Answer:
A.
Explanation:
In the case of a seesaw, the object at the top is the effort and the object at the bottom is the load.
Taking into account the change of units, 21.8 in³ is equal to 0.357238 L.
<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, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , 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>in³ to liters</h3>
To perform in this case the conversion of units, you must first know that 1 in³ = 0.0163871 L. So, the rule of three can be used as follow: if 1 in³ is 0.0163871 L, 21.8 in³ equals how many L?
1 in³ ⇒ 0.0163871 L
21.8 in³ ⇒ x
So: x= (21.8 in³ ×0.0163871 L)÷ 1 in³
Solving:
<u><em>x= 0.357238 L</em></u>
In summary, 21.8 in³ is equal to 0.357238 L.

Answer:
Energy is used to break bonds in reactants, and energy is released when new bonds form in products. ... In other chemical reactions, it takes more energy to break bonds in reactants than is released when bonds form in products. These reactions, called endothermic reactions, absorb energy.
