Can somewhere show me the dimensional analysis of this?

natita [175]

245 mm Hg = 32.6634 kPa

Explanation:

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.

When barium reacts with tellurium to form an ionic compound, each metal atom loses electron(s) and each nonmetal atom gains elec

Bess [88]

Answer: The ionic compound formed is $baF_2$ (barium fluoride)

Explanation:

Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.

Taking the metal as barium and non-metal as fluorine.

Barium is the 56th element of the periodic table having electronic configuration of $[Xe]6s^2$

This element will loose 2 electrons and will form $Ba^{2+}$ ion

Fluorine is the 9th element of the periodic table having electronic configuration of $[He]2s^22p^5$

This element will gain 1 electron and will form $F^{-}$ ion

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

Hence, the ionic compound formed is $baF_2$ (barium fluoride)
