Which of the following statements `is//are` wrongs?
The following reactions occur:

Options

A. `P_(4)` is the limiting quantity
B. `O_(2)` is the limiting quantity
C. mass of `P_(4) O_(10)` obtained is `2.2 g`
D. Mass ov `P_(4) O_(6)` obtained is `2.84 g`

Answer

B, C, D

Explanation

`n_(P_(4)) = (1.24)/(31 xx 4) = 0.01 "mol", n_(O_(2)) = (8)/(32) = 0.25` moles
In reaction (i), moles of `O_(2)` required
`= (0.01 "mol" P_(4)) ((5 "mol" O_(2))/("mol" P_(4)))`
`= 0.01 xx 5 = "mol"`
Since there is more `O_(2)` present than required
a. Therefore, `P_(4)` is the limiting quantity.
Wrong.
`[Mw P_(4) O_(10) = 284]`
0.01 mol of `P_(4)` produces = 0.01 mol of `P_(4) O_(10)`
`= (0.010 "mol" P_(4)) ((1 "mol" P_(4) O_(10))/("mol" P_(4) O_(10))) ((284 g P_(4) O_(10))/("mol" P_(4) O_(10)))`
`= 0.01 xx 284 = 2.84 g`
Hence, (c ) is wrong
d. `[Mw "of" P_(4)O_(6) = 220]`
Weight of `P_(4) O_(6)` produced
`= (0.01 "mol" P_(4)) ((1 "mol" P_(4) O_(6))/("mol" P_(4) O_(6)))((220 g P_(4) O_(6))/("mol" P_(4)O_(6)))`
Hence, (d) is wrong
