Answer:
The balloon becomes inflated
Explanation:
The equation of the reaction between baking soda (sodium bicarbonate) and vinegar(ethanoic acid) is shown below;
NaHCO3 + HC2CH3O2 ------> NaC2H3O2 + H2O + CO2
The gas (CO2) evolved in the process leads to the inflation of the balloon dropped on the bottle in which the reaction is taking pace.
This observation provides evidence that a gas was really evolved in the reaction.
Answer:
Density = 0.17 g/L
Explanation:
It is given that,
Volume of the inflated balloon filled with Helium,
Mass, m = 374 g
We need to find the density of helium. It is equal to its mass per unit volume. It can be given by :
d =m/V
So, the density of helium in the balloon is 0.17 g/L.
Here h2co3 is reduced because it oxidizes nh3
