If 122 mL of a 1.2 M glucose solution is diluted to 550.0 mL, what is the molarity of the diluted solution?
How many mL of 2.00 M Na2CO3 is diluted with water to prepare 300 mL of 0.500 M Na2CO3
Consider the weak acid, with a Ka = (4.40x10^-4). In the titration of 25.00 mL of a 0.01000 M solution of the acid with 25.00 mL of a 0.01000 M solution of NaOH
The solubility of Ce(IO3)3 in a 0.20 M KIO3 is 4.4 multiplied by 10-8 mol/L. Calculate Ksp for Ce(IO3)3.
If 3.93 g of sodium borohydride contains 2.5 × 10e23 H atoms, how many moles of H are present in 33 cm3 of sodium borohydride (of density 1.074 g/cm3)?
a student mixes 5.0 ml 2.00 x 10-3 m feno33 with 5.0 ml 2.00 x l0-3 m kscn. she finds that in the equilibrium mixture
The initial DO of the mix is 9.0 mg/L. After 5 days, the DO is 4.0 mg/L. After a long period of time, the DO is 2.0 mg/L, and it no longer seems to be dropping. Assume nitrification has been inhibited so the only BOD being measured is carbonaceous..
vAt a particular temperature, K = 2.0 10-6 mol/L for the following reaction. 2 CO2(g) 2 CO(g) + O2(g) If 1.7 mol CO2 is initially placed into a 3.7-L vessel, calculate the equilibrium concentrations of all species. [CO2] [CO] [O2]
