Explanation:
Potassium and Sodium are both metals on the periodic table. Both elements are found on the s-block of the table. Therefore, it is not possible for both of them to combine to form a compound.
For a compound to form two elements must combine in a definite order to given single product.
The combination is facilitated by a loss, gain or sharing of electrons between two species. This leads to an attraction between the combining species.
Both Sodium and potassium would prefer to lose electrons and there is no reason for them to combine to form a compound.
Answer:
The answer is 42, 39 grams of LiCl
Explanation:
We calculate the weight of 1 mol of LiCl, from the atomic weights of each element obtained from the periodic table:
Weight 1 mol LiCl= Weight Li + Weight Cl =6,94 g+ 35, 45 g= 42, 39grams
The correct answer would be C. Convection, which describes that heat rises.
