Astudent adds 0.40g of sodium hydroxide to a clean, dry 250 ml beaker and leaves the beaker and leaves the beaker on the lab table. the mass of the empty beaker is 112.58g. after 24 hours, the student observes that the beaker contains a dry, solid white residue. the total mass of the beaker and its contents is 113.09g. following are three possible chemical reactions that could have occured: sodium hydroxide (solid) + carbon dioxide (gas) rightarrow sodium bicarbonate (solid) sodium hydroxide (solid) + carbon dioxide (gas) rightarrow sodium carbonate (solid) + water (gas) sodium oxide (solid) rightarrow sodium oxide (solid) + water (gas) use your knowledge of stoichiometry to determine which chemical reaction occurred. show your work, and explain your reasoning whenever needed.
