Cathode is where reduction (gain of electrons) takes place in both electrolytic and galvanic cells. Anode is where oxidation occurs. Mnemonic: RED CAT (Reduction at Cathode), AN OX (Oxidation at Anode).
Explanation:
Aldehydes are organic compounds containing the formyl group, -CHO, where a carbon atom is double-bonded to an oxygen atom and single-bonded to a hydrogen atom. -OH is the hydroxyl group (alcohols), -COOH is the carboxyl group (carboxylic acids), and -CO- is the carbonyl group (ketones).
Explanation:
Antoine Lavoisier is known as the father of modern chemistry and formulated the law of conservation of mass—mass is neither created nor destroyed in a chemical reaction. Dalton's atomic theory supported this law. Thomson discovered electron. Rutherford discovered nucleus. Lavoisier also named oxygen and hydrogen and established the role of oxygen in combustion.
Explanation:
A decomposition reaction is one where a single compound breaks down into two or more simpler substances. Heating potassium chlorate (KClO₃) breaks it down into potassium chloride and oxygen gas. A is combination, C is displacement, and D is double displacement.
