Answer:
Double replacement reaction, Al(OH)3 + Na3(NO3)
Step-by-step explanation:
1) We can see that there are 2 compounds that contain 2 elements. This means we have a double replacement reaction.
2) Make the products
Take the elements on the outside of the equation
Al+3 and (OH)-1
criss cross the charges and you get
Al(OH)3
Now do the same with the remaining elements
Na+1 (NO3)-3
Na3(NO3)
Al(OH)3 + Na3(NO3)
