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

$HCl conc=2.2M$

Which property of water makes it helpful to use in car radiators?

Nezavi [6.7K]

The correct answer is<span> C) Water takes long to heat and cool down than other liquids.

It doesn't climb up the sides of a tube any more than other solutions do, and being a universal solvent has nothing to do with radiators. It does however take a long time to heat and cool down since you don't have a 100+ celsius burner to heat it up in an instant.</span>

Please help I need the answer by today and it is very important! Which of the following statements best describes why the mass o

Juliette [100K]

D, because matter does not change in space but unlike gravity, which changes, matter, is the mass of it, which will stay the same unless there is a chemical change or, physical change, but not in this case, so the answer you are looking for is D. hope this enlarged your understanding and knowledge.
