The Aerosol containers can be dangerous if they are heated because they can explode. Assume a container of hair spray with a pressure of 2040mm Hg at a T= 38*C id thrown into fire. Suppose T of the gas inside the aerosol can reach 520*C what will be its pressure?
Plot NO2 versus time, ln NO2 vs time, and 1/NO2 vs time. Which graph yields the best straight line? what is the reaction order with respect to NO2? Briefly explain
What is the percentage yield of SO3 if 22.3 g SO3 are obtained from the reaction of 25.0 g SO2 with an excess of O2.
if your body develops a charge of -20 (microcoulombs), how many excess electrons has it acquired?
Sulfur dioxide gas reacts with oxygen gas to form sulfur trioxide gas. What would the products of the reaction be
If an industrial diamond contained only carbon, how many atoms of carbon would be found in a 1.80-carat diamond
neutrons are used to obtain images of the hydrogen atoms inmolecules. what energy must be imparted to each neutron in
When aluminum crystalizes, it forms face-centered cubic cells. The atomic radius of an Al atom is 143. Caluculate the density of metallic aluminum.
The energy from condensing steam water is used to melt ice at 0 degrees Celsius. How much ice can be melted by condensing 1.0 kg of H2O vapor? (Delta H fus of ice= 6.01 kj/mol) (Delta H vap of water = 40.7 kj/mol)
Maleic acid is a carbon-hydrogen-oxygen compound used in dyeing and finishing fabrics and as a preservative of oils and fats. In a combustion analysis, a 1.054- sample of maleic acid yields 1.599 of and 0.327 of.
When a sample of H2S(g) (9.811 mol) is placed in 180.0 L reaction vessel at 724.0 K and allowed to come to equilibrium the mixture contains 0.01627 mol/L of S2(g). What is the equilibrium concentration (mol/L) of H2S(g)? 2H2S(g) = S2(g)+2H2(g)
A 45.3 g sample of Al at 95.5 oC is added to 182.7 g of water that is initially at 20.5 oC. The specific heat of Al and water are 0.90 J/(goC) and 4.184 J/(goC), respectively. Calculate the equilibrium temperature.
