An automobile engine provides 539 Joules of work to push the pistons and generates 2120 Joules of heat that must be carried away by the cooling system.
Calculate the change in the internal energy of the engine.
Complete combustion of a 0.360g sample of glucose produced 0.528g carbon dioxide and 0.216g of water. Find the empirical formula for glucose.
determine the numerical values for them the subscript hot, cold, and total stands for the hot brick, the cold brick and the sum of the two.
the vapor pressure of n-heptane (n-C7H16) is 92mm use raoults law to calculate the vapor pressure at 40 degree C of a 3:1 molar mixture of n-pentane and n-heptane do the same for a mixture containing 50 g of each component.
Question- Show that the total energy eigenfunctions Psi210(r, theta, phi) and Psi211(r, theta, phi) are orthogonal. Do you have to integrate over all three variables to show that the functions are orthogonal?
Suppose that the microwave radiation has a wavelength of 12.4cm . How many photons are required to heat 295mL of coffee from 25.0 C to 62.0 C ? Assume that the coffee has the same density, 0.997 g/mL , and specific heat capacity, 4.184 J(gxK) , as..
There are about 1,200,000 autos .each auto emits 3.1g NO2 and 1.6g CH4 per vehicle mile. Each auto travels 30 miles round trip per day. How much NO2 and CH4 in g/day is emmited in the air daily?
A 25.0-mL sample of a 0.090 M solution of aqueous trimethylamine is titrated with a 0.11 M solution of HCl. Calculate the pH of the solution after 10.0, 20.0, and 30.0 mL of acid have been added; pKb of (CH3)3N = 4.19 at 25*C
