The balanced reaction is:<span>
Mg (s) + 2HCl (aq)
--> MgCl 2 (aq) + H 2 (g)
We
are given the amount hydrochloric acid to be used for the reaction. This will
be the starting point of the calculation.
40.0 g
HCl ( 1 mol HCl / 36.46 g HCl)
(1 mol H2 / 2 mol HCl) (2.02 g H2 / 1 mol H2) = 1.11 g H2</span>
Answer:
164.088 g/mol
Explanation: hope this helps
Rate, fast :Maybe these are the answers.
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side
A chemical symbol is a notation of one or two letters representing a chemical element
A chemical formula identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element.
It is impossible to narrow down anything about the unknown.
Flame tests are common analytical techniques used to determine the composition of an unknown compound based on the color that it imparts to flame. Each metal ion imparts a specific color to flame which helps us to identify it.
In this case, two colors were visible in the flame and it will be difficult to determine which of the colors corresponds to the actual metal ion present.
Therefore, it is impossible to narrow down anything about the unknown.
