Stability of the species `Li_(2), Li_(2)^(-), Li_(2)^(+)` increases in the order of

Stability of the species Li_(2), Li_(2)^(-) and Li_(2)^(+) increases in the order of

Li^(+),Mg^(2+),K^(+),Al^(3+) (Arrange in increasing order of radii)

Li_(2)O_(2) is formed when

In the reaction 6Li+N_(2)rarr2Li_(3)N

The point (2, -3) lies in the quadrant :

Chemical absorbes can be used to remove exhaled CO_(2) of space travellers in short spce flight. Li_(2)O is one of the most efficient in terms of absorbing capacity per unit weight. If the reaction is: Li_(2)O+CO_(2)rarrLi_(2)CO_(3) , What is the absorption efficiency of pure Li_(2)O in litre CO_(2)(STP) per kg ?
