What are the coefficients of the compounds after balancing the following equation and what type of reaction is this?
1 answer:
The coefficient of Fe would be 2, the coefficient of Cl2 would be 3, while the coefficient of FeCl2 would be 2.
The balanced equation of the reaction would be as follows:
Thus, the coefficients of Fe, Cl2, and FeCl3 respectively would be 2, 3, and 2.
In other words, 2 moles of Fe require 3 moles of Cl2 to produce 2 moles of FeCl3 in a complete reaction.

Answer:
Explanation:
To determine the age, we need to know how much U have become Pb, so first we have to calculate the Pb moles present in a sample:
The percentage of U degradation:
Assuming that the life time is linear:
Answer : The number of moles of are 0.50 moles.
Solution : Given,
Volume solution = 0.25 L
Molarity of solution = 2.00 mole/L
Molarity : It is defined as the number of moles of solute present in one liter of solution.
Formula used :
Now put all the given values in this formula, we get number of moles.
By rearranging the term,
Number of moles of = 0.50 moles
Therefore, 0.50 moles of are there in the solution.
