Calculate the molarity of a solution made by dissolving 0.140 mol Na2SO4 in enough water to form exactly 800mL of solution.
Fusion of boric acid with sodium oxide forms a borate salt, Na2BO7. Without writing complete equations, find the mass (in grams) of B5H9 required to form 156g of the borate salt by this reaction sequence.
If 10.00 mL of 0.050M KI solution is mixed with 40.00 mL of other reagents what would be diluted concentration of KI
Crystalline silicon has a cubic structure. The unit cell edge length is 543pm. The density of the solid is 2.33g/cm3. Calculate the number of Si atoms in one unit cell.
When combining atomic orbitals to form hybrid orbitals, how many hybrid orbitals are formed
Consider the following reaction: CO(g)+2H2(g)-->CH3OH(g) Kp=2.26x10^4 Calculate deltaGrxn for the reaction at 25 C at equilibrium and when: PCh3OH = 1.1 atm, PCO = PH2 = 1.3*10^-2 atm. I got the correct original deltaG, it's -24.8 KJ
