Interpretation:
The correct expression of mole ratio needs to be explained when it is used to solve the stoichiometric problem.
Concept introduction:
The ratio of amount of any two compounds involved in a

Explanation of Solution
From the balanced chemical equation for a chemical reaction, a mole ratio is determined. The correct expression for the mole ratio will have number of moles of unknown substance in the numerator whereas the number of moles of known substance in the denominator of the ratio.

Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. ?

H3O+ If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. 0 If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank. فا Explanation Check Click and drag to start drawing a structure.arrow_forward
