the nuclear mass of ba141 is 140.883 amu. calculate the binding energy per nucleon for ba141 .

Answers

Answer 1

To calculate the binding energy per nucleon for Ba141, we need to first determine the total binding energy for the nucleus. The total binding energy can be calculated by subtracting the total mass of the nucleons from the actual mass of the nucleus. The mass of the nucleons is calculated by multiplying the mass of a proton by the number of protons and the mass of a neutron by the number of neutrons.

The mass of Ba141 is 140.883 amu. Since the atomic number of Ba is 56, it has 56 protons. To find the number of neutrons, we subtract the atomic number from the mass number, which gives us 85 neutrons.

The mass of a proton is 1.0073 amu, and the mass of a neutron is 1.0087 amu. Therefore, the total mass of the nucleons is (56 x 1.0073) + (85 x 1.0087) = 140.180 amu.

To calculate the binding energy, we subtract the mass of the nucleons from the actual mass of the nucleus, which is 140.883 - 140.180 = 0.703 amu.

The binding energy per nucleon can be found by dividing the binding energy by the number of nucleons. Ba141 has 141 nucleons, so the binding energy per nucleon is 0.703 / 141 = 0.005 amu.

Therefore, the binding energy per nucleon for Ba141 is 0.005 amu.

PLEASE HELP ANSWER ALL PARTS!!!

Answers

Answer:

The student should have multiplied the molar mass, which was not found, by the number of moles to get an answer of 925grams of Ca(OH)2.

Please find the correct step below

Explanation:

According to the question attached, the student was asked to find the mass in grams of a 12.5mol of Ca(OH)2.

Using the formula;

mole = mass ÷ molar mass

Molar mass of Ca(OH)2 = 40 + (16 + 1)2

= 40 + 17(2)

= 40 + 34

= 74g/mol

From the above formula;

Mass in grams = mole × molar mass

Mass (g) = 12.5 × 74

Mass (g) = 925grams of Ca(OH)2.

How many molecules are in 7.9 mol of H202

Answers

Answer: There are [tex]47.6\times 10^{23}[/tex] molecules in 7.9 mol of [tex]H_2O_2[/tex]

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

1 mole of [tex]H_2O_2[/tex] molecule contains = [tex]6.023\times 10^{23}[/tex]  molecules

Thus 7.9 mole of [tex]H_2O_2[/tex] molecule contains = [tex]\frac{6.023\times 10^{23}}{1}\times 7.9=47.6\times 10^{23}[/tex] molecules

Thus there are [tex]47.6\times 10^{23}[/tex] molecules in 7.9 mol of [tex]H_2O_2[/tex]

What are significant figures?

The number that is given as digits is established using significant figures. A significant depiction of numbers is carried by these digits. Frequently, significant numbers are employed in place of figures. By counting all of the values beginning with the first non-zero digit on the left, we may determine the number of significant digits. 13.56, for instance, has four significant digits.

The crucial or key digits that accurately represent the meaning of a certain number are known as the significant figures of that number. 7.864 contains four significant digits, for instance. These huge amounts give the accuracy of the numbers. Additionally, they are known as important digits.

Therefore, the correct options are B, C, and D.

Sharon puts a large pot of water on the stove to boil pasta. Then she starts to make a tomato sauce. When the sauce is cooking, she looks at the pot of water and thinks the water level is much lower than it was. How does this diagram of part of the water cycle help Sharon explain what happened to the pasta water?

Answers

Answer:

1. A

2. C

Explanation:

For the first question, we know that the water transformed into a gas. This fact eliminates choices C and D, primarily because they describe the change as "gas to liquid" instead of liquid to gas.

What separates B from A is that B is saying the liquid changed to a gas in response to sunlight, which is completely false and impertinent to the prompt.

A is the correct answer.

for the second question, we know that condensation causes clouds -- and that neither evaporation nor water vapor would clear clouds to make more of them, which eliminates choices B and D. Going back to condensation, the accumulation of water vapor plays a big role in the formation of clouds. While evaporation does play a part in [it] as well, condensation is what caused the sudden appearance of clouds in the troposphere.

C is the correct answer.
