Answer: For a. Mass number for the particle is 0.
For b. The charge on the particle is -1.
For c. Another name for 
- particle is electron.
Explanation:
Beta- minus decay is the decay process in which beta-particle is emitted. The mass number of the nuclei remains same and the mass number of the particle is 0. The charge on the particle is -1 and the emitted particle is also called as electron.
For a. The mass number for the particle is 0.
For b. The charge on the particle is -1.
For c. Another name for - particle is electron.
Answer:
55g NH₄Cl / 100g Water
Explanation:
Solubility of a substance define the amount of solute per solvent in a saturated solution. The solution can dissolve additional solute if heated.
In the problem, as the first crystal appears at 61°C the solubility in this temperature is the concentration of the solution, that is:
2,75g NH₄Cl / 5,0g water ₓ 100 = <em>55g NH₄Cl / 100g Water</em>
<em></em>
I hope it helps!
<span>The answer is B. Convection occurs when hot/warm
water rise to the top and the cold water goes to the bottom in a vessel. This is
because hot/warm water is less dense than cold water. Additionally, convection
currents are well perceptible in air and water and fluid substances that are
poor conductors of heat</span>
