How much energy will be needed to heat 45.7 gal of water from 22.0 oC to 110.0 oC? (Note that temperature 110.0 oC can be at a certain pressure greater than 1 atm. Note that 1.00 gal weighs 3.77 kg and that water has a specific heat capacity of 4.184 J/goC.)
which is the desired product, can decompose to product F, how might you ensure that you stopped the reaction at the optimum point to ensure the maximum yield of C?
She then took 15.0 mL of the stock solution and diluted it with enough water to make 65.0 mL of a final solution. What is the concentration of KOH for the final solution.
Liquid sodium is being considered as an engine coolant. How many grams of liquid sodium (minimum) are needed to absorb 9.30 MJ of energy (in the form of heat) if the temperature of the sodium
starting with ethyne and any alkyl halide with four or fewer carbons, any needed inorganic reagents, show how you would synthesize the following compounds
A compound contains only carbon, hydrogen, and oxygen. Combustion of 138.7 g of the compound yields 203.3 g of CO2 and 83.23 g of H2O.
Determine the mass of sodium phosphate that yields 1.00 g of calcium phosphate precipitate.
is it possible to synthesize 1-bromo-4-nitrobenzene by reacting bromobenzene with a mixture of nitric and sulfuric acids. However, 1-bromo-4-nitrobenzene is not obtained if nitrobenzene is reacted with Br2/FeBr3. Explain the difference
A researcher studying the nutritional value of a new candy places a 4.40-gram sample of the candy inside a bomb calorimeter and combusts it in excess oxygen. The observed temperature increase is 2.86 °C.
a large flask with a volume of 936 ml is evacuated and found to have a mass of 134.66g. it is then filled to a pressure
An unknown metal with a mass of 100 g was heated to 100 C and placed into 30.0 g of water that had a temperature of 20.2 C. The final temperature of both substances
