What is the best reason for using iron filings instead of an iron nail in a chemical reaction?
The best reason for using iron filings instead of an iron nail in a chemical reaction process would be that the filings would take less time to dissolve, because they are already in the smallest solid form they can be in. They are also more likely to have been stored in such a way that they are not contaminated by rust or other pollutants.
Adding cornflour to water is a physical change. The reason this process is classified as such is that it does not change the chemical identities of the substances involved, which is the criterion for a process to be considered a chemical reaction. Technically, the cornflour would slowly hydrolyze in water, which would be a chemical reaction.
What is the reason radioactive isotopes can be followed through the steps of a chemical reaction or industrial process?
A Biproduct or a chemical reaction is a substance(s) that is produced from the reaction. E.g. a product of Photosynthesis is Carbohydrates. a Biproduct is oxygen. Oxygen is not the reason or purpose of the the reaction, yet it is produced non the less as a bi product: 6H2O + 6CO2 ----------> C6H12O6+ 6O2
Frying a hamburger represents a chemical change. The reason for this is that the heat alters the chemical nature of the meat, turning some of it into charred or denatured protein, etc. It it is heated to a high enough temperature, some of the ingredients in the meat may even turn into carbon dioxide and water, a combustion reaction of organic molecules.
Bankruptcy court records are public records, unless the court has impounded some or all the information for some good reason. There are banking publications, like Banker & Tradesman, that publish all filings in their area. Some local newspapers still publish bankruptcy filings from their communities. And you can check out the bankruptcy filings at the bankruptcy court for your area. There is usually a public access computer in the clerk's office where you can look…
The reaction of two or more elements together results in the formation of a chemical bond between atoms and the formation of a chemical compound (see our Chemical Bonding module). But why do chemicals react together? The reason has to do with the participating atoms' electron configurations (see our The Periodic Table of Elements module).
There is more than one reason why a precipitate can form. A chemical reaction that involves dissolved chemicals can produce a product that is not soluble, or is not as soluble as the reactants were. Or, even if you have a soluble chemical, if the concentration is too high, or if the temperature drops, you can still get a precipitation.
It is a chemical change since the bacteria chemically reacts with the food and forms other compounds which are not healthy for edification. There is a change in odor and sometimes even color. Another reason it is considered a chemical reaction is because it cannot be reversed back into the original fresh (not ruined) food.
The reason radioactive isotopes can be followed through the steps of a chemical reaction or industrial process is that they?
When a soda bottle is opened there is a evolution of gas Does a chemical reaction take place on opening the soda bottle Give reason for your answer?
Atom in the ground state is stable but atom in excited state is not stable the main reason for this is their energies.Atoms in excited state has more energy so they undergo chemical reaction so they are not stable but atoms in ground state has less energy than the excited state so they dont undergo chemical reaction.
You can't glue together a divided pear,if you want it to be valuable but it is not a chemical change..why?-The reason is that a chemical change is followed by entirely new product and what you have done is to seperate the pear molecules,it is still a pear!,and it is a physical change,and you are free to ask more question,because I understand that a pear has life..
One of the main differences between a physical and chemical change is that in the latter heat is given off In frying an egg, heat is also accompanied, hence, it is a chemical change. Moreover, in chemical changes a new substance is formed as a new one is formed when an egg is fried. Chemical changes are usually irreversible; the fried egg cannot be reversed to its initial state and one of the prominent features…
