How many particles are in the following samples A. 1.24 g cesium

B. 0.575 g cobalt(II) chloride

C. 65.6 g silicon dioxide

Which type of reaction always has an element and a compound as reactants

What is the overall order of reaction for rate = k[no]2[o2]

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!
