Dear Student, The reaction is: 2 Zn + O 2 = 2 ZnO So, the word equation is: Zinc + oxygen = Zinc oxide Regards. The theoretical electromotive force is +2.36v + 0.76v = +1.6v, meaning if the the two metals were used in a galvanic cell, the cell would theoretically be able to achieve a total of 1.6 volts. Zn + S -----> ZnS Zn=0.3803 mol S=0.9356 mol If 25.0 g of zinc and 30.0 g of sulphur are mixed, a) Which chemical is the limiting reactant? The substance(s) to the left of the arrow in a chemical equation are called reactants. In the chemical equation Zn + 2HCL ZnCl2 + H2, the reactants are A. zinc and hydrochloric acid. Advertisement Remove all ads. The obtained AIS/ZnS core/shell QDs exhibited a considerable enhancement of QYs from 21.6% to 45.7%, and their PL lifetimes could reach up to 482.2 ns. Zn + S → ZnS. There are three main steps for writing the net ionic equation for Zn + CuSO4 = ZnSO4 + Cu (Zinc + Copper (II) sulfate). Zn + I 2 ZnI 2 [ Check the balance ] Zinc react with iodine to produce zinc iodide. Net ionic equation: Mg(s) +Zn2+(s) --> Mg2+(s) + Zn(s) Here zinc's oxidation state is reduced from 2+ to 0 and Mg is oxidized from 0 to 2+. Identify all of the phases in your answer. (we will look at this a little later): Add any extra details to the equation e.g. Word Equations Write the word equations for each of the following chemical reactions: 1) When dissolved beryllium chloride reacts with dissolved silver nitrate in water, aqueous beryllium nitrate and silver chloride powder are made. The atomic weight of zinc is 65.37 and so if we start with 25 grams, that is 25/65.37, or 0.3824 mole of zinc. C 12 H 22 O 11 + O 2 CO 2 + H 2 O Combustion 9. 2) When isopropanol (C 3 H 8 O) burns in oxygen, carbon dioxide, water, and heat are produced. This is something that you should be able to get quite good at it. 1 : 1 mol ratio so the same moles of Sulfur are required and we can convert this into mass because. Zinc and sulfur react to form zinc sulfide according to the equation. Zinc and Lead (II) nitrate react to form Zinc Nitrate and Lead. See the answer Check that the atoms are in fact balanced. produces 1 mole of ZnS if there is enough sulfur so all the zinc reacts. Aluminum Bromide and Chlorine gas react to form Aluminum Chloride and Bromine gas. Zn + Pb(NO 3) 2 Zn(NO 3) 2 + Pb Single Replacement 2. Share with your friends. what is the word equation for zn + cuso4 =znso4 + CU - 16494978 What mass of zinc sulfide can be produced from the reaction of 130.8 g of zinc reacting with 256.6 g of sulfur? The Equation for the reaction is : Zn + S = ZnS, but I am not sure as the mixture is heated in presence of oxygen. Use uppercase for the first character in the element and lowercase for the second character. EXAMPLE Zinc and sulfur react to form zinc sulfide, a substance used in phosphors that coat the inner surfaces of TV picture tubes. To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. H 2 SO 4 + Fe H 2 + FeSO 4 Single Replacement 8. Given the equation: #8Zn +S_8 -> 8ZnS#, if 7.36 g of zinc react with 6.45 g of sulfur, which is the limiting reactant and what mass of zinc sulfide forms? The equation for the reaction is Zn + S-----> ZnS In a particular experiment 12.0 g of Zn are mixed with 6.50 g S and allowed to react. Zn + S ZnS Synthesis 5. Al 2 S 3 Al + S Decomposition 7. The reaction of elemental zinc with arsenic acid in acidic solution yields arsine AsH 3 a highly toxic and unstable gas and Zn 2 aq . If you made a purchase, and presented the cashier with a large denomination banknote, the value of your purchase + the value of your change MUST equal the value of the banknote. Log in: Chemical reactions Сhemical tables. c) How many grams of the excess reactant will remain after the reaction is over? Syllabus. Worked example 1: Balancing chemical equations 1 When zinc metal and sulfur powder are heated, they form solid zinc sulfide. Zn + S -----> ZnS If 25.0 g of zinc and 30.0 g of sulfur are mixed, a) Which chemical is the limiting reactant? Textbook Solutions 6493. write the half reactions and the net equation a) zinc is an active metal that oxidizes quickly when exposed to air and water ok so heres what i have to far Zn = Zn2+ + 2 e- Zn + H2O = ZnO + 2H+ + 2e but i dont think its right Concept Notes & Videos & Videos 103.
