PLEASE HELP
The chemical formula for a compound tells what?

A. How electrons are arranged

B. how stable the compound is

C. what elements it contains

D. what type of chemical bond it forms

All objectives are correct but C is most suitable

Explanation:

All objectives A, B, and D can be shown in bonding arrangement which is not the case for C.

For example, complex compounds like

Sodium aluminate NaAl(OH)

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
