Which of the following is not a balanced nuclear equation?

Chemistry

Answer:

¹⁰₄Be —> ¹⁰₃Li + ⁰₋₁β

Explanation:

To know which equation is unbalanced, we shall compare the mass number and atomic number of the reactant and product together. This is illustrated below:

¹²¹₅₀Sn —> ⁰₋₁β + ¹²¹₅₁Sb

121 = 0 + 121

121 = 121

50 = –1 + 51

50 = 51

Thus the above equation is balanced

¹⁹⁰₇₈Pt —> ¹⁸⁶₇₆Os + ⁴₂α

190 = 186 + 4

190 = 190

78 = 76 + 2

78 = 78

Thus, the above equation is balanced

¹⁰₄Be —> ¹⁰₃Li + ⁰₋₁β

10 = 10 + 0

10 = 10

4 = 3 + (–1)

4 = 3 – 1

4 = 2

Thus, the above equation is unbalanced.

²³⁸₉₂U —> ⁴₂α + ²³⁴₉₀Th

238 = 4 + 234

238 = 238

92 = 2 + 90

92 = 92

Thus, the above equation is balanced.

From the illustrations made above, only ¹⁰₄Be —> ¹⁰₃Li + ⁰₋₁β

Is unbalanced.

Which phase change represents a decrease in entropy?(1) solid to liquid (3) liquid to gas(2) gas to liquid (4) solid to gas
emmainna [20.7K]

Answer : The correct option is, (2) gas to liquid

Explanation :

Entropy : It is defined as the measurement of randomness or disorderedness in a system.

The order of entropy will be,

As we are moving from solid state to liquid state to gaseous state, the entropy will be increases due to the increase in the disorderedness.

As we are moving from gaseous state to liquid state to solid state, the entropy will be decreases due to the decrease in the disorderedness.

In option 1, 3 and 4, the entropy increases. while in option 2, the entropy decreases.

Hence, the correct option is, (2) gas to liquid
