If its sodium it would have 11 electrons
Cans aren't entirely made of tin because of rusting. When scratched(which happens quite frequently to cans) the tin is in more danger of rusting. This is why the cans are coated in a layer of tin rather than the whole can is made of it.
It knows that when water evaporates, it carries heat energy away with it.
So your body puts some water out on your skin, and hopes that it will
evaporate. We call that "perspiring" or "sweating".
Answer:
See explanation
Explanation:
Calcium is divalent. This means that it donates two electrons during ionic bond formation. Since chlorine atom can only accept one electron during ionic bond formation, two chlorine atoms must accept the two electrons donated by calcium.
For this purpose, each time CaCl2 is formed, there must be two chlorine atoms for each calcium atom.
Answer : The balanced reaction in acidic solution is,
Explanation :
The given partial equation is,
First we have to separate into half reaction. The two half reactions are:
Now we have to balance the half reactions in acidic medium, we get:
............(1)
............(2)
Now we have to balance the electrons of the half reactions. When we are multiplying the equation (1) by 2, we get
...........(3)
Now we have to add both the half reactions (2) and (3), we get the final balanced chemical reaction.
