Draw a model to explain why the stream of hexane does not bend when the negatively
charged rod gets close to it.

Solutions of sodium carbonate and silver nitrate react to form solid silver carbonate and a solution of sodium nitrate. a solution containing 3.50 g of sodium carbonate is mixed with one containing 5.00 g of silver nitrate. how many grams of sodium carbonate, silver nitrate, silver carbonate, and sodium nitrate are present after the reaction is complete?

What is the ph of a solution that has a hydrogen ion concentration of 1.0 * 10 -9 m?

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.
