A compound contains 43.64% P with the remainder being oxygen. What is the empirical formula of the compound?
the change in the revenue that arises when one additional unit of a product is sold. The marginal revenue is calculated by dividing the change in the total revenue by the change in the quantity. In calculus terms, the marginal revenue is the first derivative of the total revenue function with respect
For example, the total cost of producing 100 units of a good is $200. The total cost of producing 101 units is $204. The average cost of producing 100 units is $2, or $200/100; however, the marginal cost for producing the 101st unit is $4, or ($204 – $200)/(101-100). The marginal revenue measures th
If the total translational kinetic energy of the molecules of oxygen in a container is 15 J at room temperature, what is the total rotational kinetic energy of these molecules?
Describe how the chemical characteristics, production methods, uses, and associated unique hazards of sulfur can affect the safety of an environmental health and safety (EHS) and fire science (FS) professional.
A 295mLflask contains pure helium at a pressure of 742torr . A second flask with a volume of 465mL contains pure argon at a pressure of 717torr .If the two flasks are connected through a stopcock and the stopcock is opened, what is the partial pressure of helium?
what is the H+ for a solution with a pH = 5.66? OH-? pOH?
The distances from the Sun at perihelion and aphelion forMars are 2050·105 km and 2490·105 km, respectively. What isthe ratio of Mars’ orbital speed around the Sun at perihelionto that at aphelion?
(z)-1,3,5-tribromo-2-pentenehow does the structure look?
A professor’s office door is 0.95 wide, 2.2 high, 4.0 thick; has a mass of 22 , and pivots on frictionless hinges. A “door closer” is attached to door and the top of the door frame. When the door is open and at rest, the door closer exerts a torque of 5.8 .
