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:
Explanation:
Given parameters:
Concentration of H₃O⁺ = 5.6 x 10⁻²M
Solution:
To solve for the concentration of H₃O⁺ in the solution, we simply use the expression below:
pH = -log₁₀[H₃O⁺]
where [H₃O⁺] = 5.6 x 10⁻²M is the concentration of H₃O⁺
pH = -log₁₀[5.6 x 10⁻²] = - x -1.25 = 1.25
it is defined as the ratio of moles of one substance to the moles of another substance in a balanced equation. To determine the mole ratio between two substances, all you need to do is look at the balanced equation for the coefficients in front of the substances you are interested in.
Answer:
Because Oxygen shares 2 electrons with mutual bond interaction forming covalent bond . thus it is diatomic due to K shell 2 electrons mutual sharing .
Explanation:
Answer: The new volume is 95.45 mL.
Explanation:
Given: 
= 45.0 mL, 
= 0.98 atm
= 2.1 atm, 
= ?
According to Boyle's law, at constant temperature the pressure of a gas is inversely proportional to its volume.
Therefore, formula used to calculate the new volume is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that the new volume is 95.45 mL.
