What would cause the percent yield of reaction to be less than 100%

The cause of percent yield of reaction to be less than 100% are:

1. incomplete or competing reactions

2.  loss of sample during recovery

Explanation:

a sequence is a function whose domain is the set of natural numbers.

natural numbers are all the negative and positive integers

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
