- Arrange the following as per the instructions given in the brackets (a) Carbon, Fluorine, Beryllium (decreasing order of atomic size) (b) Sulphuric acid, Phosphoric acid, Acetic acid (increasing order of number of replaceable H atoms per molecule) (c) Potassium, Lithium, Sodium (increasing order of ionization potential)
- according to adsorption theory of catalysis, the speed of reaction increase because
- find odd man out:gold ,silver,iron, diamond
- Hi, sir/madam could you please help me to find answer for this question which is the most metallic element and which element having highest atomic radius
- GIVE REASON Electronegativity increases across a period from left to right in the periodic table.Pls let me know-thanks.
