What volume of 0.140 HCl is needed to neutralize 2.58 of Mg(OH)2 ? ...?

elena-s [515]

To make a first step you have to know the balanced form for neutralization formula: $Mg(OH)2(aq)+2HCl(aq)--\ \textgreater \ 2H2O+Mg(aq)+Cl(aq)
$
According to this, you can calculate what you are being asked : $0.0442molMg(OH)2(x)(2molHCl)/(1molMg(OH)2)=0.0885molHCl$
Then we have : $0.140MHCl=0.140(mol/L)HCl$
Hope everything is clear, here is the exact answer you need : $V=(0.0885molHCl)/(0.140(mol/L)HCl)=0.632LHCl

the process of separating a liquid/solid mixture by slowly pouring the liquid component into a new vessel as the solid settles t

olga55 [171]

The process involving separation of liquid/solid mixture as regards this question is Decantation.

Decantation can be regarded as one of the process used in separation of liquid from solid as well as other immiscible (non-mixing) liquids through the removal of the liquid layer that is present at the top from the layer of solid/liquid which present at the below.

In the process, the liquid will be poured slowly into another vessel as the pouring continues, then the solid will settle in the original vessel.
