You start with 100.0 mL of a 0.2500 M solution of NaCl sitting in a beaker. After several days you test the solution and find that it is now 0.3125 M. How much water must have evaporated?
What is the Lewis structure of the covalent compound that contains one nitrogen atom, one hydrogen atom, and one carbon atom? Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.
How is concentration an intensive property? I mean if you add more amount of a substance(mass), the number of moles increase and so the concentration increases.
The equivalence point of the titration occurs at 23.74mL . Determine the molar mass of the unknown acid.
Heart pacemakers are often powered by lithium-silver chromate "button" batteries. The overall cell reaction is: 2 Li(s) + Ag2CrO4(s) ? Li2CrO4(s) + 2 Ag(s) The overall cell potential is 3.5V. What is the half-cell potential for the follow half rea..
The vapor pressure of a liquid is the pressure exerted by its vapor when the liquid and vapor states are in equilibrium. The relationship between vapor pressure and temperature is expressed by the Clausius-Clapeyron equation.
