A wire is made out of aluminum with a cross-sectional area of 5.75×10-4 m2 and a length of 55 km. Assume the resistivity of aluminum is 2.65×10-8Ω⋅m.
What is its resistance?
Rewrite the atomic cores in the space below. Place an electron pair between each hydrogen atom and the sulfur atom. Write the lewis structure for hydrogen sulfide in the box, distirbuting the remaining valence electrons so that the hydrogen atoms ar..
Consider the titration of 50.0 mL of 0.217 M HN3 (Ka = 2.6 x 10-5) with 0.183 M NaOH. Calculate the pH of the solution after the addition of 29.6 mL of NaOH solution.
This experiment calls for the use of 2mL of 2-chloro-2methylpropane. The molar mass of 2-chloro-2methylpropane is 92.57g mol-1, and its density is 0.847g mL-1. 1) Calculate the number of moles of 2-chloro-2methylpropane used in this experiment.
One series of lines of the hydrogen spectrum is caused by emission of energy accompanying the fall of an electron from outer shell to the fourth shell. The lines can be calculated using the Balmer-Rydberg equation
Four moles of N2 Nitrogen grams at 500K and 2.00 bar undergo a reversible adiabatic compression to a final temperature of 1000K. Calculate w,q,?U and ?H for the process, assuming that N2 gram is ideal with Cp=30.5JK^-1mol^-1
a calorimeter containing 200.0 ml of water was calibrated by carrying out a reaction which released 15.6 kj of heat. if
