What occurs when potassium reacts with bromine to form potassium bromide? 1) Electrons are shared and the bonding is ionic.

2) Electrons are shared and the bonding is covalent.

3) Electrons are transferred and the bonding is ionic

4) Electrons are transferred and the bonding is covalent.

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
