`2KI+I_2+22HHNO_3to2HIO_3+2KIO_3+22NO_2+10H_2O`
If 3 mole of KI and 2 moles `I_2` are reacted with excess of `HNO_3`.Volume of `NO_2` gas evolved at STP is :

2KI+I_(2)+22HNO_(3)rarr2HIO_(3)+2KIO_(3)+22NO_(2)+10H_(2)O If 3 mole of KI & 2 moles I_(2) are reacted with excess of HNO_(3) . Volume of NO_(2) gas evolved at NTP is : 2KI+I_(2)+22HNO_(3)rarr2HIO_(3)+2KIO_(3)+22NO_(2)+10H_(2)O

2KI+I_(2)+22HNO_(3)rarr2HIO_(3)+2KIO_(3)+22NO_(2)+10H_(2)O If 3 mole of KI & 2 moles I_(2) are reacted with excess of HNO_(3) . Volume of NO_(2) gas evolved at NTP is : 2KI+I_(2)+22HNO_(3)rarr2HIO_(3)+2KIO_(3)+22NO_(2)+10H_(2)O

KI+I_(2)+HNO_(3) to HIO_(3)+KIO_(3)+NO_(2) If 3 moles of KI and 2 moles of I_(2) are mixed with excess HNO_(3) then volume of NO_(2) gas evolved at NTP is:

When PbO_2 reacts with cone HNO_3 , the gas (es ) evolved is//are .

When PbO_2 reacts with cone HNO_3 , ………………… gas is evolved .

When Pb O_(2) reacts with concentrated HNO_(3) , the gas evolved is
