(c) The atoms lose their electrons more easily. As we move from left to right across the periods of the periodic table, the non-metallic character increases. So, the tendency to lose electrons decreases.

The dirt present on clothes is oily in nature and insoluble in water. Therefore, it cannot be removed by only washing with water. When soap is dissolved in water, its hydrophobic ends attach themselves to the dirt and remove it from the cloth. Then, the molecules of soap arrange themselves in micellRead more
The dirt present on clothes is oily in nature and insoluble in water. Therefore, it cannot be removed by only washing with water. When soap is dissolved in water, its hydrophobic ends attach themselves to the dirt and remove it from the cloth. Then, the molecules of soap arrange themselves in micelle formation and trap the dirt at the centre of the cluster. These micelles remain suspended in the water. When flushed with excess water, the dust particles are easily rinsed away by water.
Butter contains saturated fats. Therefore, it cannot be hydrogenated. On the other hand, oil has unsaturated fats. That is why it can be hydrogenated to saturated fats (solids). Bromine water test - Cooking oil will decolourise the red colour of bromine water on shaking while butter will not.

Hydrogenation is the process of addition of hydrogen to unsaturated hydrocarbons in the presence of palladium and nickel catalysts to give saturated hydrocarbons. This reaction is applied in the hydrogenation of vegetables oils, which contain long chains of unsaturated carbons.
