A helium balloon has a volume of 2.30 L at 23.5 ​o​C and a pressure of 1.00 atm at sea level. The Balloon is released and floats upward. At a certain height the atmospheric pressure is 0.810 atm and the temperature is 12.0 ​o​C. Calculate the volume of the balloon.

Answer 1
Answer:

Answer:

27.3 L

Explanation:
Answer 2
Answer:

Final answer:

To calculate the volume of the balloon at a certain height, we can use the combined gas law. The volume of the balloon at the new height is approximately 1.13 L.

Explanation:

To solve this problem, we can use the combined gas law, which states that the ratio of the initial pressure, volume, and temperature will be equal to the ratio of the final pressure, volume, and temperature.

Using the formula PV/T = constant, we can set up the equation (1.00 atm * 2.30 L) / (23.5 + 273.15 K) = (0.810 atm * V) / (12.0 + 273.15 K), where V is the volume of the balloon at the new height.

Simplifying the equation and solving for V, we find that the volume of the balloon at the new height is approximately 1.13 L.

Compared to a 26-gram sample of NaCl(s) at STP, a 52-gram sample of NaCl(s) at STP has(1) a different density(2) a different gram-formula mass(3) the same chemical properties(4) the same volume

Answers

The answer is (3) the same chemical properties. The two samples are under same condition so they have same density. The gram-formula mass is the property of the matter itself. So it will not change. The volume will change when mass changes.

A substance that contains only one kind of matter is known as a(n)A. atom.
B. element.
C. molecule.
D. compound.

Answers

Answer: B. element.

Explanation:

An atom is the smallest unit of any matter which may or may not have independent existence.

Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Copper (Cu)

Molecule is the smallest unit of any matter which always have independent existence.

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water CO_2
Elements are composed of only one type of atom, so element is the term you need

What is c2h5oh and the difference between it and c2h6o

Answers


-Physical condition: C₂H₅OH is liquid; CH₃OCH₃ is a gas.
-Reactivity: C₂H₅ reacts with sodium (Na) metallic, releasing H₂ and forming the sodium  ethoxide, Na (+) C₂H₅-O (-) (C₂H₅ONa).CH₃OCH₃ no reacts with sodium.-water solubility: C₂H₅OH dissolves in any proportionCH₃OCH₃ is poorly soluble in H₂O.
-polarity: C₂H₅OH is very polar, form hydrogen bonds.CH₃OCH₃ is little polar, doesn't have H available to form hydrogen bridge.
Write C₂H₆O may cause ambiguity because there are 2 different substances with this formula:-ethyl alcohol or ethanol = CH₃---CH₂---H
methyl ether = CH₃---O---CH₃

If you label a bottle only with C₂H₆O, will be very difficult to know if the compound is methyl ether or ethanol, which can be very dangerous in the laboratory. As only the ethanol C₂H₅OH is structured, it is convenient to use preferably this formula. For the methyl ether, it is more efficient to use the formula CH₃OCH₃.

What is a base-conjugate acid pair?

A base-conjugate acid pair simply means a pair that consist of two substances that only differ by the presence of a proton (H+).

In this case, the example of base-conjugate acid pair is NH3 and NH4+ because bNH4+ is the conjugate acid of the base NH3.
