1) If Congress taxes CO2 production at $40 per ton of CO2, what is the tax to burn one ton (2000 pounds) of coal which is 75% carbon? 2) How much heat energy can you get from burning that ton of coal? Take the book value ...
Predict whether a precipitation reaction will occur in the following situations. If a precipitation reaction occurs, enter the balanced chemical equation for the reaction. NiCl2(aq)+(NH4)2S(aq)→ AgNO3(aq)+CaBr2(aq)→
A hydrogen atom emits a photon as its electron changes from n = 5 to n = 2. For the H atom, E n = -2.18E-18*(1/n 2 ) J. What is the wavelength (in m) of the photon? ( ) m The number of significant digits is set to 3; t ...
Suppose a tank is filled with A2(g) so that initial pressure is 0.8688 atm at temperature of 298K. Some of the A2(g) dissociates and when the system reaches equlibrium the total pressure in the tank is 1.275 atm. Calcula ...
0.394 mol of a solid was dissolved in 340 mL of water at 26.9 oC. After the solid had fully dissolved, the final temperature of the solution was 31.6 oC. What is the molar heat of solution of the substance?
The density of air at STP is 1.29g/L. If your stoppered the250mL flask contains 242mL of water(also the volume of air it would contain), calculate the mass of air in the flask under STP.
