What does nabr + ca(oh)2 -> cabr2 + naoh create? is it a physical or chemical or physical? for an example for what does it create: like rust

The given reaction is a chemical change and equation for rust is given below.

Explanation:

A chemical change is defined as the change where a change in the chemical composition takes place and results in the formation of a new substance. These reactions are usually an irreversible reaction.

A physical change is defined as the change in the shape and size of a substance. No change in the composition of a substance takes place as no new substance is formed. These reactions are usually reversible reaction.

For the given reaction:

The given reaction is a chemical change because new substances are being formed. This is an example of double displacement reaction because exchange of ions is taking place.

The formation of rust is also a chemical change because a reddish-brown coating on iron metal is being formed which is the rust. The equation for the following chemical change is:

the answer is d : ) have a good da

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.
