What type of chemical reaction is this? for the magnesium oxide with sodium chloride to produce magnesium chloride and sodium oxide

OpenStudy (abb0t):

Write it down, there's only about 5 types of chemical reactions.

OpenStudy (anonymous):

Mgo+NacI>MgCI2+Na2C

OpenStudy (joannablackwelder):

MgO+NaCI>MgCI2+Na2O This is the unbalanced reaction.

OpenStudy (joannablackwelder):

Let's see. The main types of reactions are synthesis, decomposition, single replacement, double replacement, and combustion. Do you know what these terms mean?

OpenStudy (anonymous):

not really. I'm trying to understand it .

OpenStudy (joannablackwelder):

Ok. Do you first understand the unbalanced reaction, the way that I wrote it?

OpenStudy (joannablackwelder):

Synthesis is two (or more) elements or compounds forming one compound. A + B -> AB

OpenStudy (joannablackwelder):

Decomposition is one compound decomposing into multiple compounds or elements. AB -> A + B

OpenStudy (joannablackwelder):

Single replacement is when an element replaces or is substituted for one of the elements in a compound. A + BC -> AB + C

OpenStudy (joannablackwelder):

Double replacement is basically an exchange of partners. AB + CD -> AD + BC

OpenStudy (anonymous):

ok the balance would be Mgo+ 2NacI=MgI2+Na2O

OpenStudy (joannablackwelder):

I think you mean MgO+ 2NaCI=MgCI2+Na2O which is perfect! :)

OpenStudy (joannablackwelder):

A combustion reaction is when oxygen combines with another compound to form water and carbon dioxide.

OpenStudy (anonymous):

You right and I believe would be double replacement

OpenStudy (joannablackwelder):

Awesome! That is what I get. :)

OpenStudy (anonymous):

THANK YOU SO MUCH ,YOU ARE AWESOME

OpenStudy (joannablackwelder):

Glad I could help :)
