When doing the kinetic trials, someone mistakenly omitted the Sodium Thiosulfate solution. How will this omission change the appearance of the resultant and why?
Sulfur dioxide gas is oxidized in 50 percent excess air with 70 percent conversion to sulfur trioxide. The gases enter the reactor at 350 oC and leave at 450 oC.
How much heat is evolved in converting 1.00 mol of steam at 130.0 C to ice at -50.0 C? The heat capacity of steam is 2.01 J/g*C and of ice is 2.09 J/g*C.
How many grams of H2O (g) are theoretically produced from 1026.9 g of sucrose, C12H22O11 (g), and an excess amount of oxygen? C12H22O11 (g) + O2 (g) → CO2 (g) + H2O (g) (unbalanced)
A 48.1 mL sample of gas in a cylinder equipped with a piston is warmed from 22 degrees C to 90 degrees C. what is the volume at final temperature?
what is the molar concentraion of the salt solution formed n this reaction? B. what is the molar concentraion of the excess reactant once this reaction has finished?
Calcium fluoride, CaF2, is a source of fluorine and is used to fluoridate drinking water. Calculate its molar mass to four significant figures.
Calculate the standard emf for each of the following reactions:a)H2(g) + F2(g)---> 2H+(aq) + 2F-(aq)
Calculate the amount of these reactants required to produce 14 grams of 5-methyl-5-nonanol assuming an 80% yield.
A 75.0 L steel tank at 20.0C contains acetylene gas (C2H2) at a pressure of 1.39 atm. Assuming ideal gas behavior, how many grams of acetylene are in the tank?
Concrete used in road construction is reinforced using steel bars in a grid, known collectively as "rebar." After many years, rebar will begin to corrode, and the concrete will weaken.
A 86 gram solution of silver nitrate contains 14 grams of AgNO3. What is the percent by mass of silver nitrate in this solution.
In a particular redox reaction, Cr is oxidized to CrO42 and Ag is reduced to Ag. Complete and balance the equation for this reaction in acidic solution. Phases are optional.
