2. 229/90 Th -> 4/2 He + ______
3. 20/8 O -> 20/9F + ________
4. 54/26Fe + 1n -> 1H + _______
5. 104/47Ag -> 0/-1e + ______
6. ________ + 0/-1e -> 54/24Cr
7. 238/92U + 12/6C -> 246/98Cf + ______
8. ________ + 0/-1 -> 207/82Pb
Look at your post under Alexus. We prefer you stick to the screen same name.
God bless you all :) <3 :)
To balance nuclear equations, you need to ensure that the number of protons and neutrons on both sides of the equation is equal. Here's a step-by-step guide on how to balance these nuclear equations:
1. 35/17Cl + 1n -> 35/16S + _____
In this equation, we see that the number of nucleons (protons + neutrons) on the left side is 18 (17 protons + 1 neutron), while on the right side, it is 35 (16 protons + 19 neutrons). To balance the equation, you need to add 17 neutrons to the right side:
35/17Cl + 1n -> 35/16S + 17n
2. 229/90Th -> 4/2He + ______
This equation is already balanced because the total number of nucleons on the left side (229) is the same as on the right side (4 + 225).
3. 20/8O -> 20/9F + ________
For this equation, we observe that the number of nucleons on the left side is 28 (8 protons + 20 neutrons), while on the right side, it is 29 (9 protons + 20 neutrons). To balance the equation, you need to add a neutron on the left side:
20/8O + 1n -> 20/9F
4. 54/26Fe + 1n -> 1H + _______
In this equation, the number of nucleons on the left side is 55 (26 protons + 29 neutrons), while on the right side, it is 2 (1 proton + 1 neutron). To balance the equation, you need to subtract 53 from the right side and add 53 to the left side:
54/26Fe + 1n -> 1H + 53/24Cr
5. 104/47Ag -> 0/-1e + ______
This equation is already balanced because the total number of nucleons on the left side (104) is the same as on the right side (0 + 104).
6. ________ + 0/-1e -> 54/24Cr
To balance this equation, we need to add a positron (e+) on the left side to balance the electron (e-) on the right side:
1e+ + 0/-1e -> 54/24Cr
7. 238/92U + 12/6C -> 246/98Cf + ______
In this equation, the number of nucleons on the left side is 250 (92 protons + 158 neutrons), while on the right side, it is 246 (98 protons + 148 neutrons). To balance the equation, you need to subtract 4 neutrons from the left side and add 4 neutrons to the right side:
238/92U + 12/6C -> 246/98Cf + 4n
8. ________ + 0/-1 -> 207/82Pb
To balance this equation, we need to add a positron (e+) on the left side to balance the electron (e-) on the right side:
1e+ + 0/-1 -> 207/82Pb
Remember that balancing nuclear equations relies on maintaining the conservation of mass and charge. By ensuring the total number of nucleons (protons + neutrons) and the total charge remains the same on both sides, you can balance the equation.
