When hydrochloric acid of 200 mL was mixed to a small piece of CaCO3 in the same calorimeter, the temperature increased by 4.25 degree celsius. determine the heat output for this reaction?
The formulas for ethane, ethene, and ethyne are C2H6, C2H4, and C2H2 respectively. Rank these compounds by the length of the carbon-carbon bond. Longest C-C Bond to Shortest C-C bond
The "Zebra" cell was invented in 1985 in South Africa as part of the "ZEolite Battery Research Africa" project, and is used in all-electric municipal buses and other vehicles.
A certain mass of oxygen was collected over water when potassium chlorate was decomposed by heating. The volume of the oxygen sample collected was 870 mL at 40C and a barometric pressure of 755 torr.
If 42.0 g of CO and 27.0 g of H2O are placed in a 5.0 L flask with 132 g of CO2 and 6.0 g of H2 and allowed to reach quilibrium, what will the concentration of CO be when the system finally reaches equilibrium?
what is the theoretical yield of zinc iodide, if a 2.0-g sample of zinc was used with 6.5 grams of iodine
Extracting aluminium uses a current of 25000 ampere.What is the time taken to produce 10kg of aluminium from Al2O3(liquid
Hydrogen gas (H2) and oxygen gas (O2) are the products when an aqueous acidic solution is electrolyzed; each mol of water gives one mol of H2 and half a mol of O2.
The standard enthalpy of formation of gaseous H2O at 298 K is -241.82 kJ mol-1. Estimate its value at 75 °C given the following values of the molar heat capacities at constant pressure:
Calculate (a) the kilograms of water per minute needed to remove the sulfur dioxide assuming that the exit water is in equilibrium with the entering gas and (b) the ratio of the water stream to the gas stream. The Henry's law constant for sulfur d..
