We will deal with a 1.50 g sample of a diatomic gas initially in 1.20 L balloon at 30.7 in Hg and27 degreesC.
Charles's law. You put this balloon in your freezer where it is -3.0 degrees C. When you open the freezer in half an hour, what do you expect to see - what will happen to the balloon's volume?.
(a) The volume of this balloon will (increase/decrease) (slightly/dramatically). In this experiment (pressure/temperature/amount of gas) (is/are) constant
(b) Calculate the new volume using the ideal gas law.
Based on the structure and boiling point(176-177C) of Eucalytol. what aspects of this molecule allow it to separate from hexane? And which of the following temperature option of is best for separating eucalytus oil and why?
A 75.0 mL sample of acetic acid (HC2H3O2) is titrated to the equivalence point with 25.0 mL of 0.400 M NaOH. What is the molarity of the acetic acid solution?
Draw the skeletal structure of the given molecules given that each atom obeys the octet/duet rule and no atom possesses a formal charge, for the molecule whose condensed structure is (a) (CH3)2CHCHCHC(CH3)3
What is the molarity of a solution prepared by dissolving 10.5 grams of NaF in enough water to produce 750 mL of solution?
Lakes that have been acidified by acid rain can be neutralized by the addition of limestone (CaCO3). How much limestone in kilograms would be required to completely neutralize a 5.2 x 109 L lake containing 5.0 x 10-3 g of H2SO4 per liter
How much energy is necessary to heat 1.0 kg of water from room temperature (20°C) to its boiling point? (Assume no energy loss.)
How many milliliters of a 0.300 M lead(II) nitrate solution are needed to react with 50.00 mL of a 0.500 M potassium chromate solution?
IF the benzene ring has two halides i.e chlorine and bromine and we do dow process, which halide will it pick. The question looks something liike this
Calculate delta H of this reaction. Assume that the total volume is the sum of the individual volumes and the density and specific heat capacity of the solution are the same as for pure water. d for water=1.00g/mL; c for water=4.184 J/g degrees Ce..
Consider the following reaction at equilibrium. What effect will increasing the volume of the reaction mixture have on the system
Describe the predicted effect on glycine biosynthesis in a mutant mammalian cell if there is a mutation in the 5'-IRE sequence of ferritin mRNA that reduces the Ka of IRP binding as compared t binding with wild-type mRNA
