1. The galvanizing of iron sheet can be carried electrolytically using a bath containing zinc sulfate solution. The sheet is made the cathode, and a graphite anode is used. Calculate the cost of electricity required to deposit 0.49 mm layer of zinc on both sides of an iron sheet 2.0m wide and 80m long if the currentis 30 A, the voltage is 3.5 V, and the energy efficiency of the process is 90%. Assume the cost of electricity is Php 12.50 per kilowatt-hr. The density of zinc is 7.1g/cm?.

4) But the real angler continues, regardless of the local sage. What sort of tone does the author create by using the connotative effects of the word sage in paragraph 6? The word "sage" is used primarily as a joke, gently mocking the fishing guide who cannot force fish to A) appear or guarantee good fishing to a paying customer. Primarily, the author is creating None of awe or B) respect for the great wisdom and power that the Eiminate sage, or fishing guide, holds in his mind. The author is being highly critical, even condemning. of the ignorance of these so-called "sages who can't help fisherman catch fish. The word sage" in this context has no connotaive D) effect on the tone or meaning of this entire passage.
A 0.1 g amine-containing compound is dissolved in water then diluted to 100 mL. To get the concentration of amine in this compound, you subject it to spectroscopic analysis. So, you get 1 mL of the previously diluted sample then dilute it again to 250 mL for measurement. Then, you fill 3/4 of a 1-cm cuvette with this diluted sample then you run an analysis using an AAS. The recorded absorbance is 0.545 at 410 nm. Solve for the molecular weight of the compound. The molar absorptivity is 1.23 x 104 cm-1 mol-1 L.
