Eventually, the water cools to 25.0 degrees celsius while the temperature in the room remains unchanged. Calculate deltaS(sys), deltaS(surr), and deltaS(univ) for this process. You may assume that the density of water is constant over the temperature range and the heat capacity is constant at 74.5 J/K/mole
When burned in oxygen, 10.0 g of phosphorus generated enough heat to raise the temperature of 2950 g of water from 18.0oC to 38.0oC. The heat of formation of P4O10 from P4(s) and O2(g) is:
Find the Diffusivity of Ammonia gas(A) in a mixture of nitrogen(B) and hydrogen(C). D(AB)=3.28x10^(-5)m2/s and D(AC)=1.093x10^(-4)m2/s.
If the rate of appearance of oxygen (?[O2]/?t) is 6.0 x 10-5 M/s at a particular instant, what is the value of the rate of appearance of ozone (-?[O3]/?t) at this same time
What would be the product if dimethyl maleate (cis-MeCCH=CHCO2Me) was heated in the presence of 3-sulfolene?
What is the concentration of CO in molecules per cubic meter?
When 157mg of dipentylamine was added to 122mg of benzoic acid and 2mL of water, a completely homogenous solution was formed. Draw the sturctures of the species present in the water.
The half life of a first order reaction is 13 min. If the initial concentration of reactant is 0.085 M, what is its concentration after 8.2 minutes.
The value of Ka in water at 25 degrees Celcius for benzoic acid, C6H5COOH (aq), is 6.3 x10-5 M. Calculate the pH and the concentration of the other species in a 0.0200-M aqueous solution of C6H5COOH (aq).
In preparation of esters given in an experiment, the reaction product was extracted with 5% sodium bicarbonate solution (NaHCO3) in the isolation step. How? What gas was evolved during this washing step?
what is the molar heat of vaporization in kilojoules per mole if its vapor pressure at 20C is 540 torr?
Consider equal volumes (say 1 rm L) of a substance in the solid, liquid, and gas phases. Arrange them in order of decreasing mass. If the mass difference between samples is relatively small, rank the items as equivalent.
When the one ore lead (ii) sulfide burns in ixygen, the products are lead (ii) oxide and sulfur dioxide A. How many grams of oxygen are required to react with 0.126 mole lead (ii) sulfide?
