If 4.66 moles of hcl reacts with excess mg(oh)2 how many moles of mgcl2 will be produced? (show work , you! )

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

beta decay is the answer

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
