Part A - Place the labels indicating oxidation numbers above each element in the unbalanced reaction: CrI3+ Cl2 → Cr042- +IO4 + Cl-

Write the complete balanced equation for the reaction between lead (iv) oxide (pbo2) and water (h2o).

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!
