<u>Answer:</u> The Einstein's equation is given below.

<u>Explanation:</u>

Nuclear reactions are defined as the reaction in which an alteration in nucleus of an atom takes place. There are two types of nuclear reactions: Nuclear fusion and nuclear fission reactions.

The equation given by Albert Einstein for nuclear reaction is given by:

E = mc^2

where,

E = Energy

m = Mass

c = Speed of light

Hence, the Einstein's equation is given above.

I would say it should be Einstein's famous equation of e=mc^2 which means energy =mass x the speed of light squared. With this equation Einstein showed that energy comes from a mass travelling at the speed of light squared which is a fundamental equation to explain physical phenomena.

Answer:

1. 22 moles of FeCr2O7

2. 53.95 moles of O2

3. 77.25 moles of O2

Explanation:

4 FeCr2O7+ 8 K2CO3 + 1 O2-----------> 2 Fe2O3+ 8 K2CrO4 + 8 CO2

1. How many moles of FeCr2O7 are required to produce 44 moles of CO2?

Equate the moles of the compounds in the question

4 moles of FeCr2O7 produces 8 moles of CO2

(44 *4 / 8) moles of FeCr2O7 will produce 44 moles of CO2

= 44 *4 / 8

= 22 moles

2. How many moles of 02 is required to produce 107.9 moles of Fe2O3?

1 mole of O2 = 2 moles of Fe2O3

(107.9 *1 / 2) moles of O2 will be required to produce 107.9 moles of Fe2O3

= 107.9 * 1 / 2

= 53.95 moles

3. The ratio of moles for FeCr2O7 to O2 in the reaction is

4 : 1

309 : x ; solve for x

x = 309 * 1 / 4

x =77.25 moles of O2
