3.47 x 1014)
4.82 x 1017]

Answer 1

Answer: The amount of energy released by the reaction is
`3.47* 10^(14)J`

Step-by-step explanation:

To calculate the energy released, we use Einstein equation, which is:

`E=\Delta mc^2`

where,

`\Delta m` = difference between the masses of products and reactants = 3.86 g = 0.00386 kg (Conversion factor: 1 kg = 1000 g)

c = speed of light =
`3* 10^8m/s`

Putting values in above equation, we get:

`E=(3.86* 10^(-3)kg)* (3* 10^8m/s)^2`

`E=3.47* 10^(14)J`

Hence, the amount of energy released by the reaction is
`3.47* 10^(14)J`
