3 0
Moles of Ca(OH) _{2} = 6.5 mol
mole ratio of <span>Ca(OH) _{2} : HCl =  1 : 2
     </span>∴ since <span>Ca(OH) _{2} cntain 6.5 mol, then HCL contains (2 * 6.5) mol
       Thus moles of HCl = 13.0 </span><span>mol
   Volume of HCl needed = </span>\frac{moles}{molar concentration}
                                        = \frac{13.0 mol}{1.5 mol / dm^{3} }<span> 
</span><span>                                        =  8.67 </span>dm^{3}
since  dm^{3}  =  L
<span>then volume of HCL needed = 8.67 L
 </span>

Passive prostheses are:
Len [333]

Passive prostheses are self-regulating, as shown in the first answer option.

We can arrive at this answer because:

  • Passive prostheses are devices used to replace parts of the body that were lost by an incident.
  • These prostheses are very useful to establish balance or the aesthetics of the body, but they have no articulations and no movement mechanism, being static.

This limitation allows passive prostheses not to need external regulation and to be self-regulated by fitting the body parts.

You can find more information about articulations and their effects on the link:
