What is isotonic elements ? |
| Answer» Two nuclides are isotones if they have the same neutron number N, but different proton number Z. For example, boron-12 and carbon-13 nuclei both contain 7 neutrons, and so are isotones . Similarly, 36S, 37Cl, 38Ar, 39K, and 40Ca nuclei are all isotones of 20 because they all contain 20 neutrons.They are called isotonic elements. | |

What is difference between resistance and resistivity?explain in long format. |
| Answer» \tResistance across a conductor is the ratio of the potential difference across it to the current flowing through it. Resistivity of a material is the ratio of electric field strength to the current density at a specific temperature.\tResistance is measured in units of ohms (Ω). Resistivity is measured in units of ohm metres (Ω m).\xa0\tResistance depends on the object’s material, temperature as well as its dimensions (directly proportional to length, inversely proportional to the cross-sectional area for the case of a uniform metal wire). Resistivity is not dependent on the dimensions. It is, however, dependent on temperature. | |

What is the difference between ethanol and ethanoic acid |
| Answer» \tEthanol: Ethanol is a monohydric alcohol with a sweet smell which boils at 78.5°C. It is the only hydrocarbon which dissolves in water in all proportions.\tEthanol reacts with alkaline KMnO4 to give ethanoic acid while ethanoic acid does not react with alkaline KMnO4.\tEthanol: Hydroxyl group (-OH group) is the functional group in ethanol. It is the characteristic property of alcohols. All alcohols have at least one –OH group in their structure.\tEthanol: Ethanol neither reacts with Sodium bicarbonate (NaHCO₃) nor changes the colour of a blue litmus paper. Therefore, it is less acidic than ethanoic acid.\tEthanoic acid: It is a weak monoprotic acid in aqueous solution (pKa=4.76). Liquid acetic acid is a polar solvent like water. It dissolves both polar liquids such as sugars and salts, and non-polar liquids such as oils and elements like sulphur and iodine. It is readily and completely miscible with water chloroform, and hexane. Acetic acid has a strong pungent smell.Ethanoic acid: The functional group in ethanoic acid is a –COOH group. It is common for all carboxylic acids.Ethanoic acid: Ethanoic acid is a weak acid which reacts with Sodium bicarbonate (NaHCO₃) releasing Carbon dioxide gas. Also, it turns blue litmus into red. | |
