kari74 [83]

Answer: Option (D) is the correct answer.

Explanation:

In fusion reaction, two small nuclei combine together to result in the formation of a large nuclei.

Whereas in fission reaction, large nuclei dissociates into two or more small nuclei.

Nuclear fusion releases more energy as compared to nuclear fission.

For example, two hydrogen nuceli fuse together and result in the formation of helium atom along with release of energy.

Help!!!

Answer:

1. 0.82 gram of Ag+

2. 4.79 g of Ag₂O₃S

Explanation:

From the given information:

Total amount of Ag₂O₃S = 2.24 grams

Atomic mass of Ag+ =107.86 g/mole

molar mass of Ag₂O₃S = 295.8  g/mole

∴

The mass of the Silver (Ag) in grams is:

= Total\ amount \ of \ Ag^+ \times \dfrac{107.86 \ g/mol}{295.8 \ g/mol}

=2.24 \times \dfrac{107.86 \ g/mol}{295.8 \ g/mol}

= 0.82 gram of Ag+

2.

Here, the total amount of Ag₂O₃S = unknown

Atomic mass of Ag+ = 107.86 g/mole

molar mass of Ag₂O₃S = 295.8 g/mole

amount of Ag+  = 1.75 g

∴

The mass of Ag₂O₃S = Total \ amount \ of \ Ag^+ \times \dfrac{295.8 \ g/mol}{107.86\ g/mol}

=1.75  \times  \dfrac{295.8 \ g/mol}{107.86\ g/mol}

= 4.79 g of Ag₂O₃S
