Chapter 2 22. A student heats 0.5585 g of iron with 0.3550 g of sulfur. She reports that she obtains 0.8792 g of iron sulfide and recovers 0.0433 g of unreacted sulfur. Show by calculation whether or not her results obey the law of conservation of mass. Total mass initial = 0.5585 g + 0.3550 g = 0.9135 g Total mass final = 0.8792 g + 0.0433 g = 0.9225 g These two values should be equal by the law of conservation of mass. These results do not obey the law of conservation of mass. Possibly she

Utilization of Camias in the production of “Bilimbi Juice” Camias Averrhoa bilimbi (commonly known as bilimbi‚ cucumber tree‚ or tree sorrel) is a fruit-bearing tree of the genus Averrhoa‚ family Oxalidaceae. It is a close relative of carambola tree. It is very common in Thailand‚ Malaya and Singapore. The bilimbi is closely allied to the carambola but quite different in appearance‚ manner of fruiting‚ flavor and uses. The only strictly English names are "cucumber

Kidney stones are solid lumps of crystals that are separate from urine‚ and they build up on the inner surfaces of the kidneys. Kidneys are the bean shaped organs‚ in the middle part of the back. Each kidney is located in either side of the spine‚ just below the rib cage. Kidney stones can sometimes be undetected. You might not even know you have them‚ until it tries to come out of the urinary tract. Kidney stones have many symptoms. Some of which are: horrible lower back pain‚ pain in the rib

the non-metal that is responsible for the colour produced in the flame test for that salt. How can you be sure your answer is correct? Metal is responsible for the colour produced in the flame test for that salt. All salts contain chloride ion. If non-metal ion‚ chloride‚ is responsible for the colour‚ all colour produced will be the same. 3. Why do the chemicals have to be heated in the flame before the coloured light is emitted? For the coloured light to be emitted‚ the electrons have to get

DOWNLOADED FROM WWW.STUDIESTODAY.COM DOWNLOADED FROM WWW.STUDIESTODAY.COM d – AND f – BLOCK ELEMENTS Electronic Configuration of Transition Metal/Ions The d-block element is called transition metal if it has partly filled d-orbitals in the ground state as well as in its oxidised state. The general electronic configuration of transition metal is (n–1) d1–10ns1–2. Exceptions in electronic configuration are due to (a) very little engery difference between (n–1) d and ns orbitals and (b) extra stability
