A special gas mixture used in bacterial growth chambers contains 1.00% by weight CO2 and 99.0% O2 . What is the partial pressure (in atmospheres) of each gas at a total pressure of 0.966atm?
Please note that NO3 has an odd number of electrons. But you must decide where the missing electron will be. Does the central atom violate the octet rule or do the oxygen atoms? Use formal charges to decide.

Calculate the pH during the titration of 50.00 ml of 0.0500 M NaOH with 0.1000 M CH3CO2H after the addition of the following volumes
If 5.68 g of Cu was added to 3.18 g of S8, How much copper (I) sulfide would be produced?
Suppose that 1.02 of rubbing alcohol evaporates from a 75.0 aluminum block. If the aluminum block is initially at 25C, what is the final temperature of the block after the evaporation of the alcohol?
The four molecular p orbitals of the four carbon atoms can be lined up parallel in order to create four new molecular orbitals. The electrons in the new molecular orbitals benefit because they are not confined to just one atom.
In combustion studies of the use of H2 as an alternative fuel, HO is sometimes formed in flames by the reaction, H(g) + 1/2 O2(g) HO(g) Use the data below to calculate the value of Kc H2(g) 2 H(g) Kc = 0.00473 1/2 H2(g) + 1/2 O2(g) OH Kc = 0..
