Answer:

Option 3.

LiOH(aq) + HNO₃(aq) —> LiNO₃(aq) + H₂O(l)

Explanation:

To know which option is correct, we must have an ideal of what is acid–base neutralization.

Neutralization is a reaction involving an acid and a base which produces salt and water only.

With the above information, we can easily detect the equation describing acid-base neutralization reaction by considering the products of each reaction to see the one that has water as part of the products.

From the question given above, only the 3rd equation gas water as part of the products i.e

LiOH(aq) + HNO₃(aq) —> LiNO₃(aq) + H₂O(l)

Hence, equation 3 is an acid-base neutralization reaction

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.
