precipitation reaction? Give its one example. Q. 14. What is redox reactions? Give its two examples? Q. 15. Write the balanced chemical equation of the following and identify the type of reaction in each case: i. Potassium bromide(aq) = barium iodide(aq) -> potassium iodide(aq) = bariumbromide(s) ii. Zinc carbonate(s) -> zinc oxide(s) = carbon dioxide(g) iii. Magnesium(s) = hydrochloric acid(aq) -> magnesium chloride(aq) = hydrogen(g) Q. 16. Wrte an activity to shw the change

eaves‚ meaning lower edges of a roof to define where a swallow (her daughter) would lay in the night. She also uses the terms swallow‚ princess‚ and queen to symbolize her daughter growing from a sweet‚ needy infant to an independent‚ careless adult.

The speaker‚ her mother‚ uses the term swallow to represent her daughter growing up and leaving‚ no longer

Abstract Gold‚ silver‚ copper‚ lead‚ and mercury are some of the ancient elements. Hennig Brand discovered phosphorus the first element. After the discovery of phosphorus‚ many more elements were discovered. Johann Dobereiner discovered that elements could be grouped in three sets and proposed the Law of Triads. Later‚ A.E.Beguyer de Chancourtois arranged the elements according to their atomic mass and created the first geometrical representation of the periodic table. John Newlands proposed the

1. Sodium and potassium are the most frequently ecountered alkali metals‚ though rarely as the metal. Why these elements are rarely found as the metal? (Refer to the relative measurements tabulated in the form of electronegativities‚ ionization energies‚ or reduction potentials). These are due to the fact that their outer most orbital (ns1 valence electron configuration) has tendency to lose electron very easily and make stable configuration. The single valence electron is relatively far from the
