Write the word, formula, and chemical equations for the reaction between hydrogen sulfide gas and oxygen gas that produces sulfur dioxide gas and water vapor.
In a chemical reaction (unbalanced equation), AsF3 + C2Cl6 -> AsCl3 + C2Cl2F4, the theoretical yield of C2Cl2F4 was calculated to be 1.86 mol. If the percent yield in the reaction was 77.2%,
At 25?°C, the vapor pressure of diethyl ether is higher than the vapor pressure of its isomer n-butanol, because A. diethyl ether has a higher density than n-butanol.
volume of 2.24 L at 288 K and 1.05 atm. Calculate the pressure when the volume is 1.19 L and the temperature is 303 K.
The CO 2 produced in one round of the citric acid cycle does not originate in the acetyl carbons that enter that round. Create a diagram of the TCA cycle to illustrate the answers to questions 1a and 1b.
2121g sample of an organic compound was burned in a stream of oxygen adn the CO2 produced was collected in a solution of barium hydroxide. Calculate the percentage of carbon in the sample if .6006 g of BaCO3 was formed
A gas has a volume of 10 L at 0 degrees C. What is the final temperature of the gas in C if its volume increases to 27 L? Assume that amount of the gas and its pressure remain unchanged.
what is the Na+ ion concentration in the solution by mixing 20 mL of .10 M Na2SO4 solution with 50 mL of .30 M Na3PO4?
How do the following changes affect the value of the equilibrium constant for a gas-phase exothermic reaction: 1. removal of a reactant
The glass electrode used in commercial pH meters gives an electrical response proportional to the concentration of hydrogen ion. To convert these responses to a pH reading
Write the balanced molecular equation, the total ionic equation, and the net ionic equation
When 5.00 g of fructose, C6H12O6, (FW 180.16 g/mol) is burned in a calorimeter whose heat capacity is 29.7 kJ/oK, the temperature increases by 2.635oK. Calculate the heat of combustion of fructose in kJ per mole.
Which solvent displayed the strongest propensity to encourage keto-enol tautomerization. CHCl3, DMSO, CH3OH? Or does this propensity more closely follow the type of solvent it falls under (such as nonpolar, polar aprotic, or polar protic).
