Element \( X \) has a molar mass of 6.11 g and element Z has á molar mass of 4.74 g . How many moles are in 9.99 g of the compound \( \mathrm{X}_{8} \mathrm{Z}_{6} \) ? Give your answer to the hundredths place in mol. Do not put units in the answer space.

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 ]

Please select polar molecule(s) from the following. NH3 BF3 PF5 PF3

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

Please select the molecule(s) with resonance structures from the following. CCl 4 CHCl 3 SO 3 H 2 O None
