is molecular formula?

Molecular formula is defined as a compound's chemical formula, which counts the total number of each element present in a molecule of the compound as discrete molecules. The arrangement of atoms in a molecule in three dimensions is known as molecular geometry, commonly referred to as the molecular structure.

The percentage composition is

C = 40.00 %

H = 6.72 %

O = 53.29 %

Mole = 100 g

Mass of C = 40 / 100 x 100 = 40 g

mass of H = 6.72 / 100 x 100 = 6.72 g

Mass of O = 53.29 / 100 x 100 = 53.29 g

Dividing the mass with moles

C = 40 / 12 = 3.3

H = 6.72 / 1 = 6.72

O = 53.29 / 16 = 3.3

Formula = C₃H₆O₃

Thus, the molecular formula of the given composition is C₃H₆O₃.

lol pls help me

Answers

Answer: 747.98 grams of KCl are made when 5.02 moles of  [tex]ZnCl_2[/tex] react in the reaction.

Explanation:

The balanced chemical equation is:

[tex]2KMnO_4+ZnCl_2\rightarrow 2KCl+Zn(MnO_4)_2[/tex]

According to stoichiometry:

1 mole of [tex]ZnCl_2[/tex] produce = 2 moles of [tex]KCl[/tex]

Thus 5.02 moles [tex]ZnCl_2[/tex] will produce =[tex]\frac{2}{1}\times 5.02=10.04[/tex] moles of [tex]KCl[/tex]

Mass of [tex]KCl=moles\times {\text {molar mass}}=10.04mol\times 74.5g/mol=747.98g[/tex]

Thus 747.98 grams of KCl are made when 5.02 moles of  [tex]ZnCl_2[/tex] react in the reaction.

A study was conducted to see if increasing the substrate concentration has an appreciable effect on the velocity of a chemical reaction. With a substrate concentration of 1.5 moles per liter, the reaction was run 15 times, with an average velocity of 7.5 micromoles per 30 minutes and a standard deviation of 1.5. With a substrate concentration of 2.0 moles per liter, 12 runs were made, yielding an average velocity of 8.8 micromoles per 30 minutes and a sample standard deviation of 1.2. Is there any reason to believe that this increase in substrate concentration causes an increase in the mean velocity of the reaction of more than 0.5 micromole per 30 minutes

Answers

Answer:

There is not enough evidence

Explanation:

For  1.5 moles substrate concentration per liter

Reaction ( n2 ) = 15 runs

average velocity ( x2 ) = 7.5 micromoles per 30 minutes

standard deviation ( s2 ) = 1.5

For 2.0 moles substrate concentration per liter

Reaction( n1 ) = 12 runs

average velocity ( x1 ) = 8.8 micromoles per 30 minutes

standard deviation ( s1 )  = 1.2

Show Reason to believe that this increase in substrate conc causes an increase in mean velocity

Hypothesis test

H0 : μ1 - μ2 = 0.5

H1 : μ1 - μ2  > 0.5

level of significance ( ∝ ) = 0.01

attached below is a detailed solution to the problem

P-value ( 0.073 ) > level of significance ( 0.01 ) hence we fail to reject the null hypothesis

hence there in not enough evidence to believe that this increase causes an increase in the mean velocity of the reaction of more than 0.5 micromole per 30 minutes

What is the new pressure if the temperature outside is 296k and his weight causes the tire's volume to drop to 2.0 liters

Answers

Question:

At standard temperature and pressure, the volume of a tire is 3.5L. What is the new pressure if the temperature outside is 296k and its weight causes the volume of the gas is 2.0 L?

Answer:

The new pressure is: 1.896 atm

Explanation:

At standard temperature and pressure, we have:

[tex]P_1 = 1atm[/tex]

[tex]T_1 = 273.15k[/tex]

[tex]V_1 = 3.5L[/tex]

Outside, we have:

[tex]T_2 = 296k[/tex]

[tex]V_2 = 2.0L[/tex]

Required

Determine the new pressure

Using combined gas law, we have:

[tex]\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}[/tex]

This gives:

[tex]\frac{1 * 3.5}{273.15} =\frac{P_2*2.0}{296}[/tex]

Solve for [tex]P_2[/tex]

[tex]P_2 = \frac{296 * 1 * 3.5}{273.15*2.0}[/tex]

[tex]P_2 = \frac{1036}{546.30}[/tex]

[tex]P_2 \approx 1.896 atm[/tex]

Answers

Answer:

See explanation

Explanation:

1 mole of Ne occupies 22.4 L

x moles of Ne occupies 18.6 L

x = 1 mole *  18.6 L/22.4 L

x = 0.83 moles

1 mole contains 6.02 * 10^23 atoms

0.83 moles occupies  0.83 moles *  6.02 * 10^23 atoms/1 mole

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
