hydrocarbon produced 24.8 g of CO2 and 8.44 g of H2O. What is the empirical formula for the hydrocarbon?
an iron piston in a compressor has a mass of 3.62 kg. if the specific heat of iron is 0.449 jgdegc how much heat is
When an ionic solid dissolves in water, water molecules attract the ions causing them to dissociate of come apart. The resulting dissolved ions are electrically charged particles that allow the solution to conduct electricity.
assume that the activation energy for a certain reaction is 173 kjmol and the reaction is started with equal initial
The human body is about 2/3 water. Sucrose is metabolized by the body. If the oxygen gas has a partial pressure of 162 Torr, what volume (at 37 degrees Celsius) is required for the metabolism reaction C_12_H_22_O_11 + O_2 > H_2_O + CO_2
HCL acid solution is standardized using 0.502g of sodium carbonate. Find the molarity of the acid if 30.5mL are required for the titration.
A sample of solid having a density of 4.88 g/cm3 had an apparent mass of 16.0886. The density of the balance weights is 8.00 g/cm3. Calculate the true mass of the object.
Molecules can be as small as a few atoms or as large as thousands of atoms. In 1962, Max F. Perutz and John C. Kendrew were awarded the Nobel Prize for their discovery of the structure of hemoglobin
