Answer:
(40 g O) / (15.99943 g O/mol) x (1 mol CaCO3 / 3 mol O) x (100.0875 g CaCO3/mol) =
83 g CaCO3
So answer D), although three significant digits are not justified.
Your welcome! Please give me brainiest and have a Great day! <3
The element is Magnesium
- It has total 12 electrons
it has electronic configuration
or
In valence cell it has 2 electrons and therefore its valency is 2
homogeneous mixture not pure, but is spread out the same throughout
concentration, a measure of the amount of solute dissolved in a solvent
mixture,two or more substances that do not chemically combine, salt and pepper
solute,substance that is dissolved in the solution
Answer: Explanation:
Temperatura. La solubilidad de un soluto en un determinado solvente principalmente depende de la temperatura. Para muchos sólidos disueltos en el agua líquida, la solubilidad aumenta con la temperatura hasta 100 °C, aunque existen casos que presentan un comportamiento inverso.
