Conservation of mass and energy.
You put in a certain amount of one or more reactants and if there is a chemical change, the new substance(s) will have net same mass-- Whether or not you can see it. Using the balloon is a good example to demonstrate conservation of mass and energy, because the balloon captures the gas given off of the chemical reaction between the two starting reactants.
Yeast consumes sugar and releases a gas called carbon dioxide. If this preparation is developed in a bottle and a balloon fixed over the neck of the bottle, the carbon dioxide will inflate the balloon
The reaction that takes place between the two compounds leads to the evolution of carbon dioxide gas which infiltrates the balloon and blows it up.
The vinegar (a solution of acetic acid) and baking soda (sodium bicarbonate) react to form sodium acetate, water, and carbon dioxide. The carbon dioxide is the gas that fills the balloon.

It does NOT produce CO2
Yeast of course, beer bottle, water, balloon and sugar maple syrup.
Live yeast can be used to inflate a balloon if you give the yeast something to ferment (such as sugar). They then produce carbon dioxide as a waste product that could inflate a balloon. You should not expect it to be buoyant, however, for CO2 is heavy as gases go (considerably heavier than air, for instance). The yeast cannot use salt for much of anything, however.
The sugar is needed as food for the yeast. The yeast gives off carbon dioxide as it digests the sugar. The carbon dioxide could be used to inflate the balloon. Without the sugar, the yeast remains dormant and does not give off carbon dioxide.
Presence of sugar in the both bottles
Personally. the yeast in the balloon experiment would be more interesting.
how would a balloon payment effect interest on a loan
temperature (30 degrees celcius is the optimum temp for yeast growth), nutrients (e.g. sucrose, fructose, glucose, lactose - (does not affect yeast growth), pH level (5 - 6 is the optimum pH level for growth)
the balloon will inflate
Directly regulated by sugar and salt. Sugar cuases yeast growth, salt slows. Environmental factors such as moisture, heat and acidity also affect yeast growth.
no because there is no material yes it can who ever said no!
yeast! people why are you sooooo stupid?
