A person inhales air richer in O2 and exhales air richer in CO2 and water vapor. During each hour of sleep, a person exhales a total of 300. L of this CO2-enriched and H2O-enriched air.
(a) If the partial pressures of CO2 and H2O in exhaled air are each 29.5 torr at 35.6°C, calculate the masses of CO2 and of H2O exhaled in 1.00 hour of sleep.CO2
H2O
(b) How many grams of body mass does the person lose in about 8 h sleep if all the CO2 and H2O exhaled come from the metabolism of glucose? C6H12O6(s) + 6 O2(g) 6 CO2(g) + 6 H2O(g)
A student heated 1.0L of ethanol (density 0.789 g/L) with 1.0 mL ethanoic acid (density 1.049 g/mL) with a sulfiric acid catalyst and noticed a vinegar-like smell to the product as well as a fruity medicinal smell.
A certain mass of oxygen was collected over water when potassium chlorate was decomposed by heating. The volume of the oxygen sample collected was 870 mL at 40C and a barometric pressure of 755 torr.
What is the pH of a solution prepared by adding 66.0 ml of 0.100 M HCl to 43.0 ml of 0.200 M NaOH
Hydrogen fluoride is a highly reactive gas. It has many industrial uses, but the most familiar property of HF is its ability to react with glass. As a result, HF is used to etch glass and frost the inner surfaces of light bulbs.
A buret containing NaOH solution has an initial reading of 0.14ml. 25.00ml of 0.1000M HCl is titrated to a phenolphthalein end point,
carbonic acid solution with [H_2CO_3] = 0.00735 M is titrated with 0.100 M KOH. Determine the pH of the solution when 70.00mL of OH have been added.
A 0.1752g sample of silver nitrate was dissolved in 502.3g of distilled water. Calculate the weight molarity of silver in this solution.
Acid halides and Acid anhydrides can also be used to make esters - show how ethyl ethanoate can be made from a) and acid halide and b) an acid anhydride
Draw the Newman projections for the anti and gauche forms of 1,2-dibromoethane. The molecule has a dipole moment of 1.0 D.
The maximum temperature attainable in the crucible on strong heating with a Bunsen burner is approximately 800°C. Can the magnesium evaporate under the conditions of this experiment? Why or why not?
At a certain temperature, a saturated solution contains 537 g of NaOH(s) per liter of solution. Calculate the molarity of this saturated NaOH(aq) solution.
An unknown metal is found to have a density of 19.300g/cm^3 and to crystallize in a body-centered cubic lattice. The edge of the unit cell is found to be 0.28864nm. Calculate the atomic mass of the metal
