Answer:

E = 3.1885 E16 J

Explanation:

  • E = mc²

∴ c = 3 E8 m/s

∴ m = (2.53 E1)(14.003241 amu) = 354.282 g isotope

⇒ E = (354.282 g)(3 E8)²

⇒ E = 3.1885 E19 g.m²/s²

⇒ E = 3.1885 E16 Kg.m²/s² = 3.1885 E16 J

Answer : The amount of energy released is, 3.189\times 10^{16}J

Explanation :

Formula used to calculate the amount of energy released is:

E=mc^2

where,

E = amount of energy released

m = mass of isotope

c = speed of light = 3\times 10^8m/s

First we have to calculate the mass of isotope.

Mass of isotope = Moles of isotope × Atomic mass of isotope

Mass of isotope = (2.530 × 10)mol × 14.003241 amu

Mass of isotope = 354.3 g = 0.3543 kg

Now we have to calculate the amount of energy released.

E=mc^2

E=(0.3543kg)\times (3\times 10^8m/s)^2

E=3.189\times 10^{16}J

Thus, the amount of energy released is, 3.189\times 10^{16}J

<h2>Collision Theory </h2>

Explanation:

<h3>The given statement is related to the collision theory - </h3>

Collision theory was given by William Lewis in 1916.

This theory explains in a qualitative manner that in what way any chemical reaction occurs and the reason for the different reaction rates for different reactions.

<h3>According to the collision theory - </h3>
  • Molecules must collide in order to react
  • Sufficient amount of energy is needed for collisions (kinetic energy) so that the chemical bonds should break
  • This energy used is known as the activation energy
  • On the increase in the temperature, the kinetic energy of the molecule increases and the molecules move faster and collide with a proper orientation at an increased speed
  • This increases the rate of a collision that in turn increases the breaking of the bond

MariettaO [177]

Answer:

2.77532244 grams

Explanation:

Percent yeild=actual/theoretical * 100

Plug in the values

93.4452=actual/2.97 *100

0.934452*2.97=2.77532244
