L 8.3.2 Test (CST): Chemical Reactions Question 8 of 20
Which two chemical equations model double-replacement reactions?
A. HC2H302 + LiOH → LiC2H302 + H20
B. CH4 + 202 - 2H2O + CO2
O C. AgNO3 + LICI – AgCl + LINO3
D. 2Na+ MgCl2 – 2NaCl + Mg

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

the answer is 75.0%.
