How many electrons make up one coulomb of charge? (Hint: q = ne.) An object has one million more electrons than protons. What is the net charge of the object?
Sodium hydroxide (NaOH) has a lattice energy of -887 kJ/mol and a heat of hydration of -932 kJ/mol.
flask apparatus which now contains 2.00 l h2 at a pressure of 360 torr and 1.00 l n2 at an unknown pressure. if the
While 0.56 g of Na(s) reacts with excess F2(g) to form NaF(s), 13.8 kJ of heat is evolved at standard-state conditions. Define what is the standard enthalpy of formation (H) of NaF(s)
When the two cylinders are connected and the gases mixed, the pressure in each cylinder becomes 8.71 atm. What is the volume of cylinder B?
You are asked to determine the strength of an acid by titration with NaOH. Exactly 50.0 ml of the acid are titrated with 0.300M NaOH and the equivalence point is reached at exactly 20.0 ml of NaOH. What is the molar strength of the acid
Why did the book suggest using a Hirsch funnel? What would be the benefit of using a Hirsch funnel?
The payment sugar beet growers receive is based on the sucrose content of their delivered beets. A sample is taken from each load of beets and the sugar content in the beets is determined by polarimetry of the beet extract. In a typical situation ..
a 5.08-g chunk of potassium is dropped into 1.06 kg water at 24.0degc. what is the final temperature of the water after
A 750-mL sample of hydrogen exerts a pressure of 822 torr at 325 K. What pressure does it exert if the temperature is raised to 475 K at constant volume
Ethylene is supplied by a 60.9-L gas cylinder initially at 2200.0 psig and 25.0°C. Once leaving the cylinder, a regulator reduces the pressure to 15.0 psig, and a valve allows 1.000 mL/s of ethylene at 25.0°C to flow into the reactor
a cylinder measuring 3.4 cm wide and 4.0 cm high is filled with gas. The piston is pushed down with a steady force measured to be 275 kpa
A balloon contains 2.3 liters of nitrogen gas at a temperature of 77 K and a pressure of 101 kPa. If the temperature of the gas is allowable to increase to 39°C and the pressure remains constant, what volume will the gas occupy
