Suppose an ice cube weighing 44.7 g at a temperature of -4 degree celcius is placed in 550 grams of water at a temperature of 23 degrees celcius.
25.00 mL of 0.25 M formic acid is titrated with 25.00 mL of .2500 M NaOh. What is the pH at the equivalence point?
Gold can be hammered into extremely thin sheets called gold leaf. If a 202-mg piece of gold (density = 19.32 g/cm3) is hammered into a sheet measuring 2.4 ft multiplied by 1.0 ft, what is the average thickness of the sheet in meters?
What is the boiling point of a solution that contains 6 moles of KBr in 1000 g of water? (K = 0.512 C/m)
In an experiment 1.65g of lead(ii) nitrate react with .327g of zinc. What is the mole relationship between the lead nitrate and the zinc.
Silver chloride, often used in silver plating, contains 75.27% Ag.Calculate the mass of silver chloride in grams required to make 4.4 grams of silver plating.
How much water must be added to 534. mL of 0.180 M HCl to produce a 0.135 M solution? (Assume that the volumes are additive.)
Calculate how many grams of ATP must be produced to walk a mile. ATP synthesis is coupled to the oxidation of glucose (?Go' = -686 kcal/mol). How many grams of glucose are actually metabolized to produce this amount of ATP?
Ethanethiol (C2H6S) is a compound with a disagreeable odor that can be used to impart an odor to natural gas. When ethanethiol is burned, the sulfur reacts with oxygen to form SO2
