Four properties of water are listed. It has high thermal conductivity.
It reacts with metals to form metal hydroxide and hydrogen gas.
When heated to 100 °C, water evaporates.
It decomposes to form hydrogen and oxygen.

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.
