You prepare an NaOH solution with a concentration of approximately 0.200 M. In order to standardize the solution, you will need to titrate it against an acid standard. What mass of sulfamic acid (H2NSO3H) will you need to use in order that the titration will require 40.00 mL of the NaOH solution?
what is the theoretical yield of vanadium that can be produced by the reaction of 40.0 g of v2o5 with 40.0 g of calcium
Imagine you are driving at speed 60 mph through air filled with bugs at concentration 1 per cubic meter. The windshield is a flat panel of area 2 m^2 tilted so that it is at 60 degrees with the ground. How many bugs will you collect in 5 min?
Calculate the work done (in joules) if the gas expands against a constant pressure of 2.1atm. Enter your answer in scientific notation.
A particular coal contains 2.92% sulfur by mass. When this coal is burned, the sulfur is converted into sulfur dioxide gas. The sulfur dioxide gas then reacts with calcium oxide to form solid calcium sulfite
