If 37.3 g of CO2 is produced in the reaction of C2H2 with O2 to form CO2 and H2O, how many grams of H2O are produced in this reaction?
Compute the pH of a solution made by mixing eighty grams of NaCH3COO, to 39 grams of CH3COOH, and adding in H2O to produce 500. mL of solution.
what will be the final temperature in degrees Celsius If the volume of a gas container at 32.0°C changes from 1550 mL to 755 mL,?
Some people think that driving a car, cooking on an outdoor grill, and using electricity produced by coal-fired generators contribute to global warming. What is the reasoning behind their thinking?
Calculate the enthalpy change for converting 10.00g of ice at -25.0°C to water at 70.0°C in kJ. The specific heats of ice, water, and steam are 2.09 J/g-K, 4.18 J/g-K, and 1.84 J/g-K,.
