WebZinc sulfide reacts with oxygen according to the reaction: 2 ZnS(s) + 3 O2(g)-2 ZnO(s) + 2 SO2(g) Let's see here So 6.8 times two divided by three would be 4.53 moles of zinc If this completed, this would be a 1 to 1 ratio and therefore we get 4.2 moles of products. The ionization energy of xenon is low enough for the electronegative oxygen atom to capture electrons. These compounds tend to be effective oxidizing agents due to the fact that O2- is one electron short of a complete octet and thus has a strong affinity for another electron. Write word, equation, and formula: Aqueous nitric acid reacts with sold magnesium hydroxide to produce aqueous magnesium nitrate and water. Find the Zinc (II) sulfide reacts with oxygen according to the reaction below: 2 ZnS (s) + 30 2 (g) 2 ZnO (s) + 2 SO 2 (g) a. Rock ) pic hide this posting restore restore this posting Saw with Diablo blade Saw Quebec Spa fits almost any location product details right Tools on sale help! The equation for the formation of the simple oxide is analogous to that for lithium: \[ 4Na(s) + O_2 (g) \rightarrow 2Na_2O (s) \label{5}\]. Molar mass of C7H6O3 = 136, Q:Chlorine gas can be made from the reaction of manganese dioxide with Aluminum trioxide, Al2O3, is amphoteric (acts both as an acid and a base): \[Al_2O_3(s) + 6HCl(aq) \rightarrow 2AlCl_3(aq) + 3H_2O(l) \label{20}\], \[Al_2O_3(s) + 2NaOH(aq) + 3H_2O(l) \rightarrow 2Na[Al(OH)_4](aq) \label{21}\], Except for thallium in which the +1 oxidation state is more stable than the +3 state, aluminum, gallium, and indium favor +3 oxidation states.

SO2 is mainly used to make SO3, which reacts with water to produce sulfuric acid (recall that nonmetals form acidic oxides). Shop Grainger Canada for quality Band Saw Blades products. Aluminum + zinc chloride > zinc + aluminum chloride, Translate into words: 3KOH(aq) + H3PO4(aq) > K3PO4(aq) + 3H2O(l), Aqueous solutions of potassium hydroxide and phosphoric acid react to produce potassium phosphate in aqueous solution and water, Translate into words: FeS(s) + HCL(aq) > FeCl2(s) + H2S(g). All are powerful oxidizing agents. c. Liquid butane (C4H10 ()) is used as a fuel to ignite a lighter. Introduction:, Q:Aspirin, C6H4 (OCOCH3)CO2H, is produced by the reaction of salicylic acid, CgH4 (OH)CO,H, and acetic, A:Given mass of reactant = 160 g We confirm it by a rule of three, 2 moles of sulfide can react to 3 moles of O, Therefore 3 moles of ZnS will react to (3 . -hydrogcarbons form CO2 + H2O Oxygen was discovered by Joseph Priestley in 1774 when he heated mercury(II) oxide to decompose it to form its constituent elements. AgNO3(aq) + NaCl(aq) ---> AgCl(s) + NaNO3(aq) When 83.2 g of Zn reacts with 52.4 g of S8, 104.4 g of ZnS forms. Because alkali metals always have a +1 oxidation state, oxygen is in the O22- form. If 7.6 gram are produced determine the percent yeild of reaction, c. How much of excess reagent is left over at end of reaction, 16.7 g ZnS x 1 mole/97.4 g = 0.171 mole ZnS, moles ZnO formed = 0.209 moles O2 x 2 moles ZnO/3 moles O2 = 0.139 moles ZnO, mass ZnO = 0.139 moles x 81.4 g/mole = 11.3 grams, (b) percent yield = actual/theoretical (x100) = 7.6 g/11.3 g (x100%) = 67.3% yield, (c) 0.209 moles O2 x 2 moles ZnS/3 moles O2 = 0.139 moles ZnS used, moles ZnS left over = 0.171 moles - 0.139 moles = 0.032 moles, If you want mass left over, multiply moles x molar mass, a Question Now let's check it for oxygen, which has three moles reacting, forming again two moles of zinc oxide reacting. Magnesium, calcium, strontium and barium oxides react with water to form hydroxides: \[ MO(s) + H_2O(l) \rightarrow M(OH)_2(s) \label{14}\]. How many moles of ammonia are produced when 6 mil of hydrogen gas reacts with an excess of nitrogen gas? CO But we also know that we started with 6.8 moles. Pb(NO3)2(aq) + K2CrO4(aq) > PbCrO4(s) + 2KNO3(aq). (a) N2 is the limiting reactant. Write a balanced chemical equation for this reaction. WebSolid zinc (II) sulfide reacts with aqueous hydrobromic acid (HBr) to form aqueous zinc (II) bromide and dihydrogen sulfide gas. $$\ce {H2S + Na2CO3 NaHS + NaHCO3}$$ Conditions: Hydrogen sulfide react with sodium carbonate to produce sodium bisulfide and sodium bicarbonate.
