A) Water (2330 g ) is heated until it just begins to boil. If the water absorbs 5.89×105 J of heat in the process, what was the initial temperature of the water?
Consider the following cell: Pt|H2(g, 0.645 atm)|H (aq, ? M)||Ag (aq, 1.00 M)|Ag(s) If the measured cell potential is 1.20 V at 25 °C and the standard reduction potential of the Ag /Ag half-reaction couple is 0.80 V, calculate the hydrogen ion con..
Boron shows anomalous behaviour in its groups because of its small size and non-availability of d orbitals. It resembles silicon, the second member of the next higher group.
Carbon monoxide (g) reacts with oxygen (g) to form carbon dioxide (g). In a 1.00 L flask, 2.40 atm of CO reacts with 4.50 atm of O2. Assuming that the temperature remains constant, what is the final pressure in the flask?
Describe an example of when you have used an acidic or basic solution in your home. Let's see how many different examples we can describe.
Individuals that ingested MPTP, produced during the attempted synthesis of MPPP an analog of prodine, developed symptoms indicative of Parkinson's Disease. Something went wrong with the synthesis. Describe the synthesis of MPPP, and explain what w..
A particular first-order reaction has a rate constant of 1.35x102 at 20 degrees C. Explain what is the magnitude of k at 75 degrees C if Ea =85.6Kj/mol
What is the compounds molar mass if the density of a gaseous compound of phosphorous is 0.943g/L at 474K when its pressure is 728 torr.?
Mitochondria are isolated from a cell and plunged into a solution containing a high concentration of radioactive protons (tritium). You remove the the mitochondria quickly so that each ATP synthase complex would only have enough time to make one m..
