The organism could live in the cave, eat the ant, and drink from the lake.
Melting (solid to liquid)

Now, balance the equation:


in gaseous state exist as a diatomic molecule.
When a chemical reaction takes place it changes the composition of the reactants. The ways to tell if a reaction is occurring are,
1-Release of heat
2-Production of a gas
3-Formation of a precipitate
4-Change in color
From the equation,
4 mole of lithium produces 2 mole of lithium oxide
4.37 mol of lithium produces (4.37÷4)x2 mol of lithium oxide
