The <span>roles of products, reactants, and limiting reactant are significant in order for a chemical reaction to take place. The reactants are the components that are interacted in such a way that it would eventually produce a product, while on the other hand, a limiting reactant is used to regulate the products intended to produce.</span>
The work done on the filled bucket in raising out of the hole is 2, 925 Joules
<h3>How to determine the work done</h3>
Using the formula:
Work done = force * distance
Note that force = mass * acceleration
F = mg + ma
F = 4. 5 * 10 + 28 * 10
F = 45 + 280
F = 325 Newton
Distance = 9m
Substitute into formula
Work done = 325 * 9
Work done = 2, 925 Joules
Therefore, the work done is 2, 925 Joules
