Question- Part 1) Please explain the difference between Formula Units and Molar Mass
Part 2) Discuss what a "Kelvin" is and for what it is used.some details please
Part 3) Does a baseball have a deBroglie wavelength? If no, why not? If yes, why can't we see it?
Part 4) Using CO as an example, explain the differences in MO theory bonding and VSEPR theory bonding.
Please don't duplicate from internet and try to understand easily. I want to understand the answers. Thank you.
The final temperature of the uranium as well as deuterium mixture is 28.5 degrees Celsius. Specified the desities of the uranium (19.05) g/cm3) and heavy water (1.11 g/mL). Compute the edge length of the piece of cubic uranium.
When a 3.400 gram sample of an unknown alcohol is burned in oxygen, the products were carefully collected and weighed yielding 6.494 grams of CO2 and 3.985 grams of H2O. If the molecular weight of the unknown is 46.069 g/mol, what is the molecular ..
