The labeled diagram is located on the first uploaded image
What determines the solvent that is the upper and the one that is the lower is density
2
The distribution is in this manner neutral organic product would move to organic layer while charge product would go to aqueous layer and then for the inorganic by-product it would move to the aqueous layer
Explanation:
Looking at question one, to further explain when a solvent has a greater density than the solution it stays at the lower layer while the one with a lower density would stay above it
Answer:
- Question 19: the three are molecular compounds.
Explanation:
<em>Question 19.</em>
All of them are the combination of two kinds of different atoms in fixed proportions.
- C₂H₄: two carbon atoms per four hydrogen atoms
- HF: one hydrogen atom per one fluorine atom
- H₂O₂: two hydrogen atoms per two oxygent atoms
Thus, they all meet the definition of compund: a pure substance formed by two or more different elements with a definite composition.
Molecular compounds are formed by covalent bonds and ionic compounds are formed by ionic bonds.
Two non-metal elements, like H-F, C - C, C - H, H-O, H - H, and O - O will share electrons forming covalent bonds to complete their valence shell. Thus, the three compounds are molecular and not ionic.
<em>Question 20. </em>Formula of copper(II) sulfate hydrate with 36.0% water.
Copper(II) sulfate is CuSO₄. Its molar mass is 159.609g/mol
Water is H₂O. Its molar mass is 18.015g/mol
Calling x the number of water molecules in the hydrate, the percentage of water is:
From which we can solve for x:
Thus, there are 5 molecules of water per each unit of CuSO₄, and the formula is:
An exothermic reactions experiment and endothermic reactions experiment.
Historically, the left hemisphere was seen as the dominant hemisphere of the brain.
