Ca₃P₂ + H₂O → (P) + Ca(OH)₂
moist KI + O₃ → (Q) + ...
H₂O₂ + Ag₂O → (R) + ...
Which of the following options is/are CORRECT regarding P, Q and R?
Options:(select one or more)
Answer:
A, B, C
Solution:
P = PH₃ (inflammable - used with C₂H₂ in Holme's signals, so (A) true, (D) false); Q = I₂ (2KI + O₃ + H₂O → I₂ + 2KOH + O₂), turns starch blue; R = O₂ (H₂O₂ + Ag₂O → 2Ag + H₂O + O₂), paramagnetic.
