Explain which element is the central atom, define how many bonds does the central atom form, is it polar or non-polar, define what the direction of negativity is
The reaction studied here converts ethanol to acetaldehyde, which is further converted to acetate that can be used to make other biomolecules easily utilized by cells. Imagine that methanol was used instead of ethanol - what is the reaction mechanism..
Problem- As a KBr and water solution begins to freeze, water molecules will tend to become organized into the pure ice crystal structure excluding the K+ and Br- ions which stay mixed with the remaining liquid water. Eventually, the remaining liqu..
a gas mixture contains 5.6 g of N2, 1.4g of h2, and 27.6 of CH4. What is the mole fraction of h2 in the mixture
Calculate the mole fraction of ethanol, C2H5OH, in a solution that contains 230. grams of C2H5OH and 312 grams of benzene, C6H6.
calculate the number of moles of the compound that could theoretically be generated. Use the value ?G°\'compound X = -62.3 kJ/mol. Round your answer to two significant figures.
A system undergoes a two-step process. In step 1 it expands adiabatically from 1.00 L to 2.56 L at 1.00atm external pressure. In step 2 it releases 73 J of heat at 1.00atm as it returns to the original internal energy. Determine the final volume o..
A sample containing 0.0250 M concentration of a dye in a cell of 1 cm^2 cross section has a measured absorbance of 1.012 at 650 nm.
At room temperature (20^circ rm C), milk turns sour in about 63 hours. In a refrigerator at 3^circ rm C, milk can be stored three times as long before it sours. Estimate the activation energy of the reaction that causes the milk to sour.
A thermometer indicates that water freezes at 0.5 degrees Celsius and boils at 100.2 degrees Celsius at a barometric pressure of 760 torr. The observed freezing point of an unknown liquid is -1.3 degrees Celsius.
A 2-kg mass of an ideal gas expands at a constant pressure of 172 kPa in a piston-cylinder system from a temperature of 32oC to a final temperature of 182oC. Determine Q, W, DeltaU and DeltaH.
