Pokémon is it that's the anwser

4 mole Na = 2 mole Cl2
Answer:
Synthesis
Explanation:
Chemical equation:
3S + 2Fe → Fe₂S₃
The solid iron react with solid sulfur and form iron(III) sulfide. The reaction type is synthesis because,
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
A + B → AB
Other options are incorrect because,
In double displacement two compound exchange their ions and form new compounds.
AB + CD → AC +BD
In decomposition one reactant is break down into two or more product.
AB → A + B
In single replacement one elements replace the other element in compound.
AB + C → AC + B
Answer:
The mouth uses both mechanical and chemical digestion. Mechanical digestion involves physically breaking down the food into smaller pieces (using the jaw/teeth). However, chemical digestion then takes over and starts breaking down the food into simpler nutrients that can be used by the cells using saliva, which is naturally made within the mouth.
Hope this helps you! Have a great day! :D
