Can somewhere show me the dimensional analysis of this?
natita [175]

245 mm Hg = 32.6634 kPa

<u>Explanation:</u>

When the pressure inside the can is measured in mm Hg and it is needed to convert mm mercury (Hg) to kilo pascal, we have to multiply the pressure in mm Hg with  0.13332, so that the pressure is converted in kilo pascals.

1 mm Hg × 0.13332 = 1 kPa

245 mm Hg × 0.13332 = 32.6634 kPa

So the pressure in mm mercury is converted into kilo pascals.

Of the metals pb hg na and mg which will not spontaneously donate electrons to copper in solution
marta [7]

Answer : Hg (Mercury)


Explanation : In the given series of elements Na falls after the Cu in the reactivity series, for Pb it also falls after Cu, and for Mg it is the same.


Only Hg which is mercury can spontaneously donate its electrons to copper in the solution because it falls before Cu in the reactivity/activity series.
