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.

What happens if you put some yeast and a pinch of sugar with warm water and a balloon ontop of the container and leave at for a week?

The yeast would consume the sugar and produce carbon dioxide gas as a byproduct. The gas would inflate the balloon, demonstrating the process of fermentation in action. After a week, you would likely see a visibly inflated balloon, indicating that the yeast has been actively fermenting.


What do you need for a yeast balloon experiment?

To conduct a yeast balloon experiment, you will need a balloon, a water bottle, warm water, sugar, active dry yeast, and a funnel. First, mix the warm water with sugar in the bottle, add yeast using the funnel, and stretch the balloon over the top of the bottle. As the yeast consumes the sugar and produces carbon dioxide, the balloon will inflate.


When puts water sugar and yeast into a balloon how the mass of the balloon will change?

As the yeast ferments the sugar, it produces carbon dioxide gas which fills the balloon. This process will increase the mass of the balloon due to the additional weight of the gas molecules inside.


Is sugar homogeneous or heterogenous?

Table sugar, sucrose, is a pure substance, so unless you are considering the air between its grains, it is homogeneous. Brown sugars are mixtures, so that will depend on how they are manufactured.


What can be a change in a yeast balloon experiment?

A change could be altering the amount of sugar or yeast used in the experiment to observe its effect on gas production. Another change could be varying the temperature at which the experiment is conducted to see how it impacts the rate of fermentation and gas production. Alternatively, changing the type of sugar used, such as switching from glucose to sucrose, can also yield different results in terms of gas production.

If you put water yeast and sugar in a bottle and put a balloon over the top the balloon will inflate. Will it inflate if you do NOT put sugar in it If not will anything happen at all?

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'

Does salt and yeast inflate a balloon?

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.


What happens when you put sugar and yeast inside of a ballon?

If there is a little moisture too, then the yeast cells will multiply and turn the sugar into alcohol and carbon dioxide gas. The carbon dioxide gas will inflate the balloon.


How do you inflate a balloon without blowing it?

you get a pin and jab itWhat you need to do is get a bottle and fill it with sugar and yeast and warm water. then let it stay like that for 2 to 3 hours. Or you could just blow it up using your mouth- much simpler! Or use a ballon pump


Will Salt Sugar Baking Soda Flour Or Baking Soda attract to a balloon?

Ordinary baking Soda usually will if slightly damp, but usually this never works unless the balloon is REALLY staticy....

Why cant salt and yeast make the balloon inflate?

As anyone who bakes bread, or brew wines and beers will know, yeast needs a moist, warm environment in which there is dissolved liquid sugar available (not salt). The yeast cells rapidly multiply as the yeast feeds off the sugar, and gives off carbon dioxide gas and alcohol. It is the carbon dioxide gas that will inflate the balloon. Salt would probably kill off the yeast.
