Answer:

Concept Formation

Explanation:

The formation of concepts is a process in which specific expressions are taken to make a generalization or a correspondence between things. The formation of concepts is very important in teaching because it is vital to acquire knowledge.

In this case, the fact that all 3-sided figures are triangles is an example of concept formation because a concept is a definition that helps us define if an object is within a certain category.

So for this example, the concept that every three-sided figure is a triangle can help us define when something can be classified or not as a triangle, thus falls into the category of concept formation.

Methyl salicylate (oil of wintergreen) is prepared by heating salicylic acid, , with methanol, . In an experiment, 1.60 g of sal
bekas [8.4K]

Answer:

90.71%

Explanation:

From the equation of reaction:

C_7H_6O_3 + CH_4O --> C_8H_8O_3

1 mole of salicylic acid requires 1 mole of methanol in order to produce 1 mole of methyl salicylate.

<em>mole = mass/molar mass</em>

1.6 g of salicylic acid = 1.6/138.121 = 0.012 moles

15 g of methanol = 15/32.04 = 0.47 moles

<em>Salicylic acid is the limiting reagent and hence, 0.012 moles of methyl salicylate would be produced according to the mole ratio above.</em>

0.012 moles of methyl salicylate = 0.012 x 152.1494 = 1.83 g

The theoretical yield of methyl salicylate is 1.83 g while the actual yield is 1.66 g.

<em>Percentage yield = actual yield/theoretical yield x 100%</em>

                         1.66/1.83 x 100% = 90.71%
