Answer: The balanced reaction is CCl4 → C + 4Cl
A balanced chemical equation is the one, which contains equal number of atoms corresponding to each element participating in the reaction and having same charge for the reactants and the products.
In the given reaction CCl4 → C + Cl, the number of chloride atoms are imbalanced on both sides as it is four on the reactant side while it is one on the product side.
Thus, the balanced reaction for this is-
CCl4 → C + 4Cl

Answer:
white for the first one and brown for the secound one
Explanation:
The first law of thermodynamics states that heat is a form of energy and thermodynamics processes are therefore subject to the principles of conservation of energy. The principle of conservation of energy on the other hand states that energy can neither be created nor destroyed, it can only be changed from one form to another.
The mathematical equation for the first law of thermodynamic states that
E = Q - W,
Where E = change in internal energy
Q = Heat added to the system and
W = Work done by the system.
This equation shows that, energy is conserved in the system, that is, the change internal energy of a system is a function of the heat added to the system minus the work done by the system. Thus, all the energy supply to the system has been accounted for and nothing is lost; this is in agreement with the principle of conservation of energy.
