A particular forest is 10,000 acres. Determine its size in hectares. (1 hectare = 2.47
igor_vitrenko [27]

Taking into account the change of units, a particular forest is 4,048.58 hectares.

<h3>Definition of rule of three</h3>

The rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, the direct rule of three must be applied using the following formula, where a, b and c known data and x the variable to be calculated:

a ⇒ b

c ⇒ x

So: x= (c×b)÷ a

The direct rule of three is the rule applied in this case where there is a change of units.

<h3>Size in hectareas</h3>

To perform in this case the conversion of units, you must first know that 1 hectare = 2.47 acres.

So, the rule of three can be used as follow: if 2.47 acres is 1 hectare, 10,000 acres equals how many hectares?

2.47 acres ⇒ 1 hectare

10,000 acres ⇒ x

So: x= (10,000 acres ×1 hectare)÷ 2.47 acres

Solving:

<u><em>x= 4,048.58 hetares</em></u>

In summary, a particular forest is 4,048.58 hectares.

Which statement is true about limiting reactants?
Paraphin [41]

Answer:

The limiting reactant in a reaction is the first reactant to be completely converted to products.

Explanation:

When we perform a reaction, it is not easy to measure the exact amount of the two reagents to make sure that both of them react completely. That's why typically we have a limiting reagent and a reagent in excess.

The limiting reagent is the one which determines the maximum amount of product formed, as when it's used up, the reaction stops and cannot proceed further, since the other reagent doesn't have anything to react with.

Simply speaking, the limiting reactant in a reaction is the first reactant to be completely converted to products.

The limiting reagent provides the information about the amount of the product formed, as opposed to the reagent in excess which doesn't provide any valuable information.
