Respond to: Bond toughness is specifically proportional into the bond order. Greater the bond get, far more is definitely the bond energy.
Reply: Modem Periodic Law states that Bodily and chemical Qualities of the elements are a periodic operate in their atomic numbers.
Inside the diagram beneath, 4 cones are depicted, Each individual with a top of 12cm. The placement of the center of gravity is indicated by dots located at 9cm, 8cm, 4cm, and 3cm with the apex of every cone. Which of such cones is completely strong?
The chapter bargains with the Qualities of changeover features, coloured ions and complex compounds, variation in sizes of factors, ionization enthalpies, magnetic properties, and oxidation states. The chapter bargains with d block aspects as well as their Attributes and variations.
The supplied determine depicts the graph of labor carried out vs. displacement below a relentless drive of 10N. Which of the subsequent statements is true?
Clarification: Ice has higher particular latent warmth of fusion. Which means, it requires a lot of warmth to melt.
