PLEASEEE PLEASEE HELP THIS IS MY FINAL EXAM AND I HAVE 30 MINS REMAINING You have 5 moles of O2. How many moles of CO2, are produced?

Ionic compounds are made of ions, and yet the overall charge of an ionic compound is neutral. why?

Which of the following is always a reactant in a combustion reaction? oxygen nitrogen hydrogen carbon

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!
