In this redox reaction, identify the reducing agent. 2li + f2 2lif

As what we see in the chemical reaction that is given, we can conclude that the Lithium must be the reducing agent since it is the one that is oxidised. In addition to that, a redox reaction or simply known as the oxidation-reduction reaction usually operates when electrons get transferred between species.

The density of water is 1 g/cm cubed and in order for the pebble to sink its density has to be greater than the density of water and in order for the twig to float its density has to be less than the density of water
