Let G be a connected graph which contains two spanning trees T1 and T2 that do not share any edges (note that G may contain edges that are in neither trees). Prove that G does not have a bridge. I have a hint for the answer: Show that each edge is in a cycle (2 cases). But I can't figure out the 2 cases. Some help please!

Write an assembly program which will read the value of the switches on the board, parse this number by looking at the 4 least-significant bits, using the lookup table from the prelab to get the value necessary to display this hex number on a 7-segment display, using shift instructions to adjust registers as necessary to parse the next set of values. Repeat until all four displays are accounted for. Finally, when one register has a bit-stream necessary to display all...

Carbon disulfide and chlorine react according to the following equation: CS2(g) + 3Cl2(g) S2Cl2(g) + CCl4(g) When 2.94 mol of CS2 and 5.60 mol of Cl2 are placed in a 2.00-L container and allowed to come to equilibrium, the mixture is found to contain 0.580 mol of CCl4. How many moles of Cl2 are present at equilibrium?

In the gas phase, N2O5 decomposes according to the following reaction 2N2O5 (g) --> 4NO2 (g) + O2 (g) We put some N2O5 (g) in a container and it has a pressure of 0.154 atm. After the reaction proceeds for 103 seconds, the total pressure has increased to 0.260 atm. Assuming constant temperature and volume, the average rate of disappearance of the N2O5 (g) during this time interval is answer is: 1.0 x 10^-3 atm/s Please show work :D
