From your understanding of collniative properties, how would you design an experiment to measure the freezing point of a material which freezes at -2degree celcius using the same apparatus used in the laboratory and chemical reagents commonly found in a chemical laboratory. Ice is the only material you have available to cool the solutions.
A.) If 75.0 g of sodium is mixed with 40.0 g of nitrogen gas, what mass of sodium nitride forms? B.) If the reaction in part A has a percent yield of 90 % , how much sodium nitride is actually produced

When 2-chloro-2-methylbutane is treated with a variety of strong bases, the products always seem contain two isomers (A and B) of formula C5H10.
If 160mL of wet H2 is collected over water at 24 degrees Celsius and a barometric pressure of 738torr , how many grams of Zn have been consumed
4388 M KOH solution reacts with 50.60mL of CH3COOH solution, what is the molarity of the acid solution?
Which of the available reagent(s), if any, will oxidize Fe(s) while leaving Cu(s) unreacted? If none of the available reagents can be used for this purpose, then identify another reagent from the table that could be used. For each reagent you've i..
What is the half-life of a compound if 63 percent of a given sample of the compound decomposes in 72 min? Assume first-order kinetics.
At a certain temperature the equilbrium constant is 396 K for H2(g) + I2(g) ↔ 2HI(g) , Calculate the the equilbrium constant for 0.5H2(g) + 0.5I2(g) ↔ HI(g)
Eugenol can also be isolated from cloves using extraction with CO2. discuss the advantages and disadvantages of distillation versus CO2 extraction.

CH3SH, has a substantial dipole mement (1.52) even though carbon and sulfer have identical electronegativities.
The rate at which a metal alloy oxidizes in an oxygen containing atmoshphere is a type of the Arrhenius equation (rate(k)=Ce^(-Q/RT)). For example, the rate og oxidation of a magnesium alloy is represented by a rate constant k.
