The answer to your question is Single replacement
Explanation:
Types of reaction in Chemistry
Synthesis two or more reactants combine to produce one single product
Decomposition one reactant splits producing two or more products
Single replacement One element replaces a similar one in a compound.
Double replacement Two compounds interchange their cations and anions.
Combustion one compound reacts with oxygen to produce carbon dioxide and water.
Reaction given
Fe⁺² + CuSO₄ ⇒ Cu + FeSO₄
This is a single replacement reaction
Answer:
Mw = 179.845 g/mol
Explanation:
∴ w = 26.2 g
∴ 1 mol = 6.02 E23 molecules.......Avogadro's number
⇒N° moles = 8.77 E22 molecules * ( mol / 6.02 E23 molecules ) = 0.146 mol
⇒ Mw = 26.2 g / 0.146 mol = 179.845 g/mol
