Assuming that the experiment started
with the magnesium and did not combine with oxygen, this extra mass would actually
decrease the amount of oxygen. This is because it only artificially increases
the original mass. Therefore this actually increases the error.

chemical A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion
examples flammability, toxicity, acidity, reactivity
pretty much the difference is is that chemical changes its chemical reaction involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance Physical change does not do that
Answer:
HBr(aq) + LiOH(aq) = LiBr(aq) + H2O(l)
Explanation:
For this reaction, the reactants are the hydrobomic acid and the lithium hydroxide which produces the products lithium bromide and water.
Answer: Zirconium [Kr]4d :)
Explanation:
Because of the fact that NaBr is an ionic bond, the bond is harder to break, therefore it needs more heat (or a higher temperature) to break it.
