Can you add more context to your question i’m confused
Answer:
C
Explanation:
Potassium metal reacts very rapidly with water, which forms Potassium hydroxide (KOH) and hydrogen gas (H2).
The problem above is simply a conversion problem. We only need a conversion factor to convert the units from amu to kg. From a conversion table, we will see that 1 amu is equal to 1.66x10^-27 kg. We convert as follows:
0.13261 amu ( <span>1.66 × 10^-27 kg / 1 amu ) = 2.20x10^-28 kg </span>
NaCl is an ionic bond:-
Na+Cl-
So, the overall charge would be zero since an ionic bond is the opposite attraction of ions.
Answer: Zero
