Consider the system A(g) --> B(g). a) Assuming that GoA = 8,996 J/mol and GoB = 11,718 J/mol, find the value of the equilibrium constant for the reaction. b) Calculate the equilibrium pressures for this system that will result if you first add 1.00 mol of gas A at a pressure of 1.00 atm and then mix in 1.00 mol of gas B, also at a pressure of 1.00 atm.

What is the chemical formula of the following compound

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
