1.Temperature :- With increase in temperature the rate of vaporization also increase thus it creates more pressure. Moreover with increase in temperature the kinetic energy of the vapours also increase. 2. Nature of liquid:- The liquids with lower inter-particulate attractions have high vapour pressure as the formation of vapours is easy . Like acetone is
The substances whose conductivity lies between 10-⁶ to 10⁴ ohm-¹ . The range lies between conductors and insulators. Types 1. n-type :- These type of semiconductors have excess electrons present in the lattice that are responsible for the conduction. These are formed when the group 14 elements like Silicon are doped with group 15 elements
This is a best example to share when we talk about chemical change, that the products have totally different properties from that of the reactants , from which they are made. Now coming to the answer, Formation of water is a highly exothermic type of reaction and a lot of energy is lost at the
Here you can see the hybridization of both is same , both of these two elements have seven electrons in outermost shell and below is the diagram showing the electrons filled in s-subshell and p-subshell . one orbital of s- subshell and three orbitals of p-subshell are used during hybridisation. So the type of hybridization
Actually normality depends upon a simple formula that is :- Normality = Number of Gram equivalents / litre The term gram equivalents change as the valency of a substance changes . all the elements do not have same valence and hence it varies from element to element or molecule to molecule. And the term gram
Distillation is a type of separating process in which two miscible liquids are separated from each other by using their different boiling points. the one with lower boiling point , boils first and its vapours are passed through a condenser for cooling and droplets are received on the other side in a beaker. this process
Acid base and salts Acids:- these are the substances that Are sour in taste. Turn blue litmus red. Give H+ ions. Can accept a pair of electrons. Base :- These are the substances that Are bitter in taste. Turn red litmus blue. Soapy in touch. Give OH– ions. How to recognise the acid and bases?
Lets look from a different angle corrosion is basically oxidation and in oxidation the electrons are lost. Here we have zinc coated on iron being more reactive the zinc will tend to loose the electrons even if the iron is exposed, even then being good conductor the electrons are given to the iron by the
