Calculate the number of milliliters of 0.709 M KOH required to precipitate all of the Co2+ ions in 116 mL of 0.502 M Coso, solution as Co(OH)2. The equation for the reaction is:
CosO4(aq) + 2KOH(aq) —Co(OH)2(8) + K2SO4(aq)
mL KOH

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!

Significant figures are digits read directly from the measuring instrument plus one more digit, which is __ by the observer.
