Which statement describes the stability of the nuclei of potassium atoms

Answers

Answer 1

Answer:

The potassium nuclei have been unstable and results in the spontaneous decay without any external force. Thus, option 3 is correct.

Potassium has been the metal of group 1 of the periodic table. It has been consisted of 19 protons and 20 neutrons in the nucleus.

Decay of potassium nuclei

The nuclei decay has been achieved when there has been loss of the protons in the nuclei, resulting in the radioactive isotopes.

The potassium nuclei have been unstable and results in the spontaneous decay without any external force. Thus, option 3 is correct.

Answer 2

Answer: Which statements?

In general though, the potassium atom has 19 protons, and has 1 valence electron in the 4s orbital. The nucleus of the atom contains 19 protons and (21 neutrons on average.) If we were too apply the laws regarding the band of stability then that ratio is very stable and it is very unlikely (less than 10^-21%) that the nucleus would ever go through any form of decay.

A chemist has dissolved a certain substance in water the chemist knows that more of the substance could be dissolved into the water before it stops dissolving there for the current solution is a.) unsaturated b.) saturated c.) supersaturated

Answers

b.) Unsaturated... Because it can take on more.

If it can't take on more, it's saturated. If it takes more than it can hold, it's supersaturated.

Answer:

unsaturated :)

It is possible for the mass of the reactants to be greater than the mass of the products during _________.a. phase changes
b. fusion reactions
c. fission reactions
d. physical reactions E. chemical reactions

Answers

The correct answer is B. It is possible for the mass of the reactants to be greater than the mass of the products during fusion reactions. The mass of the products is less than the mass of the reactants because some of the mass has been converted to energy. Fusion reaction happens when two or more nuclei combine or collide to form an element with a higher atomic number. In this process, some of the matter of the fusing nuclei is converted to energy.

The density of nitroglycerine is 1.60 g/ml what is the volume in liters of a mole of liquid nitroglycerine

Answers

To be able to calculate the volume, we need the data on the molar mass and density of the substance nitroglycerine. The molar mass of nitroglycerine is 227.09 g/mol. We calculate as follows:

1 mol ( 227.09 g/mol) ( 1 mL / 1.60 g ) = 141.93 mL
