Table describes the properties of four compounds. (table attached) compounds are most likely ionic?

compounds A and B
compounds b and c
compounds c and d
compounds d and a​

the dissolution of polymer can be thermodynamically described in 2 steps.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
