A gaseous reaction takes place at a constant pressure of 50.0 atm and releases 64.0 kJ of heat. Prior to the reaction, the volume of the system was 6.60 L. Subsequent to the reaction, the volume of the system was 3.00 L. Compute the total internal energy change, Delta U, in kilojoules.
Bond length is the distance between the centers of two bonded atoms. On the potential energy curve, the bond length is the internuclear distance between the two atoms when the potential energy of the system reaches its lowest value.
Chemical Syntheis :At the end of the reaction you are to add ice. Which of the following are reasons for the adding ice. The melting ice dilutes the concentrated acids. The ice cools the reaction thus slowing it down to the point where it is effectiv..
A certain gas is present in a 13.0 L cylinder at 3.0 atm pressure. If the pressure is increased to 6.0 atm the volume of the gas decreases to 6.5 L. Find the two constants k1 , the initial value of k, and k1, the final value of k, to verify whethe..
For the system CaO(s) + CO2(g) = CaCO3(s), I added 1.00 mol of CaO(s) to 1.00L of 0.500M CO2(g) at 200 oC. At equilibrium the [CO2] = 0.150M. What is the value of Kp for this reaction?
Chemistry - Estimation of Mass Required in a Reaction, With the reaction, CaCO3+2Hcl->CaCl2+H2O+CO2. Using percent by mass what is the weight of HCl needed to react
Consider the reaction H2(g) + I2(g) -> 2HI(g) delta G degrees at 298K = 2.60 kJ/mol. In an experiment the initial pressures are H2=4.26 atm, I2 = 0.024atm, and the HI =0.23atm Calculate A. Dellta G and B. predict the direction of the net reaction
Could you please explain to me the purpose and what's happening when we add the MTBE and then the NaHCO3? I know it has to do something with getting rid of carboxylic acid? and then getting rid of water
A mixture of 0.0319 g hydrogen and 0.0178 mol oxygen in a closed container is sparked to initiate a reaction. How many grams of water can form?
A 25.0-mL sample of 0.150 M butanoic acid is titrated with a 0.150 M NaOH solution. What is the pH before any base is added? The Ka of butanoic acid is 1.5 x 10-5.
A lab procedure requires 35.0 mL of a liquid. Which of the following glassware should be used to obtain the volume with the greatest number of significant figures: 50mL beaker, 100mL erlenmeyer flask, 250mL graduated cylinder, 50mL graduated cylin..
