Writing and Balancing Nuclear Equations
A nuclear equation is a symbolic representation of a nuclear reaction using certain symbols. It is studied in nuclear chemistry and nuclear physics.
Question
100%

Beginning with 100 g of iron-55, calculate how much remains after 7.7 years.  The half-life of iron-55 is 2.74 years.

Expert Solution

Introduction

The time taken during a reaction to reduce the concentration of a reactant to half of its initial value, is termed as half-life of the reaction. The half-life of a first order reaction is independent of the initial concentration of the reactant. 

Given data: 

Initial mass of iron-55 is 100 g 

Half-life of iron-55 is 2.74 years.
