Given the balanced equation representing a reaction:Al2(SO4)3 +6NaOH ==> 2Al(OH)3 + 3Na2SO4

The mole ratio of NaOH to Al(OH)3 is

(1) 1:1 (2) 3:1

(3) 1:3 (4) 3:7

Answers

The answer is number 2. 3:1. This is the simplified value of 6:2 which came from 6NaOH:2Al(OH)3. The original ratio is 6:2 but it can be simplified through dividing it each by 2. So 6 divided by 2 equals to 3 and 2 divided by 2 is 1. Therefore the simplified ratio is 3:1.

How does a magnet separate mixtures?

Answers

It can only do that when  one of the components of the mixture is a magnetic
material.

When you have that situation, you pass the magnet over the mixture ... shaking
the mixture if it's a dry mixture of powders or pieces ... and the magnetic part of
the mixture moves toward the magnet, while the nonmagnetic parts of the mixture
couldn't care less about the magnet and they just stay where they are.
It will separate when one of the elements found in the mixture is magnetic. This process can't be done in a compound as a compound is chemically bonded!
