The gas that is given out during the reaction of baking soda and coke could inflate a balloon
If you wanted to inflate it with carbon dioxide, sure, you could do that. It's not an especially efficient way of doing so.
To inflate the balloon. Whether the gas is helium or just air from your lungs, gases are needed to inflate the balloon.
Inflate it with water.
You get a soccer ball pump needle a stick it into a balloon and it will inflate
-- Inflate the balloon with some substance that is less dense than air. OR -- Inflate the balloon with air, then heat it after it is sealed.
Vinegar is an acid and baking soda is an alkali. If an acid and an alkali react with each other they produce a salt, water and hydrogen gas. the gas produced can be used to inflate the balloon.
Yes it will.
The pressure inside the balloon has to exceed the pressure outside the balloon.
Yes, but it will not inflate very much
Yeast eats the sugar giving off CO2 which is a gas that will inflate the balloon. Added: But since carbon dioxide is heavier than air this balloon gas will never reach the 'top'
yes it will!
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.
