According to Boyle's law, temperature being constant the volume of the balloon at pressure 3.3 atmospheres is 138.18 ml.
What is Boyle's law?Boyle's law is an experimental gas law which describes how the pressure of the gas decreases as the volume increases. It's statement can be stated as, the absolute pressure which is exerted by a given mass of an ideal gas is inversely proportional to its volume provided temperature and amount of gas remains unchanged.
Mathematically, it can be stated as,
P∝1/V or PV=K. The equation states that the product of of pressure and volume is constant for a given mass of gas and the equation holds true as long as temperature is maintained constant.
According to the equation the unknown pressure and volume of any one gas can be determined if two gases are to be considered.That is,
P₁V₁=P₂V₂
Substitution in above equation gives, V₂=1×456/3.3=138.18 ml.
Thus, the volume of balloon is 138.18 ml.

How does warmer planet causes ice to melt and then cause the warm up even more?
Answer:
Melting ice causes more warming.
Because they are darker in color, the ocean and land absorb more incoming solar radiation, and then release the heat to the atmosphere. This causes more global warming. In this way, melting ice causes more warming and so more ice melts.

which nonmetal has the greatest chemical activity?
Answer:
element fluorine
Explanation:
Since the noble gases are a special group because of their lack of reactivity, the element fluorine is the most reactive nonmetal. It is not found in nature as a free element. Fluorine gas reacts explosively with many other elements and compounds and is considered to be one of the most dangerous known substances.

In a reaction, the theoretical yield was 80 g, but the actual yield was 60 g. What was the percentage yield?
Answer:
75%
Explanation:
percent yield is the actual yield divided by the theoretical (predicted) yield, then multiplied by 100 to get a percentage.
60/80 = 0.75
0.75 x 100 = 75%
Answer:
33.34 %
Explanation:
Given that,
Actual yield = 60 g
Theoretical yield = 80 g
We need to find the percentage yield. It can be calculated as follows :
[tex]\%=\dfrac{Acutal-theoretical }{Actual}\times 100\\\\=\dfrac{60-80}{60}\times 100\\\\=33.34\%[/tex]
So, the required percentage yield is 33.34 %.

A balloon filled with helium has a volume of 30.0 L at a pressure of 100 kPa and a temperature of 15.0 C. What will the volume of the balloon be if the temperature is increased to 80.0 C and the pressure remains constant? (Hint: Use the Charles law equation)
Answer:
The final volume of the balloon is 24.480 liters.
Explanation:
Let consider that no leakages occur in the balloon during the isobaric process and that helium behaves ideally. From Equation of State for Ideal Gases, we construct the following relationship:
[tex]V_{o}\cdot T_{o} = V_{f}\cdot T_{f}[/tex] (1)
Where:
[tex]V_{o}[/tex], [tex]V_{f}[/tex] - Initial and final volume, measured in liters.
[tex]T_{o}[/tex], [tex]T_{f}[/tex] - Initial and final temperature, measured in Kelvin.
If we know that [tex]V_{o} = 30\,L[/tex], [tex]T_{o} = 288.15\,K[/tex] and [tex]T_{f} = 353.13\,K[/tex], the final volume of the balloon is:
[tex]V_{f} = \frac{V_{o}\cdot T_{o}}{T_{f}}[/tex]
[tex]V_{f} = 24.480\,L[/tex]
The final volume of the balloon is 24.480 liters.

A scuba diver swims deeper and deeper into the ocean. What happens to the nitrogen in her blood as she goes deeper
Answer:
it compresses under the pressure.
Explanation:
when she comes up, it will re-expand as pressure goes down- this is why they have to be very careful how fast they come back up.
Answer:
If a diver goes through too great of pressure change too quickly, their body cannot eliminate all of the expanding nitrogen and the excess nitrogen forms bubbles in their tissues and blood. These nitrogen bubbles can cause decompression sickness (DCS) by blocking blood flow to various parts of the body, causing strokes, paralysis, and other life-threatening problems.
Surface tension _____. A. Causes beads of water to spread out B. May be increased by detergents C. Is an inward force that tends to minimize the surface area of a liquid D. Is decreased by hydrogen bonding
Answer:
C. Is an inward force that tends to minimize the surface area of a liquid
Explanation:
Surface tension is a skin-like proper of water that is explained by its property or ability to form hydrogen bonds. The water molecule has the ability to bind the molecules from all sides that surrounds it. The force of action on each of the molecules is balanced. The surface tension is a more inward phenomenon and it holds the droplet in a spherical shape.if you mix the two liquids, propanol and vegetable oil, are they miscible or immiscible?
Answer:
it would be immiscible
Explanation:
They would not mix similar to oil and water

Most hot air balloons are round. Yes, you can have some other shapes like this one, but its shape is still rounded. Using the assumptions, explain why a square hot air balloon would be hard to make.
A square hot air balloon would be hard to make because the round shape of traditional hot air balloons allows for even distribution of heat, which is necessary to maintain the balloon's lift and stability.
What is a hot air balloon ?A hot air balloon is a balloon filled a heated air which can rise above the atmosphere. In a round balloon, the heat from the burner is evenly distributed around the circumference of the balloon, causing the air inside to heat up and rise, which in turn causes the balloon to lift.
If a hot air balloon were to be made in a square shape, the heat would be distributed unevenly and concentrated in certain areas. This could cause the balloon to become unstable, as the hot air would rise in some areas but not others, leading to uneven lifting and potential loss of control.
Additionally, the corners of the square shape would be more susceptible to damage and could create weak points in the structure of the balloon.
Therefore, while it is possible to create hot air balloons in other shapes, the traditional round shape has been found to be the most effective and efficient for maintaining the necessary heat distribution and stability required for safe and successful flight.
