This is a two-part assignment and I don't have time to finish the first part. Would be cool if someone could help. Thanks. Also, would 2NaHCO3(s) = Na2CO3(s) + H2O(g) + CO2(g) be the balanced equation?

50 pts plz what is the physical state of matter of baking soda.

How many grams of oxygen gas are contained in a 15 l sample at 1.02 atm and 28°c? show your work.

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
