There are multiple factors that contribute to the cost of a mineral. First of all is the demand or application, which will be related to its physical properties. For example, nontarnishing metals like gold are held in high value for their appearance. Second is the supply of the mineral, those that only have a small quantity in the earth's crust are likely to be more expensive. Third is the cost of extraction and manufacturing. Some minerals may be abundantly found, but may be distributed over a wide area, meaning that it is still expensive to mine and transport.

Ivanshal [37]

Answer:

$HCl conc=2.2M$

Explanation:

From the question we are told that:

Mass of zinc $Mass_{z_n}=2.5g$

Initial conc of HCl $HConc_1=6.0M$

Initial volume of HCl $Hvol_1=20.0mL$

Molar mass of zinc $M_{Z_n}=65.38g/mol$

Generally the equation for reaction is mathematically given by

$2HCL+Zn\implies ZnCl_2 +H_2$

Generally the equation for moles of zinc $m_{z_n}$ is mathematically given by

$m_{z_n}=\frac{Mass_{Z_n}}{M_{Z_n}}$

$m_{z_n}=\frac{2.5g}{M_{65.38}}$

$m_{z_n}=0.038molZn$

Generally the equation for moles of $m_{HCl}$ is mathematically given by

$m_{HCl}=HConc_1*Hvol_1$

$m_{HCl}=6.0M*20.0mL$

$m_{HCl}=6.0M*20.0*10^{-3}L$

$m_{HCl}=0.12\ mol\ HCl$

Generally the reacted moles of HCl $HCl_[reacted]$ is mathematically given by

Since

Zn:HCl =1:2

Therefore

$HCl_[reacted]=0.038*\frac{2}{1}$

$HCl_[reacted]=0.076mol \ HCl$

Generally the moles of HCl after Zn oxidization X is mathematically given by

$x=0.12-0.076$

$x=0.044 mol HCl$

Generally the conc of hydrochloride acid X is mathematically given by

$X=\frac{0.044}{0.020}$

$X=2.2 M Hcl$

Therefore Conc of HCl

$HCl conc=2.2M$
