For each of the following 9 solutions, show the calculation for the mass of sucrose needed to make 50 grams of the given percent by mass solution of sucrose in water.
this is the prelab for unknown identification. The only formula given is percent by mass= (mass of solute/mass of solution)*100
Calculate the concentration of bicarbonate ion, HCO3-, in a 0.010 M H2CO3 solution that has the stepwise dissociation constants Ka1 = 4.3 × 10-7 and Ka2 = 5.6 × 10-11
A voltaic cell consist of an electrode composed of Sn(s) in a 1.0M Sn2+ ion solution as well as another electrode composed of Zn(s) in a 1.0 M Zn2+ ion solution, connected by a salt bridge. Compute the standard potential for the voltaic cell at 29..
A bar house with volume of 500 m^3, has 50 smokers in it. Each begins to smoke 2 cigarettes per hour at time t=0 hr. An individual cigarette emits about 1.4 mg of formaldehyde (HCHO).

Assuming the gasoline is pure octane (C8H18), how many liters of CO2 at STP will be produced from the combustion of 1.00 liter of gasoline. (assume the density of gasoline is 0.963 g/ mL).
Question- Given that Kw for water is 2.4× 10-14 at 37 °C, compute the pH of a neutral aqueous solution at 37 °C, which is the normal human body temperature.
Select all of the correct statements about equilibrium from the choices below. At equilibrium the rates of forward and reverse reactions are equal. As a reaction proceeds backwards toward equilibrium the reverse rate drops. At equilibrium all reac..
Nitric oxide, NO, is made from the oxidation of NH3, and the reaction is represented by the equation 4NH3 + 5O2 ï?® 4NO + 6H2O An 9.1-g sample of NH3 gives 12.0 g of NO. The percent yield of NO is.
Determine whether kinetic energy is being converted to potential energy, or vice versa, in the following process. a) Water cascades downward in a waterfall. b) Electrolysis of water produces H_2 and O_2.
A mixture of CO(g) and O2 (g) in a 1.0-L container at 1.0x10^3 Kelvin has a total pressure of 2.2 atm. After some time the total pressure falls to 1.9 atm as the result of formation of CO2. Find the mass (in grams) of CO2 that forms.
