You met Mr. Yap, CEO of a Penang-based semiconductor producing company. Mr. Yap mentioned that they were using NaOH to treat and dispose HF waste as part of their commitments to abide by the legislation and laws in Malaysia. Explain how you would recommend calcium oxide produced in your company to Mr. Yap as a replacement material for NaOH. Use a table when appropriate. Molecular weights: HF=20.01 g/mol CaF₂=78.07 g/mol Ca(OH)2 74.093g/mol NaF=41.98 g/mol NaOH=39.99g/mol
