Answer 1

Ответ:

Oxides are chemical compounds with one or more oxygen atoms combined with another element (e.g. Li2O). Oxides are binary compounds of oxygen with another element, e.g., CO2, SO2, CaO, CO, ZnO, BaO2, H2O, etc. These are termed as oxides because here, oxygen is in combination with only one element

Объяснение:

Answer 2

1. The correct answer is b) Anamorphic. Anamorphic is not a term used to describe oxides.

2. Relationship chain for metals: Metal -> Element -> Compound -> Ore -> Extraction

3. Reaction between acids and bases is called "Neutralization."

4. The options provided (a) Single displacement, and (b) Oxidation are not directly related to the reaction between acids and bases.

5. Classify the oxides into four groups: a) Basic Oxides: MgO, K2O, BeO b) Acidic Oxides: SO2, Cl2O7, I2O5 c) Amphoteric Oxides: Cr2O3, Al2O3 (not listed, but it's an example) d) Neutral Oxides: N2O, CO

6. Acidic oxides are called "acidic" because they can react with water to form an acid. For example, when sulfur dioxide (SO2) dissolves in water, it forms sulfurous acid (H2SO3). These oxides can also react with bases to form salts and water. Their ability to produce acidic solutions is why they are termed "acidic."

7. Relationship chain for nonmetals: Nonmetal -> Element -> Compound -> Covalent Compound -> Diatomic Molecule
