what is universal solvent definition?
Generally, water is known as the universal solvent.
Water is known as the universal solvent because basically at the molecular level, salt basically dissolves in water due to electrical charges and due to the fact that both water and salt are the compounds which are polar, and with positive and negative charges on opposite sides in the molecule. It is true that universal solvent does not exist. Water is basically known as the universal solvent because it dissolves more chemicals than any other solvent. However, water is the solvent that only dissolves with other polar molecules.
This property of water usually allows the water molecule to become attracted to many other different types of molecules and it behaves as a solvent for every solute.

The color absorbed by a solution that appears the color given Green is Red.
The many colors we can see are caused by the various wavelengths that are present in the visible spectrum. We can recall the colors red, orange, yellow, green, blue, indigo, and violet by using the abbreviation "ROYGBIV." The figure below shows these in reverse order. Red is the least vibrant color, whereas violet is the strongest.
According to the graph, 550 nm light would appear green to us if it were shone upon us. White is made up of all the light wavelengths, hence it is not included in our visible spectrum.

The washing step of recrystallization removes which category of impurities?
The crystallization step of recrystallization removes the impurities present within the crystal lattice.
The washing step of recrystallization removes the impurities present on the surface of solid.
The solute crystallizes out when the solvent cools and the solution gets saturated with the solute (reforms a solid). Impurities are eliminated from the crystal lattice as the crystal grows, concluding the purification procedure. After that, the crystals can be gathered, cleaned, and dried.
Because the impurities won't crystallize quite yet and instead remain in the solution, the impure substance will crystallize in a purer form. The more pure crystals must now be separated using a filtration procedure. It is possible to repeat the process.

How many moles of nitrogen (N2) are required to produce 32.4 grams of NH3 ?
Answer: B
Explanation: Took the test
because biomass decreases by about 90% at each trophic level moving up.
The reason why biomass decreases by about 90% at each trophic level moving up is due to the inefficiency of energy transfer between trophic levels.
At each trophic level, organisms consume other organisms to obtain the energy they need to survive. However, as energy is transferred from one organism to another, some of it is lost as heat or used for metabolic processes like respiration, leaving less energy available for growth and reproduction.
The decrease in available energy is reflected in the decrease in biomass, which is the total amount of living matter in an ecosystem. As a result, there is less biomass at each successive trophic level. This pattern is sometimes referred to as the "pyramid of biomass."
In general, only about 10% of the energy available at one trophic level is passed on to the next trophic level, resulting in the 90% decrease in biomass at each level. This inefficiency of energy transfer is a fundamental characteristic of ecosystems and has important implications for the structure and function of ecological communities.

That means the nitrate ion has an overall charge of -1. The bond order of nitrate ion can be calculated using its Lewis dot structure. Bond order is the total number of bonds number of bonds group. In NO3- ion there are four N - O bonds and three bond groups.
