diamonds are made of carbon atoms. enough said.

The relative rate constant is a ratio of the rate constants of two reactions in a chemical reaction mechanism. It is used to determine the rate of reaction between different reactants in relation to each other.

An example of distillation is the process of separating alcohol from water to produce spirits like vodka or whiskey. This is done by heating the mixture to create vapor, which is then cooled and condensed back into a liquid form.

The conversion factor to convert inches to "Nominal Bore" (NB) is 25.4 mm per inch. NB sizes are based on the internal diameter of a pipe, and they do not directly correlate to inches.

ELECTROFILIC REAGENTS:It is the combination of two words(electro means electron and phile means loving).Therefore those reagents that contain positive charge on it are called eletrophilic reagents. These reagents have the property of attacking on the negative part of the other substance.Some of the reagents are(NO2+ ,SO3+) NUCLEOPHILIC REAGENTS:Combination(nucleo means nucleus and phuile means loving)

Because alloys often have better properties than their parent metals. Stronger, rust resistant etc

Petrol is a flammable liquid mixture primarily derived from crude oil. It is commonly used as a fuel for internal combustion engines due to its high energy content. Petrol is volatile, easily ignitable, and highly combustible.

Atoms can be split through a process called nuclear fission, in which the nucleus of an atom is split into two or more smaller nuclei. This process releases a large amount of energy in the form of heat and radiation. Nuclear power plants use controlled nuclear fission reactions to generate electricity.

Sublevels of elements refer to the energy levels within an atom where electrons are found. These sublevels are designated by the letters s, p, d, and f. Each sublevel has a maximum number of electrons it can hold (2 for s, 6 for p, 10 for d, and 14 for f) and they are arranged in order of increasing energy within an atom.

In dyeing, the exhaust method refers to the process of adding dye to a textile substrate until all the dye has been absorbed by the substrate or bath. This method is useful for achieving full color coverage and intense color saturation on the fabric. The exhaustion of dye in the bath indicates that the dye has been fully utilized in the dyeing process.

Federal standards for city-supplied drinking water are governed by the Environmental Protection Agency (EPA) under the Safe Drinking Water Act, which sets limits on various contaminants. Commercial bottled water, regulated by the Food and Drug Administration (FDA), must meet the same quality and safety standards as tap water but is subject to different testing and monitoring requirements. Additionally, bottled water may be subject to labeling regulations that differ from those for tap water.

I do not have real-time data on the current price of dimethyl ether. Prices can vary based on location, supplier, and market conditions. It is recommended to check with local suppliers or online marketplaces for the most up-to-date pricing information.

An eductor is a device that uses a fluid (usually a liquid or gas) to create a vacuum or achieve a pumping action. It works based on the principle of fluid dynamics, where a high-velocity fluid stream entrains a lower-velocity fluid or solid material through a nozzle, generating a suction effect. Eductors are commonly used for tasks like mixing liquids, evacuating gases, and transporting solids in various industries.

The German passenger airship Hindenburg, filled with hydrogen gas, caught fire and was destroyed while attempting to land in Lakehurst, New Jersey in 1937. The disaster resulted in the death of 36 people and marked the end of the era of hydrogen-filled airships for commercial air travel.

Great question. The answer is almost certainly not. Gasoline is only 3/4 the density of fresh water. You could not float in it. As an addendum, by "staying afloat" the question implies effort as in treading, as one would tread water. Yes. But, because the viscosity of Gasoline is less than water it would take greater effort, more stamina and this causes heavier breathing. Beside the fact that gasoline is absorbed thru the skin and blisters, if help were not immediately forthcommiing, the noxious fumes would soon render one unconcious and thus result in drowning.

Under the ASTM Method D 323 (Reid vapour pressure), it is the absolute vapour pressure exerted by a liquid at 100°F. The higher this value, the more volatile the sample and the more readily it will evaporate. Unlike distillation data, vapour pressure provides a single value that reflects the combined effect of the individual vapour pressure of the different petroleum fractions in accordance with their mole ratios. It is thus possible for two wholly different products to exhibit the same vapour pressure at the same temperature - provided the cumulative pressures exerted by the fractions are the same. A narrow-cut distillate, for example, may exhibit the same vapour pressure as that of a dumbbell blend, where the effect of heavy fractions is counterbalanced by that of the lighter ones. In conjunction with other volatility data. Reid vapour pressure plays a role in the prediction of gasoline performance.

Rubber floor mats typically melt at temperatures around 250-300 degrees Fahrenheit. It is important to check the specific material and manufacturer guidelines for accurate temperature thresholds to prevent damage.

all temperatures above saturated steam is super heated steam.

"Superheated" steam isn't so much a scientific term as a technical term. Steam is more efficient the more energy it has (the molecules have more kenetic energy/are hotter).

During the height of steam locomotive development, the most fuel efficient way to accomplish this was to collect the steam, and then run it through a series of loops that are exposed to the exhaust gases of the original combustion, there-by further heating the steam.

Because the steam receives no further moisture, but received further heat energy, it is considered 'dry' steam. Superheat was a term coined by the engine builders as a way to promote the design as a way to sell their engines.

Because the superheater pipes carried steam pressure, they added additional equipment that had to be inspected as per ICC regulations. Because they also were exposed to the exhaust gas stream, they had a likelyhood of being erroded by the waste fuel being exhausted as well as the 1300+ degree combustion exhsut gasses.

Petroleum jelly is used in the hang drop procedure because , it reduces the evaporation of the drops of fuild . ----------------------

ALSO, this type of sealing material is used primarily to not only reduce evaporation of liquid but to eliminate air current in the preparation as well.

It is made of specially cohesive material on one side, and other non-stick material on the other side, giving tape its ability to stick. However, all of the cohesive products are not released to the public, since they are mostly secret.
