Which statement is true about the properties of the majority of the elements in the far left column of the periodic table? A.
They have low heat conductivity.
B.
They have low electrical conductivity.
C.
They are highly reactive.
D.
They have no luster.

C: They are highly reactive

Explanation:

The elements on the left side of the table are mostly metals except for hydrogen. And most metals are highly reactive.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
