Two metal objects were found. One has a mass of 35 g and a volume of 5.5 mL and the other has a mass of 52 g with a volume of 6.1 mL. Comment on whether these are made of the same materials or not, and explain your response. The density is different in each, so they are made of different materials.
ond weighs 44.0 carats. Determine the volume occupied by the diamond, given that its density is 3.5 g/cm3 at 20°C, and that 1 carat = 0.200 g.
We do not have a reliable method for determining the number of molar equivalents of bleach being added because commercial preparations vary in concentration and "oxidizing power
Calculate the [Zn2+] in a solution of ZnC2O4 held at a pH of 3.00. Remember C2O4^2- is a weak base so you must consider other equilibria. (Ksp(ZnC2O4)=7.5X10^-9, Kb1=1.8X10^-10, Kb2=1.8X10^-13).
A portable electric water heater transfers 255 watts (W) of power to 5.5 L of water, where 1 W = 1 J/s. How much time (in minutes) will it take to heat the 5.5 L of water from 24 degrees C to 41 degress C? (Assume that the water has a density of 1..
A chemistry student prepares acetone by decomposing 12.3 g of calcium acetate. If the student collected 2.50 g of acetone and the theoretical yield is 3.42 g.
The following series of reactions was done on a monosaccharide. Predict the structure of the monosaccharide based on the structure of the product
160 mL that contains 400 mg of NH3 and 980 mg of NH4NO3. (Given: Kb (NH3) = 1.8 x 10-5
calculate q, w, delta E, and delta H for the process in which 88.0g of nitrous oxide gas (N2O) is cooled from 165 degrees celsius to 55 degrees celsius at a constant pressure of 5.00 atm.
The product was then treated with toluene. Will the product result in the formation of 1-hexene, ethyl hexyl ether (1-ethoxyhexane), or both? Please explain.
Predict the products of the reaction between each of the following compounds and both chromic acid and PCC. a) 2-methyl-2-butanol
Label and identify ALL functional groups. Label the chiral carbons (*), label the priorities (1,2,3,4) of the four "things" connected to the chiral carbon, draw the arrow or rotation and identify as R or S.
An alcohol is 12.61 percent Hydrogen, 37.47 percent Carbon, and 49.92 percent Oxygen by mass. Determine the empirical formula of the alcohol.
