Which answer choice best explains why nuclear reactions release more energy than chemical reactions?

Answers

The amount of energy release a reaction is depended on how strong the binding energy hold the particles together

In nuclear reaction, they're breaking nucleus bind apart , which create a huge amount energy that cause by the separation of the bind. The amount is far greater than in chemical reaction which only separate the binds of electrons.

Explanation:

The Haber process can be used to produce ammonia (NH3) from hydrogen gas (H2) and nitrogen gas (N2). The balanced equation for this process is shown below.3H2 + N2 mc025-1.jpg 2NH3

The molar mass of NH3 is 17.03 g/mol. The molar mass of H2 is 2.0158 g/mol. In a particular reaction, 0.575 g of NH3 forms. What is the mass, in grams, of H2 that must have reacted, to the correct number of significant figures?
0.1
0.102
0.10209
0.1021

Answers

Answer : The mass of H_2 in grams is 0.102g.

Solution : Given,

Molar mass of NH_3 = 17.03 g/mole

Molar mass of H_2 = 2.0158 g/mole

Given Mass of NH_3 = 0.575 g

First we have to calculate the moles of NH_3.

\text{ Moles of }NH_3=\frac{\text{ Given mass of }NH_3}{\text{ Molar mass of }NH_3} = (0.575g)/(17.03g/mole) = 0.0337 moles

The given balanced equation is,

3H_2(g)+N_2(g)\rightarrow 2NH_3(g)

From the above reaction, we conclude that

2 moles of NH_3 produced from 3 moles of H_2

then the 0.0337 moles of NH_3 produces to give (3moles* 0.0337moles)/(2moles) moles of H_2

The moles of H_2 = 0.0505 moles

The mass of H_2 = Moles of H_2 × Molar mass of H_2 = 0.0505 moles × 2.0158 g/mole = 0.10179 g

The mass of H_2 in the correct number of significant figures is 0.102 g.
