Problem- For the straight line defined by the points (4, 57) and (6, 91), determine the slope and y-intercept. Do not round the answers.
It is not a question in the book, so I just need the full solution of deriving!
Question- The faraday is equal to 96,845 coulombs. A coulomb is the amount of electricity passed when a current of one ampere flows for one second. Given the charge on an electron, 1.6022 x 10^ -19 coulombs, calculate a value for Avogadro's number
Define what values of J may occur in the terms (a) 1S, (b) 2P, and (c) 3P? Explain how many states distinguished by the quantum number Mj belong to each level

If 2.00 moles of acetylene react completely with sufficient oxygen, how many grams of carbon dioxide are produced?
Imagine that 1.00 mol H2O(l) is placed in a piston with a constant external pressure Pext = 1 bar. The piston is then placed in a large thermal bath at a temperature of 270 K.
After the resulting reaction was complete, back titration required 10.40 mL of 0.1212 M NaOH. Assuming that the tablet contained only calcium carbonate and an inert binder calculate the mass of calcium carbonate and mass percent of calcium carbona..
a.)100 mL of 1.00 M HCl solution is titrated with 1.00 M NaOH solution. You added the following quantities of 1.00 M NaOH to the reaction flask. Classify the following conditions based on whether they are before the equivalence point
