2 Li(s) +Cl₂→ 2 Li⁺ (aq) + 2Cl⁻ (aq)
The cell potential of the reaction above is +4.40V
<em><u>calculation</u></em>
Cell potential =∈° red - ∈° oxidation
in reaction above Li is oxidized from oxidation state 0 to +1 therefore the∈° oxid = -3.04
Cl is reduce from oxidation state 0 to -1 therefore the ∈°red = +1.36 V
cell potential is therefore = +1.36 v -- 3.04 = + 4.40 V
Coffee cools more quickly in a ceramic mug than in a Styrofoam
cup.
Explanation:
Styrofoam is a good insulator, thus for keeping the coffee warm for longer, it is a good choice than ceramic. The process involved in the control of heat dissipation employs the fact that the vapours in the form of gas are entrapped within, they lessen the conduction process between the molecules as a result molecules do not collide hence no energy releases or exchange takes place.
Styrofoam cups are made up of polystyrene foam. As a result of high insulation at styrofoam body conduction is not possible so coffee is warmer for longer.
<span>Temperature causes water molecules to move more quickly, because each individual molecule has more energy as it gets hotter .
So, the answer is A.

It’s all based on you but yours could be anything hard you went through and how you overcame it. Also say how it made you the person you are today
