Would you expect a Boron (B) atom with atomic mass = 9.999 to be stable?

Answers

The balance of forces allows to find the result for the question if the isotope of boron 9.99 una  is stable:

The boron isotope of mass 9.99 uma is unstable because the repulsive force increases.

The stability of atomic nuclei depends on the balance the force is electrostatic repulsion between the protons and the strong interaction of attraction.

One way to achieve this balance is to increase the separation of the protons with uncharged particles between them, the neutral ones, the strong interaction is of the same magnitude for protons and neutrons, therefore the repulsion is decreased and the strong attraction interaction is maintained. .

In the case of Boron, which has 5 protons, the stable structures have more atomistic 10 and 11 una, which is why it has 5 and 6 neutrons each. Therefore each proton has  a neutrons next to it and in the other case a proton at the end has two neutrons, this causes the distance between the protons to increase, decreasing the electrostatic repulsion.

It indicates that we have a Boron nucleus of mass 9.999. The number of protons must remain fixed, therefore there are only 4 neutrons.

Consequently, some of the protons does not have a neutron next to it and can approach the other proton, therefore the electrostatic repulsion increases and the stability of the atom decreases.

In conclusion, using the balance of Forces we can find the result for the question if the isotope of boron 9.99 una is stable:

The boron isotope of mass 9.99 amu is unstable because the repulsive force increases.

Which one item of the list below does not describe part of beta decay?
A. The nucleus of the atom is unstable.
B. A neutron turns into a proton.
C. A proton turns into an electron.
D. An electron is ejected from the nucleus.

Answers

Answer:

C

Explanation:

When Beta decay happens, the atomic number of an element goes up, and that means there is an extra proton. A is not the answer because unstable atoms cause decay. B is also not correct because this is what happens in Beta decay: a neutron becomes a proton. D is not correct because an electron is actually emitted from the nucleus.

Answers

Question:-

flowering plants are called?

Answer:-

Angiosperms

Explanation:-

Angiosperms are plants that bloom and bear fruit. The word angiosperm is derived from two Greek words, Angeion and Sperma . Angeion means "vessel" and sperma means "seed".

A flexible vessel contains 78.00 L of gas at a pressure of 1.50 atm. Under conditions of constant temperature
and moles of gas, what is the pressure of the gas when the volume of the vessel is tripled?

Answers

The pressure of the gas when the volume of the vessel is tripled is 0.50 atm.

To find the volume of the gas, we use Boyle's law which states that for a given mass of gas at constant temperature, the pressure is inveresly proportional to its volume. This is stated mathematically as P ∝ 1/V.

So, PV = constant

P₁V₁ = P₂V₂ where P₁ = initial pressure of gas = 1.50 atm, P₂ = final pressure of gas, V₁ = initial volume of gas = 78.00 L and V₂ = final volume of gas = 3V₁ (since the volume of the gas is tripled)

So, making P₂ the subject of the formula, we have

P₂ = P₁V₁/V₂

Substituting the values of the variables into the equation, we have

P₂ = P₁V₁/V₂

P₂ = 1.50 atm × V₁/3V₁

P₂ = 1.50 atm/3

P₂ = 0.50 atm

So, the pressure of the gas when the volume of the vessel is tripled is 0.50 atm.

Answers

Answer:

The correct answer choice is A. A chemical change has occurred because new compounds have been produced.

Explanation:

A physical change is defined as a change in which there is alteration in shape, size etc. No new substance gets formed in these reactions.Example: Melting of ice A chemical change is defined as a change in which a change in chemical composition takes place. A new substance is formed in these reactions.Example: photosynthesis

Photosynthesis is the process used by plants, algae and certain bacteria to convert energy from sunlight and turn it into chemical energy in the form of glucose which is used a s a source of energy by many organisms.

Thus the true statement is a chemical change has occurred because new compounds have been produced.

A student borrows $10,000 from a bank but ends up paying $13,000 on the

loan over the next five years. How much interest did the student pay?

Answers

The student paid an interest of $3,000 over the next five years.

HOW TO CALCULATE INTEREST:

The interest on a borrowed amount of money can be calculated by subtracting the principal from the amount paid over time. That is;

Interest = principal - amount

According to this question, a student borrows $10,000 from a bank but ends up paying $13,000. This means that the principal is $10,000 while the amount is $13,000. The interest is calculated thus;

Interest = $13,000 - $10,000

Interest = $3,000

Therefore, the student paid an interest of $3,000 over the next five years.

Lithium has an atomic mass of 6.941 amu. Lithium has two isotopes. One isotopes has a mass of 6.015 amu with a relative abundance of 7.49%. What is the mass of the other isotopes?

Answers

Explanation:

List the known and unknown quantities and plan the problem. Change each percent abundance into decimal form by dividing by 100. Multiply this value by the atomic mass of that isotope. Add together for each isotope to get the average atomic mass.

Answer:

The atomic mass of second isotope is 7.016

Explanation:

Given data:

Average Atomic mass of lithium = 6.941 amu

Atomic mass of first isotope = 6.015 amu

Relative abundance of first isotope = 7.49%

Abundance of second isotope = ?

Atomic mass of other isotope = ?

Solution:

Total abundance = 100%

100 - 7.49 = 92.51%

percentage abundance of second isotope = 92.51%

Now we will calculate the mass if second isotope.

Average atomic mass of lithium = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

6.941 = (6.015×7.49)+(x×92.51) /100

6.941 =  45.05235 + (x92.51) / 100

6.941×100 = 45.05235 + (x92.51)

694.1 - 45.05235   = (x92.51)

649.04765 = x 92.51

x = 485.583 /92.51

x = 7.016

The atomic mass of second isotope is 7.016
