Reply: Bond energy is right proportional to your bond get. Larger the bond get, much more may be the bond toughness.
A metallic ball is whirled inside a ring put on a table, as revealed while in the diagram P. The diagram Q exhibits the movement of the ball after the ring is lifted.
(d) Possibly of these can clearly show a greater adjust in temperature as the temperature transform will depend on factors besides specific warmth ability.
(e) The villi enormously improve the inner surface region of the intestines which facilitates the absorption of digested food stuff.
A college student traces the path of the ray of sunshine by way of a glass prism for various angles of incidence. He analyses Every diagram and attracts the following summary:
Rationalization: Should the function completed is zero, then it doesn’t automatically signifies that the displacement is usually zero. When the displacement is usual into the path of force, then also perform done is zero.
Solution: No, these cannot be taken as canonical sorts since the positions of atoms have already been altered.
(b) The type of tooth revealed while in the provided figure has only one root. As a result This is a canine or incisor that is accustomed to Chunk or pierce.
It is because after dropping an electron, sodium attains the stable noble gasoline configuration. On the flip side, magnesium, after losing on electron still has one electron.
Perseverance of molarity of the specified solution of sodium hydroxide by titrating it against regular Option of oxalic acid.
Micro-chemical strategies can be CBSE Class 11 obtained for quite a few of the practical experiments, where ever possible this kind of approaches should be utilized.
Question 35. Nearly anything that influences the valence electrons will have an effect on the chemistry on the component. Which amongst the next aspects won't impact the valence shell?
IV. Although emerging through the prism at the next surface area, the angle of refraction is under the angle of incidence at that floor.
In contrast, the elements of team 17 have seven electrons in their respective valence shells and so have solid tendency to accept yet one more electron for making steady configuration. It really is linked with electron attain enthalpy and electronegativity. Since both of those of these decreases down the group, the reactivity hence decreases.
