Ethane is burned with 20% excess air in a furnace operating at a pressure of 100 kPa. Assume complete combustion occurs. Determine the dew point temperature of the flue gas.
Cinsider the reaction 2KCl3(s) --> @Kcl(s) + 3O2(g) How many grams of oxygen are produced from the complete reaction of 23.8g of KCL3? How many molecules are present in 1.80g of C6H8O6
how many moles are present of an ideal gas at the following conditions: 1.0 atm, 25.0 C, and occupying 22.4 L, The Lewis structure for PF3 shows that the central phosphorus atom has _______ nonbonding and
A bunsen burner uses the combustion of butane (c_4_H_10_) as a means to provide heat. If during a laboratory experiment the class uses 875 grams of butane. how many grams of each product will be produced?
Determine the number of bonding electrons and the number of nonbonding electrons in the structure of XeF2
Explain how the carbonate system in natural waters provides buffering capacity
the sodium acetate play in the synthesis of the amide functional group of phenacetin?
calculate the change in ph when 6 ml of 0.1 M HCl is added to 100 ml of a buffer solution that is 0.1 M in NH3 and 0.1 M in NH4Cl. And calculate the change in PH
How many grams of dry NH_4Cl need to be added to 1.60 L of a 0.800 M solution of ammonia, NH3, to prepare a buffer solution that has a pH of 8.99? Kb for ammonia is 1.8*10^{-5}.
if you take a 12.5 mL portion of the stock solution and dilute it to a total volume of 0.600L what will be the concentration of the final solution?
Phosphorus pentachloride is used in the industrial preparation of organic phosphorus compounds. Equation 1 shows its preparation from PCl3 and Cl2.
High temperature and low pressure low temperature and high pressure none of the above unless a catalyst is present If it's endothermic, it's high temp and low pressure, but does having an exothermic reaction change that?
A 1.50 g sample of solid NH4NO3 was added to 35.0 mL of water in a styrofoam cup (insulated from the environment) and stirred until it dissolved. The temperature of the solution dropped form 22.7 C to 19.4 C. What is the heat of reaction for disso..
