Liquid has a fixed volume: The particles of liquid are held close togetherSolid: Solid has a definite volume and shape
This means that matter in the solid state takes the shape of whatever container it is.If it takes the shape of its container, it then means that it also has a fixed volume.Gas: Neither a definite shape nor volume.
This means that gas as a state of matter has no definite shape. It has also no definite volumePlasma: No fixed shape or volume.

How many moles of N are in 0.207 g of N₂O?
Number of moles of N in 0.207 g of N₂O= 0.0094
We are starting with 0.207g of N₂O in this instance. Let's use the molar mass, which is 44.013 g/mol, to convert that to moles.
(1 mol N₂O / 44.013 g N₂O) x 0.207 g
⇒ 0.00470 mol N₂O.
Having reached moles of nitrogen monoxide, we must now determine how many moles of nitrogen there are. We can see that there is a subscript of 2, indicating that there are two moles of nitrogen for every mol of nitrogen dioxide. You might think of it in terms of food; there are two pieces of bread for every sandwich.
In order to obtain moles of N, let's multiply the amount of moles of N₂O by 2.
(2 mol N / 1 mol N₂O )x 0.00470 mol N₂O = 0.0094 mol N.
Hence, Number of moles of N in 0.207 g of N₂O will be 0.0094.

How many silver atoms are there in 3.74 g of silver?
Express your answer using three significant figures.
2.01214904 × 10²² silver atoms are there in 3.74 g of silver
The most common isotope of silver has 60 neutrons, 47 protons, and 47 electrons. Silver is a soft metal with a glossy metallic luster under normal circumstances. It is exceedingly malleable and ductile (can be formed into a wire).
The molar mass of silver is as follows:
Molar mass of Ag = 107.8682 g/mol
The number of atoms in a molar mass is Avogadro’s number:
6.022140857 × 10²³
Therefore 3.8 g of silver contains 3.8 times 6.022140857 × 10²³ divided by 107.8682 that equals 0.03522818 times
6.022140857 × 10²³

Calculate the molarity, Molality, and mass percent concentration of the solution.
The molarity of the solution is 0.023 M and the molality of the solution is 17.9 m.
What is the molality?The concentration of a solution is defined as the amount of substance in a solution. Now we are told that we have a solution of 2.64 L aqueous solution of KOH. The solution has a density of 1.29 g/mL.
Density of the solution = 1.29 g/mL

which stament best explain why the dog is able to see the object more the rabbit can
Answer:
The position of their eyes
Explanation:
See, the dog is able to see the object more than the rabbit can is because of the position of their eyes.
The dogs eyes are positioned in the front like our eyes making the dog have a stereoscopic vision (180 degree field of view)
With rabbits though, they can't really see what's in front of them because their eyes are on the side hence the dog can see the object more than the rabbit can.

The gas inside the bubbles that form in the boiling water is H₂O(g).
The gas inside the bubbles that form in the boiling water is mostly water vapor. The bubbles in the water vapor start to form on nucleation sites. The water vapor bubbles start to form larger as the temperature increases because more liquid is being converted to gaseous form. Vapor-filled bubbles shrink and disappear completely.
Therefore, when water is boiling the physical state of water, liquid changes to another state of water which is gaseous.
Hence, the bubble that we see in boiling water is the gaseous form H₂O(g) of water.

What is density?Density is the ratio of the mass to the volume of a body. We know that the density of the body is an intrinsic property. This implies that it does not change with the amount of substance or with the mass of the body. Let us now try to solve each of the problems.
1) Density = mass/volume
Volume = 1 cm * 3 m * 2 cm = 6 cm^3
Density of the body = 3 g/cm^3
Mass of the body = 6 cm^3 * 3 g/cm^3 = 18 g
2) To answer question 2, we have to remind ourselves of what we said that the density is the ratio of the mass to the volume of a body and that the density of a body is constant. This implies that the relationship that defines the relationship of the mass to the density of the material does not change and this is shown by option C.

A piece of metal with a mass of 15.45 g is added to 21.27 mL of water in a
graduated cylinder. The water level rises to 24.78 mL. The density of the metal
is
g/mL.
Hint: You need to apply the significant figure rule for subtraction first; then apply
the significant figure rule for division. Do not round until the end!
Enter your answer as number without a unit.
The density of the object is 4.4 g/mL.
What is density?The term density refers the ratio of the mass of the mass to the volume of a body. The density of a body is a constant as it does not change irrespective of the mass or the volume of the object in at any given time. We have now been told that the former volume of the water was 21.27 mL. The addition of the object increased the volume of the object to about 24.78 mL.
Let us recall that is common to obtain the volume of a solid by the displacement method. The volume of the substance before and after the addition of the solid is recorded. The volume of the solid is taken to be the volume of the liquid that is displaced since the solid must displace its own volume of liquid.
Hence we have;
Mass = 15.45 g
Volume = 24.78 mL - 21.27 mL = 3.51 mL
Density = 15.45 g/3.51 mL
= 4.4 g/mL

An atom of sodium -23 has a net charge of +1 identify the number of protons, neutrons, and electrons in the atom. Then explain how you determine the number of each type of particle. Use the periodic table to help
The number of each type of particle is:
The number of protons is 11
The number of neutrons is 12
The number of electrons is 10
A proton is a stable subatomic particle with the symbols p, H+, or 1H+ and an electric charge of +1 e. Its mass is 1836 times greater than that of an electron and only slightly less than that of a neutron. Every atom's nucleus contains one or more protons. The defining characteristic of an element is its atomic number, which is the number of protons in its nucleus (represented by the symbol Z).
The neutron, symbol n or n0, is a subatomic particle with a neutral charge and slightly more mass than a proton. Atomic nuclei consist of protons and neutrons. With the exception of the hydrogen nucleus, which has a single proton, neutrons are necessary for the stability of nuclei. Nuclear fission and fusion generate a ton of neutrons.
For a neutral Na, Sodium atom:
The mass number P+N = 23
Atomic number (E or P) = 11
A charged Na atom that has lost an electron is positively charged and so: Number of Protons = 11 (Still the same)
Number of neutrons = 12

compressed
temperature
The final temperature of the canister is 312.76 degrees celsius.
The relation between temperature and pressure is given by the Gay Lusaac’s Law.
According to this law at constant volume, pressure is directly proportional to the temperature.
Mathematically it is as follows,
Pressure (P) ∝ Temperature(T)
P = K T
P/T = K(constant)
Thus the ratio of P/T will remain the same if volume remains constant.
So, P1/T1 = P2/T2
Here P1= initial pressure of the canister = 97.2 kPa = 0.95 atm
P2 = Final pressure of the canister = 1.88 atm
T1 = Initial temperature = 23 c = 296 K
T2 = Final temperature = ?
Putting these values
0.95/296 = 1.88/T2
T2 = 585.76 K or 312.6°C.
Thus, the final temperature of the canister is 312.76 degrees celsius.
