1. (UFJF) Um estudante recolheu 1 litro de soluçāo saturada de sulfato de cobre e, após deixar o recipiente por uma semana na temperatura ambiente, verificou a presença de cristais de sulfalo de cobre e um volume de soluçāo final de 700 mL . Sabendo-se que a solubilidade do sulfato de cobre é de 22.3 g em 100 mL de água, nessa temperatura, qual a massa (em gramas) de sulfato de cobre precipitada?

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 ]
