Answer:
Density
Explanation:
Density is a physical property that describes the relationship between mass and volume. Density is the amount of matter in a given space, or volume.
Answer:
The relationship between the mass and volume of a substance is known as its density. Density is defined as the mass of a substance per unit volume. In other words, it is a measure of how much matter is packed into a given space. The density of a substance is determined by dividing its mass by its volume. For example, if a substance has a mass of 10 grams and a volume of 2 cubic centimeters, its density would be 10 grams / 2 cubic centimeters = 5 grams/cubic centimeter. Density is an important physical property of substances, as it can be used to identify and classify different materials and understand their behavior.

Explanation:
consider the following tetra-substituted cyclohexane:
A colorless, movable liquid with a light, sweet smell is cyclohexane. In addition to being somewhat soluble in alcohol, acetone, benzene, ethanol, ethyl ether, olive oil, and carbon tetrachloride, it is also somewhat soluble in water.
Six groups are present in the equatorial regions and another six groups are present in the axial groups, making the chair conformation structure the most stable conformation structure.
As seen in figure 1 The chair conformation will be stable when the bigger atoms or groups are at the equatorial position. This is because there is relatively little steric interaction between the atoms or groups. The bigger atoms or groups that are present at the equatorial position do not interact sterically.
The chair conformation structure in figure 2 is the stable conformation structure. Because the adjacent groups to the bulky groups are present in the axial location and the equatorial position of the bulky groups, the groups do not interact with one another.

a 128 sample of oxygen gas reacts with excess nitrogen monoxide to form nitrogen dioxide gas. what volume of nitrogen dioxide will be produced at 273K and 101.3kPa (STP)
Answer:
To determine the volume of nitrogen dioxide gas produced when a sample of oxygen gas reacts with excess nitrogen monoxide, you need to know the balanced chemical equation for the reaction. Without this information, it is not possible to accurately calculate the volume of nitrogen dioxide produced.
In general, to determine the volume of a gas produced in a chemical reaction, you need to know the volume of the reactant gases and the mole ratios of the reactants and products in the balanced chemical equation. You can then use the ideal gas law to calculate the volume of the gas produced at a given temperature and pressure.
For example, if the balanced chemical equation for the reaction is:
2 O2 + 2 NO --> 2 NO2
and you know that you started with 128 g of O2, you can use the molar mass of O2 to convert the mass to moles, and then use the mole ratio from the chemical equation to determine the number of moles of NO2 produced. You can then use the ideal gas law to calculate the volume of NO2 produced at a given temperature and pressure.
I hope this helps! Let me know if you have any other questions.

What will be the ratio of rate of diffusion between o2 and h2?
4:1 will be the ratio of rate of diffusion between [tex]O_{2}[/tex] and [tex]H_{2}[/tex].
Graham's law for the diffusion of two gases is given as:
[tex]r_{1}[/tex]/[tex]r_{2}[/tex] = [tex]\sqrt{m_{2} /m_{1} }[/tex]
Substituting the molecular weights, 32 for 2 oxygen and 2 for hydrogen, we get the ratio of rates of diffusion of [tex]H_{2}[/tex]: [tex]O_{2}[/tex] = [tex]\sqrt{32/4}[/tex] = 4:1.
What is rate of diffusion?
Diffusion in gases is the random movement of particles involved in the net movement of matter from areas of high concentration to areas of low concentration. Particles in a particular gas keep colliding with other particles. In regions of the gas with the highest particle density, the particles bounce off each other, and at the boundaries of the container they bounce more than particles in regions of lower density.

what volume of a 0.291 m solutionof naoh is requreid to reach the equivalence point in a titration against 25 ml of 0.350 m hcl
The volume of a 0.291 m solution of NaOH required to reach the equivalence point in a titration against 25 ml of a 0.350 m HCl solution is 27.50 ml.
This can be calculated using the formula VNaOH
= (25ml) × (0.350 M HCl) / (0.291 M NaOH).
The volume of a 0.291 m solution of NaOH required to reach the equivalence point in a titration against 25 ml of a 0.350 m HCl solution can be calculated using the following equation:
VNaOH = (25ml) × (0.350 M HCl) / (0.291 M NaOH) VNaOH
= 27.50 ml
Therefore, the volume of a 0.291 m solution of NaOH required to reach the equivalence point in a titration against 25 ml of a 0.350 m HCl solution is 27.50 ml.
When a titration is performed, the equivalence point is reached when the moles of the acid is equal to the moles of the base. For an acid-base titration, the equivalence point is determined by the stoichiometry of the reaction between the acid and the base. In this case, the reaction between the 0.350 m HCl and the 0.291 m NaOH is
HCl + NaOH → NaCl + H2O.
The ratio of HCl to NaOH is 1:1, which means that when the moles of HCl is equal to the moles of NaOH, the reaction is complete, and the equivalence point is reached.

which balloon, a or b, most accurately illustrates the effusion of a gas from the central balloon?
Balloon A indicates accurately illustrates the effusion of a gas from the central balloon.
The root mean square velocity of orange molecules is greater. As a result, they travel faster than blue molecules. They are more easily able to escape from balloons than blue ones. As a result, balloon A (with less orange and more blue) indicates proper effusion.
The root means square velocity v is given by the formula v = (3RT/M)1/2,
So,
v is proportional to (1/M)^1/2
The effusion rate is proportional to ( 1/M)^1/2
As a result, the rate of effusion is proportional to v. ( room means square velocity)
Relative rate of effusion for orange spheres compared to blue spheres
