3. In un reparto di un'azienda di cosmetici sono presenti tre linee di prodotti: creme, deodoranti e saponette. Su tali prodotti vengono eseguiti controlli di qualità, attraverso specifici test nei laboratori chimici, con un costo settimanale di \( € 4.550 \) \( € \). Il costo viene suddiviso tra le tre linee in proporzione alle ore di produzione e al numero di prodotti lavorati. I dati sono i seguenti: - Linea creme: ore di produzione 35; pezzi lavorati 6.300 - Linea deodoranti ore di produzione 25; pezzi lavorati 9.800 - Linea saponette ore di produzione 10; pezzi lavorati 3.000

Based on your worksheet results, please match the following: The electron group geometry of NH 3 is The electron group geometry of BF 3 is [Choose ] The electron group geometry of \( \mathrm{PF5} \) is [Choose ] [Choose ] electron group geometry of SF4 is geometry of PF 3 is [Choose ]

Please select the molecule(s) that 1) its molecular shape is different from its electron group shape, and/or 2) the central bonds are not identical. NH3 BF3 PFF PF3

There are different types of food coloring available in most grocery stores- one that is water-based, and one that is oil-based. The oil-based food coloring works best in chocolates, in fry-oil to color fried foods, and in food with high butter contents. Based off of this information and knowing that substances of like polarity mix readily with one another, which food coloring is more polar (water-based or oil-based)? Which food coloring is less polar (or even nonpolar)? Water-based [Choose ]
