If 1.00 g of an unknown molecular compound contains 4.55 * 10 ^ 21 moleculeswhat is its molar mass?

The reaction q+r2=r2q is found to be first order in r2 and

Which statement is best described as a atom

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!
