Barium reacts with water to produce barium hydroxide and hydrogen gas. When 5.489 g Ba is combined with 53.000 g H20, the reaction proceeds until all of the Ba is consumed. Ba(s) +2 H20(1) Ba(OH)2(aq) + H2 (g) The hydrogen gas escapes, and the final weight of the flask is 58.408 g. The remaining water is evaporated, leaving 6.849 g Ba(OH)2.

A sample of limestone and other soil materials was heated, and the limestone decomposed to give calcium oxide and carbon dioxide. CACO3 (s) → Ca0(s) + CO2 (g) A 5.483 g sample of limestone-containing material gave 2.14 g of CO2, in addition to CaO, after being heated at a high temperature. What was the mass percent of CACO3 in the original sample? %

Write the balanced molecular chemical equation for the reaction in aqueous solution for sodium hydroxide and tin(IV) acetate. If no reaction occurs, simply write only NR. 1 2 3 4 O 口。 ロ Dロロ:ロ|0口。 (s) (g) (aq) H. NR Na Ti Ac Sn

Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation. Be sure the equation you submit is balanced. (You can edit both sides of the equation to balance it, if you need to.) Note: you are writing the molecular, and not the net ionic equation. → NaCIO, (aq) + H₂O(1) X ローロ Ś
