An isolated chamber with rigid walls is divided into two equal compartments, one containing gas and the other evacuated. The partition between the compartments ruptures. Subsequent to the passage of a sufficiently long period of time the temperature as well as pressure is found to be uniform throughout the chamber.
a) If the filled compartment initially contains an ideal gas of constant heat capacity at 1 MPa and 500 K, Define what the final temperature is and pressure in the chamber?
b) If the filled compartment initially contains steam at 1 MPa and 500 K, define what is the final temperature and pressure in the compartment?
What is the molarity of a solution prepared by diluting 25 drops of 0.35 M K2SO4 solution with 75 drops
The reaction is in acidic environment accoridng to MnO4(-)(aq) +As2O3 (s) = H3AsO4 (aq) +Mn(2+ )(aq) a. Balance in acidic B calculate the molarity of the KMnO4 solution.
If you dilute 750.00 mL of a 4.117 × 10-4 M solution into a 2.00 L volumetric flask and fill to the line with water, what would be the final concentration of the solution?
A healthy individual has a blood glucose concentration reported as 122 mg/dL. convert that to units of g/L
Although coals is a complex mixture of substances, its elemntal composition can be approximated by the formula C135H96O9NS. Using this formula predict the amount of CO2 released from the combustion of 1.00 x 10^6 metric tons of coal. 1 metric ton ..
A calorimeter with a heat capacity of 4.61 kJ/K contains 18,050 g of freon-12. Benzoic acid is combusted in the calorimeter and liberates 26,400 J of heat energy causing the temperature to rise 3°C. Calculate the specific heat of freon-12 in J/g°C..
Draw a Lewis dot structure for the fictitious molecular ion [ZO2]-2. Assume that the central Z atom is bonded to each of the outer O atoms by a single bond. What is the formal charge on the Z atom
Briefly explain why the part of the curve beyond the equivalence point is similar in the graphs for a strong acid-strong base and weak acid-strong base, even though you titrated a strong acid in one and a weak acid in the other.
One mole of He is heated from 200 degree C to 400 degree C at a constant presure of 1 atm . Given that absolute entropy of He at 200 degree C is 810 J/K/mole and assuming He is a perfect gas
Give an example of a ketone which will produce a positive iodoform test and another ketone w/ the same # of carbon atoms that will test negatively. Draw the structures.
Identify the longest, shortest, strongest and weakest bond out of the following: a triple bond, double bond, a single bond carbon attached to methyl groupCH3- CH2- CH- CH3 | CH3 and a single bond between a doubly bonded carbon attached to methyl g..
Calculate the equilibrium concentration of all the gases. This is the equation: 2NO(g)+2H2(g)=> N2(g)+2H2O(g). ( My instructor said that using the ICE table is a good method. if that helps in any way)
