Zinc is a lustrous bluish-white metal. It is brittle and crystalline at ordinary temperatures but it becomes ductile and malleable when heated between 110°C and 150°C. It is a reactive metal that can combine with oxygen and other non-metals and will react with dilute acids to release hydrogen. Mostly zinc is used for galvanizing iron with more than 50% of metallic zinc goes into galvanizing steel and in the preparation of certain alloys. Then‚ zinc is added during industrial activities such as mining

Report on Zinc deficiencies Zinc deficiency is the inadequate amount of zinc in the body to meet its demands. Zinc is vital to the body functions such as‚ a healthy immune system and wrongdiagnosis.com states is best known for minimizing the effects of the common cold or upper respiratory infections. It can enhance the functions of the liver‚ muscles and bones. Other functions of zinc in the body are to wound heals; aid enzyme activity; DNA production and cell division.

Zinc oxide in a mixture with a about 0.5% iron(III) oxide (Fe2O3) is called calamine and is used in calamine lotion. There are also two minerals‚ smithsonite and hemimorphite‚ which have been called calamine historically (see: calamine (mineral). Zinc peroxide‚ ZnO2 .½ H2O‚ is a white to yellow powder that is used in antiseptic ointments. Zinc white is used as a pigment in paints and is more opaque than lithopone‚ but less opaque than titanium dioxide. It is also used in coatings for paper

Synthesis and Decomposition of Zinc Iodide Partners: Sonya Pasia and Kristen Kobayashi CH 085-01 20 September 2011 Zinc Iodide (ZnI2) was an interesting binary compound to experiment with. In this experiment‚ weakly acidified water (25mL distilled water with 18 drops 5M acetic acid solution) was used as an aid to bring molecules of the zinc and iodide atoms together‚ by dissolving iodine molecules‚ so that bonding would transpire to produce a reaction. Deprived of water‚ the Zn and I2

Divya Nagendran Professor Patrick Crawford CHEM 122-04 27 January The Role of Zinc in My Life Chemistry plays a vital role in our daily life. We find chemistry in every object we see or touch. We could find chemistry in the food we eat‚ the air we breathe‚ our acne treatment cream and the list goes on. There is one chemistry element that is important in my daily life and its Zinc or Zn 2+. During my high school year‚ I’ve had problems with hair loss. Each day I would lose 100 to 125 strands

“The Synthesis of Zinc Chloride”‚ what a peculiar name for a lab that does not even involve synthesis. Synthesis‚ by definition‚ is when two elements are combined in a chemical reaction‚but that is not the case. In this lab we are combining zinc‚ an element‚ and hydrochloric acid‚ a compound‚ but combining a compound and an element is not synthesis‚ it is single replacement. We are taking zinc and hydrochloric acid and making zinc chloride and hydrogen‚ a single replacement‚ but what occurred during

DETERMINATION OF THE THICKNESS OF ZINC ON A PIECE OF GALVANIZED METAL Department of Biology‚ College of Science‚ University of the Philippines Baguio ABSTRACT The experiment was performed to be able to determine the thickness of zinc on a piece of galvanized metal. It also aimed for the students to be introduced to the reactivates of metals with acids as well as for them to develop some feeling for the size of an atom. In determining the thickness of the zinc coating on the metal‚ students
