Answer only number 1 II. Reaction Stoichiometry1. Gallium chloride is formed by the reaction of 2.6 L of a 1.44 M solution of HCI according tothe following equation:2Ga + 6HCI→→ 2GaCl₂ + 3H₂(a) Outline the steps necessary to determine the number of moles and mass of galliumchloride.(b) Perform the calculations outlined.2. Silver is often extracted from ores such as K[Ag(CN)₂] and then recovered by the reaction2K[Ag(CN)₂] (aq) + Zn (s) 2Ag (s) + Zn(CN)2 (aq) + 2KCN (aq)(a) How many molecules of Zn(CN)2 are produced by the reaction of 35.27 g ofK[Ag(CN)₂]?(b) What mass of Zn(CN)₂ is produced?3. Carborundum is silicon carbide, SiC, a very hard material used as an abrasive on sandpaperand in other applications. It is prepared by the reaction of pure sand, SiO2, with carbon at hightemperature. Carbon monoxide, CO, is the other product of this reaction. Write the balancedequation for the reaction, and calculate how much SiO₂ is required to produce 3.00 kg of SiC.4. Urea, CO(NH2)2, is manufactured on a large scale for use in producing urea-formaldehydeplastics and as a fertilizer. What is the maximum mass of urea that can be manufactured fromthe CO₂ produced by combustion of 1.00 x 10³ kg of carbon followed by the reaction?CO₂ (g) + 2NH3(g) CO (NHz)z (s) + H2O (I)
