11. what are transition metals?
o elements that are in group 18
o elements with characteristics similar to metals, except when exposed to high heat
o elements that are poor conductors of heat and electric current
o elements that fall between those on the left and right sides of the periodic table

elements that fall between those on the left and right sides of the periodic table

Explanation:

The term 'transition metals' emphasises their position in the periodic table. The term shows that they are metals sandwiched between the left and right hand sides of the periodic table. They are found between groups IIA and IIIA. The former are s-block metals while the later are p-block metals. The transition metals all possess d-orbitals which are partially filled.

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
