Baking soda, or sodium bicarbonate (NaHCO3), undergoes a decomposition reaction when heated. Sodium bicarbonate breaks down and forms sodium carbonate (Na2CO3), water and carbon dioxide. Sodium carbonate is highly used in the production of soaps, paper, and glass. How many grams of sodium bicarbonate do you start with if you have 5.97693 x 10^26 units of sodium bicarbonate.

The covalent compound acetylene, which is the fuel of the oxyacetylene torch used by welders, has the molecular formula c2h2. the covalent compound benzene, a commercial solvent, has the molecular formula c6h6 each of these covalent compounds contains carbon and hydrogen atoms in a one-to-one ratio. would it be correct to write the chemical formulas of each as ch? explain.

For each of the following compounds, write the formula then predict whether it would be a strong, weak, or non-electrolyte when placed in di water. for the ionic compounds only, put (s) or (aq) after the forrmula formula strong, weak or non electrolyte? a calcium hydroxide b. silver carbonate c. lead(ii) sulfate d. phosphorus trifluoride e. sodium phosphide f barium sulfate g. strontium acetate h. zinc nitrate
