Starting out on a road trip you inflate your tires on your car to the recommended pressure of 46.5 psi on a day when the temperature is -5.0 C. Upon arrival at your destination, the temperature is now 28.0 C/ The volume of the tires has increased by 3.0%. The tire manufacturer warns that you not exceed the recommended pressure by more then 10%. Has the limit been exceeded? What is the final pressure in units of kpa and atm of tires
What is the molarity of a solution produced by dissolving 31 g of Cu(NO3)2 in a 100 mL volumetric flask?(Enter unit as M.)
The object ofthis problem is to determine V40, the required volume ofthe 40% mixture. Calculate V40 and do a degree-of-freedom analysis.
If 50.0 of ethanol (density 0.789g/mL) initially at 6.0 is mixed with 50.0 of water initially at 28.2 in an insulated beaker, and assuming that no heat is lost, what is the final temperature of the mixture?
What is the percent yield of a reaction in which 258 g phosphorus trichloride reacts with excess water to form 120. g HCl and aqueous phosphorous acid (H3PO3)
Carbon dioxide gas evolved out from the solution. After the reaction was completed. The solution was back titrated with a NaOH solution (3.05mL, 0.1500M). Write the reaction equation for the reaction of MCO3 and HCl
A solution containing 3.50 of sodium carbonate is mixed with one containing 5.00 of silver nitrate. How many grams of sodium carbonate are present after reaction?
Calculate the percent composition of copper in the hydrate CuSO4.5H2O based on atomic weight data.
Calculate the enthalpy change per mole for this process. ( Assuming C=4.18 J deg c^-1 g^-1 and density of the final solution is 1.00g/ml).
Assume that the coffee has the same density, 0.997 g/mL, and specific heat capacity, 4.184 \rm J/(g\K), as water over this temperature range. I got 1.64 x 10^20 photons for my answer, but i keep getting told that x 10 is not supposed to be in the ..
Question1 : If a sample of water from a pond is to be analyzed for whatever chemicals it may contain (including organic compounds and metal containing species), give a very brief, but specific description of the protocol that would be best used, i..
If 13.57 g of copper(II) chloride react, what is the maximum amount of precipitate that could be formed?
Cv and Cp denote the molar specific heat capacities of a gas at constant volume and constant pressure, respectively. Then (A) Cp âˆ' Cv is larger for a diatomic ideal gas than for a monoatomic ideal gas.
