What is the most likely mode of decay for each?(c) ¹¹⁰₄₁4Ru
zmey [24]

The most likely mode of decay for a neutron-rich nucleus is one that converts a neutron into a proton.

<h3>What is radioactive decay?</h3>

The process through which an unstable atomic nucleus loses energy through radiation is known as radioactive decay, also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration. A substance that has unstable nuclei is regarded as radioactive. Alpha decay, beta decay, and gamma decay are three of the most frequent kinds of decay, and they all entail the emission of one or more particles. Beta decay is a result of the weak force, while the nuclear force and electromagnetism are in charge of the other two mechanisms. The capture of an inner electron from one of the electron shells by an unstable nucleus is the fourth prevalent form of decay.

Why h2o has higher boiling point than nh3
Hoochie [10]

Answer:

H2O molecules are thus able to form an average of 4 H-bonds. H2O has a higher boiling point than NH3 because (i) the H-bonds are stronger and (ii) it contains twice as many H-bonds. H2O has a higher boiling point than HF because it contains twice as many H- bonds, despite these being individually weaker.

Explanation:

You spill a little bit of olive oil on your hands. You wash off the oil with soap and water. How does the soap get the oil off y
Serhud [2]
It doesnt, soap is comprised of water, and water and oil do not have the same molarity, therefore do not mix and will just continue to rub oil on your hand but not come off

Calculate the number of grams of solute needed to make each of the following solutions:
AleksAgata [21]

Explanation:

(w/w) % : The percentage mass or fraction of mass of the of solute present in total mass of the solution.

w/w\%=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100

1) 100 g of 0.500% (w/w) NaI

Mass of solution = 100 g

Mass of solute = x

Required w/w % of solution = 0.500%

0.500\%=\frac{x}{100 g}\times 100

x=\frac{0.500\times 100 g}{100}=0.500 g

0.500 grams of solute needed to make 100 g of 0.500% (w/w) NaI.

2) 250 g of 0.500% (w/w) NaBr

Mass of solution = 250 g

Mass of solute = x

Required w/w % of solution = 0.500%

0.500\%=\frac{x}{250 g}\times 100

x=\frac{0.500\times 250 g}{100}=1.25 g

1.25 grams of solute needed to make 250 g of 0.500% (w/w) NaBr

3) 500 g of 1.25% (w/w) glucose

Mass of solution = 500 g

Mass of solute = x

Required w/w % of solution = 1.25%

1.25\%=\frac{x}{500 g}\times 100

x=\frac{1.25\times 500 g}{100}=6.25 g

6.25 grams of solute needed to make 500 g of 1.25% (w/w) (glucose)

4) 750 g of 2.00% (w/w) sulfuric acid.

Mass of solution = 750 g

Mass of solute = x

Required w/w % of solution = 2.00%

2.00\%=\frac{x}{750 g}\times 100

x=\frac{2.00\times 750 g}{100}=15.0 g

15.0 grams of solute needed to make 750 g of 2.00% (w/w) sulfuric acid.
