What substance in the air could reacted with magnesium during burning?

When magnesium burns, it reacts primarily with oxygen in the air. The reaction produces magnesium oxide, a bright white flame, and intense heat. This reaction is highly exothermic, releasing a significant amount of energy as magnesium combines with oxygen.


What is the independent variable in the magnesium oxide reaction?

The independent variable in the Magnesium Oxide Lab would be the Mass of the Magnesium Ribbon. This is because the mass of the product, i.e. Magnesium Oxide, depends on how much Magnesium is added.


Can good scientific analysis can overcome poorly collected evidence?

In certain cases in could but in a general term no it cannot, poorly collected evidence could contaminate it or even if obtained wrong could be thrown out and not be used as evidence that is why there are procedures to be followed.


The burning magnesium becomes uncontrolled oops how will this procedural error affect the reported mole ratio of nagnesium to oxygen in the analysis?

You will end up having less oxygen because it goes in doubles, and it is considered as flammable, and magnesium wouldn't burn if you didn't trap oxygen inside the magnesium foil. Some of the Magnesium WILL boil away as it burns, but you will end up with less oxidation anyway.


What evidence is there to indicate that the Epsom salts and ammonia reacted?

Evidence of the reaction between Epsom salts (magnesium sulfate) and ammonia would include observing the formation of a white precipitate (magnesium hydroxide) and the release of ammonia gas, which has a distinct pungent smell. Additionally, one could measure the change in pH, which would increase as the ammonia reacts with the magnesium sulfate to form magnesium hydroxide.


What precautions should be taken when burning magnesium?

Magnesium ribbon is not particularly dangerous unless you ignite it. If it does catch fire, it will burn with an intensly bright white light that will burn your retinas if you aren't wearing appropriate eye protection or aren't looking away while it is burning. It is as bad as watching arc welding because of the ultraviolet light emitted. It is good form to wear eye protection in the lab at all times. While you can tear the ribbon with your fingers, it is possible that it could poke you in the eye and scratch your cornea.


What is antidotal evidence?

A grammatical mistake. It is meant to say "anecdotal evidence" which is evidence that may be true but could be unreliable and may or may not lead to the desired conclusion. It is as opposed to "scientific evidence" which may be held as reliable.


Can you use lycopodium for treatment of hernia?

I guess you could. However, there is no scientific evidence that it is effective in treating hernias.


What did William Crookes conclude from his experiment?

Priestley and Lavoisier discovered oxygen. I think they burned magnesium and it got heavier. The phlogiston theory (the theory that people believed about burning and combustion) could not answer this so they had discovered something. We now know that oxygen from the air is "extracted" when the magnesium is burned. the oxygen then combines with the magnesium and form magnesium oxide. So if you started with 24g of magnesium and burned it, you would end up with about 40g of magnesium oxide.


Could people be werewolves?

Werewolves are mythical creatures and no scientific evidence has ever been found that one exists.


Could a scientific knowledge be changed or modified?

yes because theories are always changed when found new evidence
