The answer to your question is DNA!!!!! :)
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
The chemical reaction is balanced.
Explanation:
We have the following chemical reaction:
NaOH + HCl → NaCl + H₂O
It is a neutralization reaction between a base and an acid which produce a salt and water.
To balance the chemical reaction the number and type of atoms entering the reaction have to be equal to the number and type of atoms leaving the reaction. We do that to conserve the mass.
We do not need to add other stoechiometric coefficients because the reaction is already balanced.
1 Na atom is entering the reaction and 1 Na atom is leaving the reaction
1 Cl atom is entering the reaction and 1 Cl is leaving the reaction
1 O atom is entering the reaction and 1 O atom is leaving the reaction
2 H atoms are entering the reaction and 2 H atoms are leaving the reaction
