Q & A
What are the main materials used in the first part of the experiment?
-The main materials used in the first part of the experiment are a balloon, an empty bottle, a funnel, gloves, a face mask, a lab gown, vinegar, and baking soda.
What is the objective of the first experiment?
-The objectives of the first experiment are to understand Dalton's law of partial pressures, to determine the individual pressure of each gas, and to prove that the total pressure of a gas is the sum of the partial pressures of each individual gas.
How is the balloon filled with baking soda in the experiment?
-The balloon is filled with baking soda by using a funnel to pour the baking soda into the balloon.
What happens when the balloon filled with baking soda is placed on top of the vinegar-filled bottle?
-When the balloon filled with baking soda is placed on top of the vinegar-filled bottle, the two react to produce carbon dioxide gas, which causes the balloon to expand.
What is the purpose of gloves, face masks, and lab gowns in the experiment?
-Gloves, face masks, and lab gowns are used in the experiment to protect the experimenter from unnecessary exposure to chemicals.
What is Dalton's law of partial pressures?
-Dalton's law of partial pressures states that the total pressure exerted by a mixture of non-reactive gases is equal to the sum of the partial pressures of the individual gases.
What is the role of vinegar in the experiment?
-Vinegar plays a role in the experiment by reacting with baking soda to produce carbon dioxide gas, which is used to demonstrate the concept of partial pressures.
How is the hydrogen peroxide mixed with bleach in the second part of the experiment?
-In the second part of the experiment, the hydrogen peroxide is mixed with bleach by pouring it into a bottle filled with bleach and then shaking the bottle to mix the chemicals.
What gas is produced when hydrogen peroxide and bleach are mixed together?
-When hydrogen peroxide and bleach are mixed together, they produce oxygen gas.
What is the significance of the balloon expanding in the experiment?
-The expansion of the balloon signifies the production of gas and an increase in pressure within the bottle. The size of the balloon indicates the amount of pressure produced by the chemical reaction.
How does the experiment demonstrate the total pressure of different gas mixtures?
-The experiment demonstrates the total pressure of different gas mixtures by showing that the final balloon size, which is the result of mixing oxygen and carbon dioxide, is larger than the balloons from the individual reactions, indicating the sum of the partial pressures.

🧪 Experiment with Vinegar and Baking Soda
The script outlines a chemistry experiment using balloons, empty bottles, funnels, gloves, masks, lab gowns, vinegar, and baking soda. The goal is to understand Dalton's Law of Partial Pressures and to measure individual gas pressures. The procedure involves filling a bottle with vinegar, a balloon with baking soda, attaching the balloon to the bottle, and shaking to mix the contents. The experiment demonstrates the creation of carbon dioxide gas, visible through the balloon's expansion.
🔬 Hydrogen Peroxide and Bleach Reaction
This paragraph describes a second experiment using hydrogen peroxide, bleach, vinegar, and baking soda. The objectives are to comprehend Dalton's law, determine individual gas pressures, and prove the total pressure of mixed gases. The process includes filling bottles with bleach and hydrogen peroxide, using a funnel to avoid spills, and mixing the chemicals to produce oxygen gas. The experiment concludes by comparing the total pressure of oxygen and carbon dioxide gases, showing a larger balloon as a result of the combined pressures.

objective
first is to better understand the
concept of dalton law of pressure
second is to determine the individual
pressure of each individual gases
truth is to prove the total pressure of
a gas is the sum of the partial pressure
of each individual gases
the procedures
first prepare all the materials second
get the bottle and fill it with less
than vinegar
[Music]
[Music]
third with the use of funnel fill the
balloon with baking soda
[Music]

fourth put the balloon filled with
baking soda on the top of the bottle
with vinegar
[Music]
and lastly shake the bottle to mix it up
wait until the balloon expands
[Music]
in
conclusion when vinegar and baking soda
are mixed together it creates a carbon
dioxide gas and form a bubbles their
action of two ingredients was quickly
visible after they mix together in
addition the pressure of carbon dioxide
drop in the balloon as soon as the
balloon is placed on the top of the
bottle letting us know the amount of the
pressure by the size of the balloon
today we are going to make an experiment
and these are the materials
and let's go
for the first material these are the two
pieces of balloon
provide also a two pieces of empty
bottles
and we will also use a funnel
we will use gloves to protect our hands
from chemicals
face masks to prevent us from smelling
unnecessary smells from chemicals
and we should also provide a lab gown
we have here the hydrogen peroxide and
beach as a primary materials for this
experiment
vinegar and baking soda is also our
primary materials
and that's all the materials that we
will need
we have three objectives for this first
experiment the first one is to better
understand the concept of dalton's law
to determine the individual pressure of
each gases and to prove that the total
pressure of a gas is the sum of the
partial pressures of individual
gases
after we get all the needed materials we
will get a two bottles and fill the
other bottle with an ample amount of
bleach
while pouring the bleach in the bottle
we will use a funnel to avoid spilling
the bleach on the table
after pouring the bleach in the bottle
we will fill the balloon with a hydrogen
peroxide
[Music]
again we will use a funnel to properly
pour the hydrogen peroxide inside the
balloon
[Music]
we will now place the balloon at the top
of the bottle by opening the mouth of it
widely but carefully
[Music]
after that we will now pour the hydrogen
peroxide inside the bottle
we need to shake the bottle to mix up
the chemicals in it
and this is the result of the mixture of
hydrogen peroxide and bleach
[Music]
in conclusion to that when hydrogen
peroxide and bleach are mixed together
it will create an oxygen gas and it will
form a bubbles in order to make this
experiment possible the bleach must
contain sodium hypochlorite as soon as
the two ingredients are mixed together
the reaction quickly occurs and the
amount of pressure of gas was visible in
the size of the balloon
for this part we need to grab a new
bottle and fill it with vinegar and
baking soda
[Music]
we will use a funnel again to avoid
spilling the materials on the table
we will now take out the balloon from
the bottle of hydrogen peroxide and
bleach mixture
[Music]
we will now fill the bottle with baking
soda
then carefully put the balloon at the
top of the bottle
and shake the bottle to mix it up until
the balloon expands
[Music]
[Applause]
[Music]
this will be the result of total
pressure of oxygen gas and carbon
dioxide
in conclusion this experiment proves
that when you add the partial pressures
of different mixtures example given
oxygen gas and carbon dioxide the result
would be the total pressure of the two
mixtures in the last experiment you
would notice that the last balloon was
bigger than the
first one because it is the total
pressure of oxygen gas and carbon
dioxide
