A mixture of CS2 (g) and excess O2 (g) is contained in a 10.0-liter reaction vessel at 100.0°C; the total pressure of the mixture is 3.00 atm. A spark causes the CS2 to ignite, and it burns completely according to the following equation: CS2(g) + 3O2(g)?CO2(g) + 2SO2(g)
The vessel and contents are returned to 100°C and the mixture of product gases (CO2, SO2, and unreacted O2) has a total pressure of 2.40 atm. Determine the partial pressure of each of these gases in the final product mixture.
Table salt contains 39.99g of sodium per 100 g of salt. The US FDA recommends that adults consume less than 2.40 g of sodium per day. A particular snack mix contains 1.20 g of salt per 100g of the mix. What mass of the snack can you consume and st..
the reactants in a Diels-Alder reaction are used in a 1:1 ratio. In this experiment, one reagent is used in excess. Which reagent is in excess, and why is it important that so much of it be used?
a mixture of three gases has a total of 756 mm Hg. If the pressure of nitrogen is 612 mm Hg and the pressure oxygen if 100 mm Hg, what is the pressure of the carbon dioxide gas in the mixture?
A 15.0 L sample of a gas has a mass of 18.0 g at 25.0 ° C and 740. torr. What is the density of the gas at STP?
If the average kinetic energy of a gas is doubled and the volume remains constant, what is the change in pressure
0.400 M hydroxylamine (HONH2) and 0.15 M sodium hydroxide, are titrated by 0.100 M HCL (the titrant). For each volume of titrant calculate the pH. volumes (all in mL) include 0, 30.00, 60.00, 120.0, 180.0
In a certain chemical reaction, 7.29g of compound A is added to 5.70 g compound of B. Once the reaction is complete, 3.60 g of compound A and 1.17g of compound B remain. What is the mass of products was produced
Furoic acid, HC5H3O3, has a Ka value of 6.76 10-4 at 25C. Calculate the pH at 25C for a solution formed by mixing 28.0 mL of 0.260 M HC5H3O3 and 23.0 mL of 0.21 M NaC5H3O3 and diluting the total volume to 125 mL.
Explain the valences for each, showing what may happen to the electronic structure in each case
