Trini adds 10g of baking soda to 100g of vinegar. the mixture begins to bubble. when the bubbling stops, trini finds the mass of the resulting mixture. she determines that the mass is 105g. how do you know that a chemical change has occurred?

Parce que lorsque le bicarbonate de soude réagit avec le vinaigre, il produira du CO2 qui est une phase gazeuse .. Et ce CO2 s'évaporera de

NaHCO3 (s) + CH3COOH (aq) → CH3COONA (aq) + CO2 (g) + H2O (l), de

sorte que la masse diminuer parce que le CO2 s'évaporera

i think it's they require warm air
