Problem Set 4

Though there are technically only 13 questions on this exam, they take up six pages and make a thorough assessment of organic chemistry principles. There are plenty of diagrams to label or complete. Emission spectra are displayed for...

Who knew F=MA could determine the force of a free-falling elevator? Give your class this set of thirteen word problems for practice determining force, mass, and acceleration of everyday objects. One question introduces an object in a...

In this organic chemistry practice instructional activity, students solve twelve problems regarding organic molecules. They draw mechanisms for reactions, they predict products for reactions, they label stereocenters and they identify...

Young biochemists examine the reactions that make life possible with this set of practice problems. Focusing specifically on carbohydrate compounds, these multi-step questions challenge students to demonstrate their understanding of the...

Three pedigrees are presented for junior geneticists to interpret. Then, a double strand of DNA is printed for them to analyze. Hypothetical animal crosses are described, from which learners determine the genotypes and phenotypes of the...

All units and significant figures should be used correctly as part of this check on molar mass calculations.  These word problems range in complexity and present the missing variable in different ways. Your young scientists might enjoy...

In this organic chemistry of alkynes worksheet, students write products for reactions in 9 equation problems. They show the synthesis steps for 3 reactions and write the names for 3 compounds.

The reaction of Phosphorus and Chlorine is the focus of this video on Stoichiometry. Sal sets up a reaction between the two substances, and uses the process of Stoichiometry in order to calculate how many grams of Phosphorus Trichloride...

Another problem from a chemistry textbook is utilized to illustrate the concept of Limiting Reactants. Sal sets up a reaction between carbon monoxide and hydrogen in order to produce methanol - which is the fuel used in race car engines....

Sal continues his explanation of The Ideal Gas Equation in this chemistry video. He sets up a different problem from the previous video, and uses the ideal gas equation to calculate the molar mass of a 98 ml container that contains .081...
