Provided a balanced equation with variables (X & Y) instead of actual elements. Determine the charge of the variable X and Y? 4X + 3Y, → 2X Y3
X is +1 and Yis-2
Xis +2 and Yis-2
Xis +3 and Yis-2
X is +2 and Yis-3

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

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
