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.
Answer:
38825.472 M
Explanation:
Using
C1V1=C2V2
To make solution B,
C1 = 25.527 M, V1 = 13 mL
C2 = 25.527 x 8 = 204.216 M
V2 = 13 X 12 = 156 mL
To make solution C'
C1 = 8 X 202.216 M = 1617.728
V1 = 8 X 156mL = 1248 mL
V2 = 4 X 13 = 52 mL
C2 = C1V1 / V2
=1617.728 X 1248 / 52
=38825.472 M
<h3>
Answer:</h3>
2 H₂ + O₂ → 2H₂O
<h3>
Explanation:</h3>
- The equation that shows the conservation of atoms is the balanced one.
- In this case, the balanced equation is;
2 H₂ + O₂ → 2H₂O
Because it has 4 hydrogen atoms and 2 oxygen atoms on both sides of the equation.
- Chemical equations are balanced to obey the law of conservation of mass that requires the mass of the reactant to be equal to the mass of the products.
- Balancing chemical equations makes the number of atoms of each element in the equation equal, thus conserving the mass in the chemical reactions.
