Let a, b, and c be the coefficients in the balanced reaction:
a Fe + b Cl₂ → c FeCl₃
Count the atoms that show up among the reactants and products. They should be equal on both sides:
Fe : a = c
Cl : 2b = 3c
Let c = 2. Then a = 2 and 2b = 6, so b = 3.
Then the balanced reaction is
2 Fe + 3 Cl₂ → 2 FeCl₃
The diameter and radius of a circle with circumference of 36 meters are 11.46 meters and 5.73 meters respectively.
<h3>How to find diameter and radius of a circle using circumference?</h3>
circumference of a circle is the perimeter of a circle. Therefore,
circumference of a circle = 2πr
where
Therefore,
36 = 2 × π × r
36 / 2 = πr
18 = πr
r = 18 / 3.14
r = 5.73248407643
radius = 5.73 meters
radius = diameter / 2
Therefore,
diameter = 2 × 5.73 = 11.46 meters
