El hierro en estado natural es oxidado por oxigeno de fierro.¿ si usted tiene 35 moles de hierro y los mezcla con 200 litros de oxigeno cuantos moles de oxido de fierro puedo formar? fe + o2---> fe2o3

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

c is the answer because when something is left after something evaporates that shows the chemical change.

1 a

2 d

3 a

4 c
