Answer:
[Fe(NO₃)₃] = 0.90 M
Explanation:
Molarity = Mol/L
Total volume of solution: 31.65 mL + 44.96 mL = 76.61 mL
Let's determine the moles of salt ([M] . volume)
0.03165 L . 1.07M = 0.0338 moles
0.04496L . 0.79M = 0.0355 moles
Total moles Fe(NO₃)₃ = 0.0338 + 0.0355 = 0.0693 moles
Volume of solution = 76.61 mL = 0.07661 L
0.0693 mol / 0.07661 L = 0.90 mol/L
Explanation:
how are you confused there just tell me the problem
Single-displacement reaction occurs when aluminum reacts with copper nitrate.
Single-displacement reaction is the type of chemical reaction that occurs when aluminum (Al) reacts with copper nitrate (Cu(NO3)2). In this type of reaction, aluminum takes the place of copper and produced aluminium nitrate.
Aluminum does not react with potassium nitrate (KNO3) although it reacts with copper nitrate because potassium nitrate (KNO3) is a stable compound which held each other very tightly so we can conclude that Single-displacement reaction occurs when aluminum reacts with copper nitrate.

<h3><u>Answer;</u></h3>
D. All the above
- Covalent compounds are always poor conductors of electricity while ionic compounds conduct electricity well when melted or dissolved.
- Covalent compounds can be solid, liquid or gas, but ionic compounds are solids.
- In covalent compounds the elements present are usually close together on the periodic table whereas in ionic compounds they are usually well separated.
<h3><u>Explanation;</u></h3>
- <u>Ionic compounds are compounds that are formed from strong electrostatic interactions between ions.</u> Ionic bonding occurs between a nonmetal, which acts as an electron acceptor, and a metal, which acts as an electron donor. The atoms involved in ionic bonding lose or gain electrons and form positively or negatively charged ions.
- <em><u>Ionic compound are good conductors of electricity both in molten and aqueous form,. while covalent compound are poor conductors of electricity.</u></em>
- <u>Covalent compounds on the other hand are compounds that have bonds where electrons are shared between atoms.</u> These types bonds mostly occur between nonmetals or between two atoms of the same element.
The question is partially incorrect, because nitration of <span> methyl benzoate results in generation of methyl 3-nitrobenzoate, and not methyl 2-benzoate.
This a because of the present of ester group, which deactivated benzene ring at ortho and para position. Due to this, the electrophile (NO2+) attackes on meta position.
