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:
tertiary; quaternary
Explanation:
The orientation of all the atoms of a protein in three dimensions represents its tertiary structure. It includes the folding of the polypeptide chains in a way that brings are far apart amino acids of its secondary structure close together. Various segments of a polypeptide chain interact to form tertiary structures and these segments are held together by different kinds of weak interactions.
However, disulfide cross-links between the segments of polypeptide chains also stabilize the tertiary structure of some proteins. Likewise, disulfide bonds also hold the protein subunits of some proteins together and thereby, contribute to the quaternary structure. For example, two light chains of an antibody are joined together by disulfide bonds.
