Calculate the number of grams in each of the following: 0.520 mole NaCl 1.80 moles Na2C 0.250 mole H2O 4.10 moles CO2
Recrystallization from 95% ethanol gave yellow crystals. What is the overall mechanism for this reaction including all arrows, the identification of the electrophile and nucleophile, and all charges?
Calculate the vapor pressure of a solution containing 29.4 g of glycerin (C3H8O3) in 120 mL of water at 30.0 C. The vapor pressure of pure water at this temperature is 31.8 torr
Although the term "melting point" is used to describe a solid/ liquid change, we generally list melting ranges rather than single melting point. For most pure substances,
extremely high-purity silicon is required to manufacture semiconductors such as the memory chips found in calculators
What is the Zn2+: Cu2+ concentration ratio in the following cell 25 degrees if the measured cell potential

The engine stops working when the temperature of the hot reservoir has been lowered to TC. Show that the amount of work done by the engine is W = C1(TH-TC) - C1TC ln (TH/TC).
When halogens react they tend to gain electrons rather than lose electrons. Pick the best two reasons why this occurs.
