This equation shows the neutralization of sodium hydroxide and hydrochloric acid: NaOH + HCl → H2O + NaCl

The reactant side of the chemical equation has (1/2/3/4) atom(s) each of sodium, oxygen, and chlorine. The reactant side also has (1/2/3/4) hydrogen atom(s). Count the numbers and kinds of atoms on the product side of the equation. The numbers and kinds of atoms on both sides of the chemical equation are (the same/not the same). So, this chemical equation is (balanced/not balanced) .

In a laboratory experiment, a fermenting aqueous solution of glucose and yeast produces carbon dioxide gas and ethanol. the solution was heated by burning natural gas in a bunsen burner to distill the ethanol that formed in the flask. during the distillation, the ethanol evaporated and then condensed in the receiving flask. the flame of the burner was kept too close to the bottom of the flask and some of the glucose decomposed into a black carbon deposit on the inside of the flask. during this experiment the following changes occurred. which of these changes involved a physical change and not a chemical change? check all that apply. 1-condensation of ethanol 2-evaporation of ethanol 3- formation of carbon dioxide gas from glucose burning of natural gas 4-formation of ethanol from glucose by yeast 5-formation of a carbon deposit inside the flask
