What is the concentration of [Cl?] in a solution of 10 mL of 12 M HCl when 6 mL of water is added
1 calorie = heat required to raise temp. Of 1.00 g of H2O by 1.0 oC. Which has the larger heat capacity? How much energy is transferred due to T difference?
Under these conditions, calculate the final concentration of glycerol-3-phosphate. Remember to convert kJ to J.
which is connected to 2 oxygen atoms, one with is sp^3 and one sp^2 hybridized and so both oxygens have 2 lone pairs of electrons. All other single bonds consist of hydrogen.
For the reaction PCl5-> PCl3+Cl2 kp= 26.03 at 800K. calculate the equilibrium partial pressure for the reactant and product if the initial pressures are PPCl5= .54 atm and PPCl3= .37 atm.
When a sample of aqueous hydrochloric acid was neutralized with aqueous sodium hydroxide in a calorimeter, the temperature of 100.0 g of water surrounding the reaction increased from 25.0°C to 31.5°C.
calculate delta G foor the combustion of ethane: 2C2H6(g) + 7O2(g) = 4CO2(g) + 6H2O(l)
A (identical to the starting ester) and E. Propose a neutral structure for each compound that is consistent with the data. Note that the absolute stereochemical configurations of chiral substances cannot be determined from the data. Arbitrarily dr..
List and describe at least three prokaryotic cellular features that could be targeted in this way to inhibit or kill a bacterial pathogen.
The speed of a photon is 4.5x10^5 ms^-1. If the uncertainty in its momentum is to be reduced to .01 percent, what uncertainty in its location must be tolerated
