Answer:
Sugar can be obtained by evaporation.
Filtering wont work because sugar is soluble in water thus will mix to form one layer.
Answer:
0.670 mol
Explanation:
Step 1: Write the balanced reaction for the decomposition of alumina
2 Al₂O₃ ⇒ 4 Al + 3 O₂
Step 2: Calculate the moles corresponding to 34.2 g of Al₂O₃
The molar mass of Al₂O₃ is 101.96 g/mol.
34.2 g × 1 mol/101.96 g = 0.335 mol
Step 3: Calculate the moles of Al produced from 0.335 moles of Al₂O₃
The molar ratio of Al₂O₃ to Al is 2:4.
0.335 mol Al₂O₃ × (4 mol Al/2 mol Al₂O₃) = 0.670 mol Al
Transition Metals can have more than one possible charge.
A circle or square that is not shaded indicates that a person neither expresses the trait nor is a carrier of the trait. within a family, is used. In a pedigree, a circle represents a female, and a square represents a male. A filled-in circle or square shows that the individual has the trait being studied.
Avogadro’s number allows you to change moles to number of molecules/atoms.
