Moles of Bromine produced = 9 moles
<h3>Further explanation</h3>
Given
9 moles of Chlorine gas
Word equation
Required
Moles of Chlorine produced
Solution
We change the word equation into a chemical equation (with a formula)
Aluminum bromide reacts with chlorine gas to produce Aluminum chloride and bromide gas
2AlBr₃+3Cl₂⇒2AlCl₃+3Br₂
moles Cl₂ = 9
Maybe you mean, <em>how many moles of Bromine can we produce?</em>
From equation, mol ratio Cl₂ : Br₂ = 3 : 3, so mol Br₂=mol Cl₂=9 moles
Explanation:
A cup of mixtures of iron fillings, sand and salt is a mixture who constituents are in the same phase i.e solid.
To separate them out we use the physical properties of the substances.
- First spread out the mixture uniformly over a piece of paper or on the table.
- Pass a bar magnet over it.
- The iron fillings will become attracted to the magnet and separate from the mixture.
- then pour water into the mixture of sand and salt
- the salt will dissolve since sand is made up of quartz which are highly insoluble.
- separate the water solution. Evaporate to dryness and recover the salt.
- the sand is left behind and dried.
