NaHCO3( s) + HC2H 3O 2( aq) → H2O (l) + CO2( g)+ NaC2H 3O 2( aq)

1. If you wanted to create the “best” volcano from this reaction, what are some things that you
would be looking for?

Can someone me with questions 12 and 13 plz.

Ahypothesis must be testable and falsifiable to be considered scientific a. trueb. false

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
