Answer:
We can measure volumes approaching absolute zero and then predict what the volume would be at absolute zero.
Since there is NO molecular motion at absolute zero, the volume of a balloon at absolute zero should be zero.
If you headed to the deepest recesses of intergalactic space, shielded from starlight, the only thing that would heat you up would be the Big Bang's leftover glow: the cosmic microwave background at 2olume.ht v725 K. At that temperature, the balloon would have a volume.
Charles' Law asserts that a gas's volume (V) and temperature (T), which must be expressed in Kelvin, are directly proportional to one another. A change in temperature of one Kelvin unit corresponds to a change in one Celsius degree. Never forget that the value 0 on the Kelvin scale corresponds to -273 or "Absolute Zero."
What will the volume be at absolute zero, and how can we calculate it?Charles's Law, V = a T+ b, is used to calculate absolute zero once the mass measurements are transformed to high and low temperature gas volumes.
The volume of an ideal gas would theoretically be 0 at absolute zero, and there would be no more molecular motion. Actually, above this temperature, all gases condense into solids or liquids.
According to Boyle's Law, gas volume grows as pressure lowers. Charles' Law states that when the temperature rises, the volume of the gas increases.
Gases compress infinitely as the temperature is lowered because there is a linear relationship between temperature and pressure for the majority of gases (see gas laws). The volume of an ideal gas would theoretically be 0 at absolute zero, and there would be no more molecular motion.

what is the relationship between gas particles and pressure
Answer:
For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant..

A book is held against a wall by applying a force perpendicular to the surface of the book. In a free body diagram of all of the forces acting on the book, what force would keep the book from sliding down the wall? A. force of hand B. force of gravity C. friction force D. normal force
In a free body diagram of all of the forces acting on the book, the force which would keep the book from sliding down the wall is; Choice A: Force of hand.
In modern mechanics, it is noteworthy to know that the normal force, F(n) is the component of a contact force which is perpendicular to the surface that an object contacts.In this instance, the surface which the object contacts is the wall.
It has however been stated within the question that;
A book is held against a wall by applying a force perpendicular to the surface of the book.In conclusion, the force which keeps the book from sliding down the wall is the force of the hand which is perpendicular to the object's surface of contact.

what is the molar mass of dimethylglyoxime, c4h8n2o2?
Explanation:
The molar mass of a compound can be calculated by finding the molar of the individual atoms that combine to make the compound.
Molar mass of compound =
∑ (molar mass of element × number of atoms of the element)
∴ Molar mass of dimethylglyoxime
= 4C + 8H + 2N + 2O
= [(4 × 12.011) + (8 × 1.0080) + (2 × 14.007) + (2 × 15.999)] g/mol
= 116.12 g/mol
∴ the molar mass of dimethylglyoxime = 116.12 g/molPlease tell me the answer, I will mark the first person to answer brainlist

Magnesium has an atomic (proton) number of 12 and a mass number of 24.
How many magnesium atoms are there in 2 moles of magnesium? HELPPPPP
Answer:
1.2044x10^24 atoms
Explanation:
one mole of any element has 6.022x10^23 atoms
so 2 moles is just multiplying avogadros number by 2
2 x ( 6.022x10^23)= 1.2044x10^24 atoms

Is this equation balanced? Explain why the equation S+3O2 → SO3 is balanced or is not balanced. Use four different words from the word bank to earn (4 points).
We can check if the equation is balanced by comparing the number of atoms of each element on the reactant and product sides. The reaction is only balanced if the number of atoms of each element is equal.
S + 3O₂ → SO₃
Reactant Product
S 1 1
O 6 3
∴ the equation is UNBALANCED since the number of atoms of oxygen on the reactant side is greater than that of the product.The balanced equation would be 2 S + 3O₂ → 2SO₃
Reactant Product
S 2 2
O 6 6

how do the melting points of enantiomers compare to each other? how do the melting points of diastereomers compare to each other?
Melting points of enantiomers will not compare to each other as they have same M.P. and Diastereoisomers are compared on the basis of melting point.
What are steroisomers?Stereoisomers are those isomers which are having the same molecular formula but different spatial arrangemet of atoms within the molecule.
Enantiomers: Enantiomers are pair of two stereoisomers which are having mirror image of each other, but are not superiposable. They have the same melting point so we can not compare enantiomers on the basis of their melting point.Diastereoisomers: Diastereoisomers are pair of those stereoisomers which are not having mirror image of each other, but are superimposable.They have different physical and chemical properties, so it can be compared on the basis of melting point.Hence, only diastereoisomers are compared on the basis of melting point.

Overlap of the electron clouds of two atoms results in a(n)
a hydrogen bond
b dipole
C ionic bond
d covalent bond
Check it
We know that the electron clouds of two atoms overlapping is a bond, because that signifies that the electrons are being shared in a bond.
So, I'm going to go through some definitions of these different types of bonds, because they have very specific circumstances.
A hydrogen bond is a bond between an electronegative atom and a hydrogen molecule (which is not what this question says, this isn't stated anywhere).
A dipole is a difference in electron density on two different atoms (so this isn't even close to what the question is stating, a dipole is not even a bond)
An ionic bond is an unequal sharing of electrons between two atoms (because the question doesn't state this specific fact, then it can't be this option).
By process of elimination, we know the answer is covalent bond, but just in case, we can also look at the definition of a covalent bond: a bond that involves the sharing of electrons between atoms.
That is exactly what the question is asking for! Therefore, your answer is d. covalent bond
