Which of the following nuclei would be the least stable

Chemistry

Nikitich [7]3 years ago

<h2>Answer:</h2>

The nuclei with <u>D. 1 proton and 2 neutrons</u> will be least stable.

<h2>Explanation:</h2>

Nuclides containing odd quantities of the two protons and neutrons are the least steady and this implies increasingly radioactive.  

Nuclides containing even quantities of the two protons and neutrons are most steady and this implies less radioactive.  

Nuclides contain odd quantities of protons (positive charged particles) and even quantities of neutrons are less steady than nuclides which are containing even quantities of protons and odd quantities of neutrons. By and large, atomic strength is more prominent for nuclides containing even quantities of protons and neutrons or both.

When we add 1 proton with 2 neutrons we get 3 as answer, which means an odd value, thus nuclide with this proportion of proton and neutron is least stable.

Answer:

C. 1 proton 3 neutrons

Explanation:

A nucleus is more stable if the ratio of the neutrons to protons is between 1:1 and 1:1.5.

Thus the ratios of neutrons to protons for  the nuclei are as follows

A- 1:1

B- 1:1

C- 1:3

D- 1:2

Among these ratios, C is the greatest thus the nucleus is the least stable.

Solution A has twice as much solute as solution B is it possible for the solutions to have the same concentration
pishuonlain [190]
Yes. As long as the ratio of solute and solvent is same for both solution, the solution has the same concentration. for example, solution A has 2 ml of water, and 1 ml of sucrose. Solution B has 4ml of water and 2ml of sucrose. Both has a ratio of water to sucrose by 2 : 1. they have the same concentration of 50% sucrose.

At STP, how many liters of oxygen are required to react completely with 3.6 liters of hydrogen to form water?
Delvig [45]
Should be 1.8L.
2 moles of hydrogen react with 1 mole of oxygen. If 2 moles of hydrogen is 3.6L, 1 mole of oxygen should be 1.8L.

explain why it is a common laboratory procedure to heat analytical reagents and store them in a dessicated atmosphere (a sealed
Readme [11.4K]

Explanation:

Most reagent forms are going to absorb water from the air; they're called "hygroscopic".  Water presence can have a drastic impact on the experiment being performed  For fact, it increases the reagent's molecular weight, meaning that anything involving a very specific molarity (the amount of molecules in the final solution) will not function properly.

Heating will help to eliminate water, although some chemicals don't react well to heat, so it shouldn't be used for all.  A dessicated environment is simply a means to  "dry."  That allows the reagent with little water in the air to attach with.
