Explanation:
During beta emission, neutrons are converted into protons and electrons. The anti neutrino balances the spins.
When a nucleus undergoes beta emission, the mass number of the daughter nucleus produced in the process is the same as that of the parent nucleus but the atomic number of the daughter nucleus increases by one unit.
The product of the beta decay of the nuclides shown in the question is described in the image attached to this answer.
<span>How does understanding the structure of the atom help you see both unity and diversity in forms of matter?</span><span>
Understanding the structure of the atom helps to understand unity in matter because all matter is made up of those very similar atoms. Understanding the structure of the atom helps to understand diversity in matter because matter can be different (solid, liquid, gas, hard, soft, etc) and knowing the structure of the atom can explain these differences.

Answer:
0.278 mol
Explanation:
Step 1: Given and required data
Mass of acetic acid (m): 16.7 g
Chemical formula of acetic acid: CH₃COOH (C₂H₄O₂)
Step 2: Calculate the molar mass (M) of acetic acid
We will use the following expression.
M(C₂H₄O₂) = 2 × M(C) + 4 × M(H) + 2 × M(O)
M(C₂H₄O₂) = 2 × 12.01 g/mol + 4 × 1.01 g/mol + 2 × 16.00 g/mol = 60.06 g/mol
Step 3: Calculate the number of moles (n) of acetic acid
We will use the following expression.
n = m/M
n = 16.7 g/(60.06 g/mol) = 0.278 mol
Answer:
One cubic centimeter is equal to one milliliter. Cubic centimeter is used interchangeably with millimeter. Centimeter belongs in the CGS unit system (centimeter-gram-second system) while liter belongs in the SI (Système International d'Unités) unit system. These two are equal.
