Explanation:
Hello there!
In this case, according the given balanced chemical reaction:
It is possible to evidence the 1:1 mole ratio of hydrogen (molar mass = 2.02 g/mol) to zinc (atomic mass = 65.41 g/mol) which is used to calculate the grams of the latter needed for the production of 5 grams of the former via stoichiometry:
Best regards!
Answer:
If one is standing in flowing water and thicker liquid, it will be easier to resist the force of the thicker liquid in comparison to water .
It is so because the thicker liquid has an internal resistance that acts when the liquid is in motion, and it is easy to oppose the motion of thicker liquid while water do not have internal resistance and it become harder to resist teh force.
The balanced chemical equation for the reaction is as follows
Mg(OH)₂ + 2HCl ---> MgCl₂ + 2H₂O
molar ratio of HCl to MgCl₂ is 2:1
There's excess Mg(OH)₂ therefore HCl is the limiting reactant.
the amount of product formed is determined by the amount of limiting reactant present
so when 2 mol of HCl reacts - 1 mol of MgCl₂ is produced
therefore when 4.66 mol of HCl reacts - 1/2 x 4.66 = 2.33 mol of MgCl₂ is produced
answer is 2.33 mol of MgCl₂
