Assertion: Helium shows only positive deviations from ideal behaviour. Reason: Helium is an inert gas.
Why are zero group elements chemically inert ?
Why is SF_(6) kinetically inert ?
Liquid Helium is called superfuluid. Why ?
What is the total number of unpaired eletrons in inert gas ?
To an equilibrium mixture of 2SO_(2) (g) + O_(2) (g) hArr 2 SO_(3) (g) some helium , an inert gas, is added at constant volume. The addition of helium causes the total pressure to double . Which of the following is true ?
Why does helium exist as He whereas hydrogen exists as H_2
N_(2), CO, CN^(-) and NO^(+) are isoelectronic but the former is chemically inert and latter three are very reactive, why ?
a. Why are alkanes inert ? b. Why the (C----C) bond rather than (C----H) bond breaks when alkanes are pyrolysed ? c. Why the combustion of alkanes does not occur at moderate temperature, although it is an exothermic process ?
