Each step in the process below has a 70.0% yield. CH4 + 4Cl2 -> CCl4 + 4HCL CCl4 + 2HF -> CCl2F2 +2HCl The CCl4 formed in the first step is used as a reactant in the second step. If 7.00 mol of CH4 reacts, what is the total amount of HCl produced? Assume that Cl2 and HF are present in excess.
If 69.5 kJ of heat is applied to a 1039 g block of metal, the temperature of the metal increases by 11.4°C. Calculate the specific heat capacity of the metal in J/g°C.
An environmental chemist obtained a 200 mL sample of lake water believed to be cntaminated with a single monoprotic strong acid.
How much energy is released when 32.4 g of water freezes? The heat of fusion for water is 6.02 kJ/mol. q=? kJ
Determine How much Na2EDTA x 2 H2O must be weighed to form exactly two litres of 0.0500 M solution? FW=372.24
A 1.630 g sample of naphthalene, C10H8(s), is completely burned in a bomb calorimeter assembly and a temperature increase of 8.44°C is noted.
referring to the heating/cooling curve of a pure substance. Identify the line segment on the following diagram where the specific heat of the liquid is used to calculate energy flow
The pressure inside a hydrogen-filled container was 2.10 atm at 21 C. What would the pressure be if the container was heated to 94 C?
Assume that only a single stream exits the fuel cell. What is the flow rate of each of the species leaving the fuel cell? Not that the flow rates given to correspond a fuel cell rate at approximately 50kW using 2004 technology.
