Help pls! Which of the following shows a balanced nuclear reaction?

Option 4: ¹⁴₆C —> ⁰₋₁e + ¹⁴₇N

Explanation:

To know which option is correct, do the following:

Option 1:

²²¹₈₇Fr —> ⁴₂He + ²²⁵₈₅At

87 = 2 + 85

87 = 87

221 = 4 + 225

221 ≠ 229

Thus the equation is not balanced.

Option 2:

²³⁷₉₃Np —> ⁴₂He + ²³³₉₅Am

93 = 2 + 95

93 ≠ 97

237 = 4 + 233

237 = 237

Thus, the equation is not balanced.

Option 3:

²¹⁴₈₂Pb —> ⁰₋₁e + ²¹⁴₈₁Tl

82 = –1 + 81

82 ≠ 80

214 = 0 + 214

214 = 214

Thus, the equation is not balanced.

Option 4:

¹⁴₆C —> ⁰₋₁e + ¹⁴₇N

6 = –1 + 7

6 = 6

14 = 0 + 14

14 = 14

Thus, the equation is balanced.

From the illustrations above, only option 4 is correct.

wher is the rest of the question

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
