A house is designed to have passive solar energy features. Brickwork incorporated into the interior of the house acts as a heat absorber. Each brick weighs approximately 1.8 kg. The specific heat of the brick is 0.85 J/g-K. How many bricks must be incorporated into the interior of the house to provide the same total heat capacity as 1.1 103 gal of water?
compound noradrenaline contains 56.79% C, 6.56% H, 28.37% O, and 8.28% N by mass. What is the empirical formula for noradrenaline?
CH3SH, has a substantial dipole mement (1.52) even though carbon and sulfer have identical electronegativities.
A 45- piece of ice at 0 is added to a sample of water at 20. All of the ice melts and the temperature of the water decreases to 0. How many grams of water were in the sample
A voltaic cell is constructed by immersing a strip of silver metal in a 1.0M AgNO3 solution and a strip of Cadmium metal in a 1.0M Cd(NO)3 solutio. the circuit is completed by a wire and a salt bridge in the usual way.
how would you make a 50.0 mm mops buffer pka7.15 at ph7.00 using a 500 mm sol of mops acid and a 1.00 m sol of naoh?
draw an electron-dot structure for hydrogen peroxide. write balanced chemical equations for reactions of hydrogen
The solubility of AgCrO4 is several times greater than that of AgCl, so the red precipitate cannot form until all the chloride ions have effectively been removed from the solution.
Explain why the bond dissociation energy for the C-C sigma bond in propane is lower than the BDE for the C-C bond in propene.
calculate the heat transferred, Q when 51.0 ml of 2M NaOH solution and 50.0 ml of 2M HCl are mixed. Assume the final volume of the reaction mixture is 101.0 ml, its density is 104 g mL-1, and its heat capacity is 3.89 J g-1 deg-1
assume water upwelling to the surface the equation is ch230ch2o76nh317h3po4 nbsphas a total carbon concentration 2300
Hydrogen atoms that are bonded to an sp3 hybridized carbon atom normally appear between 0.9 & 1.8 ppm and are said to be shielded
