write Balanced equation for copper metal and oxygen gas and acetic acid react to form water and copper 2 acetate?
The correct answer and explanation is:
The reaction between copper metal (Cu), oxygen gas (O₂), and acetic acid (CH₃COOH) to form copper(II) acetate (Cu(CH₃COO)₂) and water (H₂O) can be written as:
Balanced Equation:
2Cu(s)+O2(g)+4CH3COOH(aq)→2Cu(CH3COO)2(aq)+2H2O(l)2Cu (s) + O_2 (g) + 4CH_3COOH (aq) \rightarrow 2Cu(CH_3COO)_2 (aq) + 2H_2O (l)
Explanation:
In this reaction, copper metal reacts with oxygen gas in the presence of acetic acid to form copper(II) acetate and water. The reaction is a type of double displacement reaction, where the copper ions (Cu²⁺) from the copper metal react with the acetate ions (CH₃COO⁻) from acetic acid. This forms copper(II) acetate (Cu(CH₃COO)₂), which is a soluble salt, and water is formed as a byproduct.
- Copper and Oxygen Reaction: Copper (Cu) interacts with oxygen (O₂) to form copper(II) ions (Cu²⁺), which is essential for the formation of copper(II) acetate.
- Acetic Acid as a Reactant: Acetic acid (CH₃COOH) provides the acetate ions (CH₃COO⁻) that react with the copper(II) ions (Cu²⁺) to form copper(II) acetate (Cu(CH₃COO)₂).
- Formation of Copper(II) Acetate: Copper(II) acetate is an ionic compound consisting of copper ions (Cu²⁺) paired with acetate ions (CH₃COO⁻). It is soluble in water and can be obtained as a product in this reaction.
- Water Production: The reaction also produces water as a byproduct, which results from the combination of hydrogen (H) from acetic acid with oxygen (O) from the oxygen gas (O₂).
- Stoichiometry: In balancing the reaction, it is important to ensure the number of atoms for each element is conserved on both sides of the equation. For this particular reaction, two copper atoms, four acetic acid molecules, and one molecule of oxygen gas are required to balance the products, which are copper(II) acetate and water.
The reaction is a synthesis process that highlights the combination of elemental copper, oxygen, and acetic acid to produce copper(II) acetate and water.
