Problem- The main cables supporting New York's George Washington Bridge have a mass per unit length of 4100 kg/m and are under tension of 250 MN. At what speed would a transverse wave propagate on these cables?
If possible just a brief explanation how you got the answer?
State a Lewis structure that obeys the octet rule for each of the following ions. Allocate formal charges to each atom.
A sample of oxygen gas is collected over water at 25 degree Celsius and a total pressure of 654 torr. The volume of the gas collected is 500 ml. What mass of oxygen is collected. The vapor pressure of water at 25 degree celsius is 23.8 torr
The "roasting" of 48.7 g of ZnS at constant pressure gives off 220. kJ of heat. Calculate the DH for this reaction. 2ZnS(s) + 3O2(g) ® 2ZnO(s) + 2SO2(g)
When the metal was placed in a constant-pressure calorimeter containing 30.0g of water, the temperature of the water rose from 24.80 degrees C to 29.75 degrees C. Calculate the specific heat of the metal.
Explain what is the molarity of a solution containing 5.035 grams of FeCl 3 in enough water to make 500mL of solution
Give the structure that corresponds to the following molecular formula and 1H NMR spectrum: C7H12Cl2: ? 1.07 (integral = 6203, s); ? 2.28 (integral = 1402, d, J = 6 Hz); ? 5.77 (integral = 700, t, J = 6 Hz).
A constant current of 5.00mA is allowed to flow through an electrochemical cell for 528 seconds as Ag+ is reduced to silver metal from 100.0mL of an aqueous sample.
after swimming in a pool or lake the air feels cool because heat is required to evaporate the water from our skin. how
Which one corresponds to conditions of constant volume? Explain.
Draw a complete lewis structure that shows all bonds, unshared electron pairs, and minimized formal charges where appropriate.
Calculate the pH of a solution prepared by adding 20.0 mL of 0.100 M HCl to 80.0 mL of a buffer that is comprised of 0.25 M C2H5NH2 and 0.25 M C2H5NH3Cl. Kb of C2H5NH2 = 9.5 x 10-4
50.50 mL of 0.116 M HF is titrated with 0.1200 M NaOH. How many mL of the base are required to reach the equivalence point? (Ka for HF is 6.8 x 10-4)
