A. The correctly balanced equation is that in which the number of atoms of a certain element at the left-hand side is similar to that in the right hand side or the reactant side and product side, respectively. From the given equation, the answer would be,

       C. Cl2 + 2NaI --> 2NaCl + I2


B. In the given chemical reaction above, heat is emitted such that it appears in the product side of the equation. Hence, this is an example of a combustion reaction. 

C. Similar with the reasoning in letter A, the answer to this item is,
          B. 2H2 + O2 --> 2H2O

) is it possible for one component of a vector to be zero, while the vector itself is not zero?
Natalka [10]
The least number of component of a vector quantity is two. These are the x-component and the y-component. 

The resultant vector, or vector as we refer to it in this item, can be calculated through the equation,
              RV = sqrt ((Vx)² + (Vy)²)

From the equation, it can be noted that if we let Vx equal to zero,
              RV = Vy

Similarly, if we let Vy be equal to zero then,
             RV = Vx

Thus, it is still possible for the vector to become nonzero even if one of its components is zero.
