[Terjawab] 1. The reaction of calcium hydride with water can be used to prepare small quantities of hydrogen gas, as is done to fill weather-observation balloons.2.CaH2(s) + H2O(1) Ca(OH)2(s) + H2(g) (not balanced)(a) How many grams of H2(g) result from the reac-tion of 127 g CaH2 with an excess of water?(b) How many grams of water are consumed in the reaction of 56.2 g CaH2?(c) What mass of CaH2(s) must react with an excess of water to produce 8.12 × 1024 molecules of H₂?A side reaction in the manufacture of rayon from wood pulp is 3 CS2 + 6 NaOH→ 2 Na2CS3 + Na2CO3 + 3 H2OHow many grams of Na2CS3 are produced in the reac-tion of 92.5 mL of liquid CS2 (d = 1.26 g/mL) and 2.78 mol NaOH?3. Titanium tetrachloride, TiCl, is prepared by the reac-tion below.3 TiO2(s) + 4 C(s) + 6 Cl₂(g) 3 TiCl4(g) + 2 CO2(g) + 2 CO(g)What is the maximum mass of TiCl, that can be obtained from 35 g TiO2, 45 g Cl₂, and 11 g C?4. In the reaction shown, 100.0 g C6H11OH yielded 64.0 g C6H10. (a) What is the theoretical yield of the reaction?(b) What is the percent yield? (c) What mass ofC6H11OH would produce 100.0 g C6H10 if the percent yield is that determined in part (b)? C6H11OH→ C6H10 + H2O5. Azobenzene, an intermediate in the manufacture of dyes, can be prepared from nitrobenzene by reaction with triethylene glycol in the presence of Zn and KOH. In one reaction, 0.10 L of nitrobenzene (d 1.20 g/mL) and 0.30 L of triethylene glycol (d 1.12 g/mL) yields 55 g azobenzene. What are the (a) theoretical yield, (b) actual yield, and (c) percent yield of this reaction? 2 C6H5NO2 + 4 C6H14O4 nitrobenzene triethylene glycol Zn KOH (C6H5N)2+4C6H12O4+4 H₂O azobenzene​
