Write balanced chemical equations for the reactions used to prepare each of the following compounds from the given starting material(s). In some cases, additional reactants may be required. (a) solid ammonium nitrate from gaseous molecular nitrogen via a two-step process (first reduce the nitrogen to ammonia, then neutralize the ammonia with an appropriate acid) (b) gaseous hydrogen bromide from liquid molecular bromine via a one-step redox reaction (c) gaseous H2S from solid Zn and S via a two-step process (first a redox reaction between the starting materials, then reaction of the product with a strong acid)
Which of the following compounds have the same oxidation level, and which have different levels?
. For each of the following unbalanced oxidation-reduction chemical equations, balance the equation by inspection, and identify which species is the reducing agent. a.Fe(s)+O2(g)Fe2O3(s)b.Al(s)+Cl2(g)AlCl3(s)c.Mg(s)+P4(s)Mg3P2(s)
The respiration reaction is shown below. Identify the oxidizing agent. C6H12O66O26CO2+6H2O a.C6H12O6b.O2c.CO2d.H2O
The iron content of hemoglobin is determined by destroying the hemoglobin molecule and producing small water-soluble ions and molecules. The iron in the aqueous solution is reduced to iron(II) ion and then titrated against potassium permanganate. In the titration, iron(ll) is oxidized to iron(III) and permanganate is reduced to manganese(II) ion. A 5.00-g sample of hemoglobin requires 32.3 mL of a 0.002100 M solution of potassium permanganate. The reaction with permanganate ion is MnO4(aq)+8H+(aq)+5Fe2+(aq)Mn2+(aq)+5Fe3+(aq)+4H2O What is the mass percent of iron in hemoglobin?
Determine the oxidation states of the elements in the compounds listed. None of the oxygen-containing compounds are peroxides or superoxides. (a) H2SO4 (b) Ca(OH)2 (C) BrOH (d) ClNO2 (e) TiCl4 (f) NaH
Complete and balance the following oxidation-reduction reactions, which give the highest possible oxidation state for the oxidized atoms. (a) Al(s)+F2(g) (b) Al(s)+CuBr2(aq) (single displacement) (c) P4(s)+O2(g) (d) Ca(s)+H2O(l) (products are a strong base and a diatomic gas)
Q6. The reaction of NH3 and O2 forms NO and water. The NO can be used to convert PA to P,06, forming N2 in the process. The P,O can be treated with water to form HyPO3, which forms PH and H3POA when heated. How many grams of NH are needed to produce 20.44 g of PHz? Q9. The purity of a refined silicon sample can be tested by the redox reaction between NaOH and silicon as seen below. If 76.0 g of NaOH yielded 3.52 g of hydrogen gas, calculate percent impurity by mass. Si(g) + NaOH(aq) + H201) - > Na2SiO3(aq) + H2(g) Q10. A chemistry student was assigned to determine the empirical formula of an unknown compound. She first burns 23.58 g of unknown compound in excess oxygen, 52.33 g of CO2, and 23.56 g of H20 was determined. On a second attempt, the nitrogen content of a 3.72 g of the compound was converted to 1.051 g of nitrogen gas. What is the empirical formula of the compound?
