How specifically is kinetic energy lost during a car crash?
Answer + Explanation:
During a car crash, kinetic energy is lost through various forms of deformation of the vehicle and the generation of heat.
When a car collides with another object, the force of the impact causes the vehicle's body and structure to deform. This deformation absorbs some of the kinetic energy and converts it into other forms of energy, such as heat and sound.
In addition, friction between the moving parts of the car and between the car and the road can also generate heat, which absorbs some of the kinetic energy.
The amount of kinetic energy lost during a car crash depends on the mass of the vehicle, the speed at which it was traveling, and the type and severity of the collision. In general, higher speeds and more severe collisions result in greater kinetic energy loss.

D.

If one form of a gene can mask the appearance of another form, that form is considered dominant over the other form. Option B.
What are dominant alleles?According to Mendel, genes are usually made up of 2 alleles. These alleles can be the same or different. When the alleles are the same, the gene is said to be homozygous. If the alleles are different, the gene is said to be heterozygous.
When the two alleles that make up a gene are different, one will be dominant and the other will be recessive. The dominant gene masks the effect of the recessive gene. In other words, the recessive gene cannot be expressed as long as it coexists with the dominant gene. In order for it to be expressed, it has to be in two copies or a homozygous recessive form.
For the dominant allele, however, only one copy is needed for it to be expressed.
In summary, if one form of a gene can mask the appearance of another form, that form is considered dominant over the other form.

what is the relationship between the edge length of a unit cell and atomic radius in a hexagonal closest packed crystal structure?
In essence, it refers to the measure of the length of the edge (side) of spatial figures like cubes, cuboid, and polygons as well as quadrilaterals and other 3D shapes.
For the FCC lattice, the relationship among edge length (a) with atom radius (r) is ( 2a) = 4r. For the BCC lattice, the relationship among edge length (a) with atom radius (r) is (3a) = 4r. Here, r represents the radius of a atom in the HCP, and a denotes the area of the unit cell. - Assume that each atom's radius is r. Consequently, the product of a base area and the height will be the unit cell's volume (C). Atoms in this unit cell's neighboring corners come into contact with one another, hence its edge length is equivalent to two ionic radius, and one atomic diameter.

on heating 0.56g of copper [ll] Bromide decomposed to give 0.36g of copper [l] bromide and some bromine.How many moles of bromine molecules were given off.
Answer:
To find the number of moles of bromine molecules that were given off, you need to know the atomic masses of copper and bromine. The atomic mass of copper is 63.55 g/mol and the atomic mass of bromine is 79.904 g/mol.
First, you need to calculate the number of moles of copper bromide that was decomposed. You can do this by dividing the mass of copper bromide by its atomic mass: 0.56 g / (63.55 g/mol + 79.904 g/mol) = 0.01 mol.
Next, you can use the balanced chemical equation for the decomposition of copper bromide to determine the ratio of bromine molecules to copper bromide molecules. The balanced chemical equation is:
CuBr2 -> Cu + Br2
This equation shows that for every one molecule of copper bromide that decomposes, two molecules of bromine are produced.
Finally, you can use the number of moles of copper bromide and the ratio of bromine molecules to copper bromide molecules to calculate the number of moles of bromine. In this case, there are 0.01 mol of copper bromide and 2 molecules of bromine are produced for every 1 molecule of copper bromide, so the number of moles of bromine is 0.01 mol * 2 molecules / 1 molecule = 0.02 mol.
Therefore, 0.02 moles of bromine molecules were given off when 0.56 g of copper bromide decomposed.
Explanation:
-0.0009 moles of bromine molecules were given off.
To determine the number of moles of bromine molecules that were given off during the decomposition of copper [II] bromide, you need to know the molar masses of copper [II] bromide and copper [I] bromide, as well as the mass of copper [I] bromide produced during the decomposition.
The molar mass of copper [II] bromide is 223.66 g/mol, and the molar mass of copper [I] bromide is 200.07 g/mol. The mass of copper [I] bromide produced during the decomposition is 0.36 g.
To determine the number of moles of bromine molecules that were given off, you can use the following steps:
Calculate the mass of copper [II] bromide that was decomposed by subtracting the mass of copper [I] bromide produced from the original mass of copper [II] bromide: 0.56 g - 0.36 g = 0.20 g
Calculate the number of moles of copper [II] bromide that was decomposed by dividing the mass by the molar mass: 0.20 g / 223.66 g/mol = 0.00089 moles
Calculate the number of moles of copper [I] bromide produced by dividing the mass by the molar mass: 0.36 g / 200.07 g/mol = 0.00179 moles
Calculate the number of moles of bromine molecules that were given off by subtracting the number of moles of copper [I] bromide from the number of moles of copper [II] bromide: 0.00089 moles - 0.00179 moles = -0.0009 moles
Note that the number of moles of bromine molecules that were given off is negative because the mass of copper [I] bromide produced during the decomposition is greater than the mass of copper [II] bromide that was decomposed. This means that some of the bromine molecules that were given off during the decomposition of copper [II] bromide were used to form the copper [I] bromide that was produced.
The final answer is -0.0009 moles.

what are the correct coefficients if the law of conservation of mass is applied to the decomposition of solid ammonium nitrite to nitrogen gas and liquid water?
The correct equations for the breakdown of solid ammonium nitrite to nitrogen gas and liquid water under the law of conservation of mass would be 1 mol of solid ammonium nitrite to 1 mol of nitrogen gas and 1 mol of liquid water.
Since matter cannot be generated or destroyed, according to the rule of conservation of mass, the total mass of the reactants and products in a chemical process must remain constant. The balanced chemical equation for the breakdown of solid ammonium nitrite is:
NH4NO2(s) N2(g) + H2O (l)
The coefficients in this equation stand for the ratio of moles of each reactant and product. According to the factors 1, 1, and 1, 1 mol of nitrogen gas and 1 mol of liquid water are created for every 1 mol of solid ammonium nitrite that is broken down. As required by the rule of conservation of mass, this indicates that the combined mass of the reactants and products remains constant.
Ammonium nitrite ,[tex]$\mathrm{NH} 4 \mathrm{NO}$[/tex], will decompose to yield nitrogen gas and water Vapor by the following equation:
[tex]\mathrm{NH}_4 \mathrm{NO}_2(s) \rightarrow 2 \mathrm{H}_2 \mathrm{O}(\mathrm{g})+\mathrm{N}_2(g)[/tex]

color of the solution in the control changed? 4) infer. when you began the experiment, was there co2 in the water? in the test tubes that contained elodea, where did the co2 go?
The water was, indeed, green. This signifies a low carbon dioxide level. Carbon dioxide was utilized in the photosynthesis activity in the tubes containing Elodea.
Carbon dioxide is a compound consisting of molecules that are covalently double bonded to two oxygen atoms. At ambient temperature, it appears to exist as just a gas. Carbon dioxide in the atmosphere is translucent to visible to the human eye but soaks up infrared light, acting as a greenhouse gas. Photosynthesis is the process that plants as well as other microbes use to convert chemical energy into light that can then be released to power the individual's activities via cellular respiration.
