Chromium(III) oxide (Cr203) reacts with silicon (Si) as indicated by the balanced equation below:
2Cr2O3(s) + 3Si(s) — 4Cr(s) + 3SiO2 (s)
Determine the mass of SiO2 (60.08 g mol-2) when 80.00 g of Cr2O3 (152.0 g mol-?) reacts with 30.00 g of Si.

Water is important for the of cells. a: size, shape, and temperature b: temperature, color, and odor c: color, odor, and size d: shape, temperature, and color

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!
