Answer:
Reactants, Activation energy, Energy released by the reaction and Products
Explanation:
This energy profile is that of an exothermic reaction. In an exothermic reaction, heat is liberated to the surrounding. The surrounding becomes hotter than the environment.
The first box to the left is the reactants which signifies the species combining together.
The topmost box is the activation energy which is the energy barrier that must be over come before a reaction takes place.
The box underneath is the energy change. Here, energy is being released.
The right most box is the product of the reaction.

Is the average atomic mass of a sample containing three lithium-6 and two lithium-7 closer to the mass of Li-6 or Li-7 ?
Answers
The average atomic mass of a sample closer to the mass of Li-6
Further explanationIsotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.
So Isotopes are elements that have the same Atomic Number (Proton)
Atomic mass is the average atomic mass of all its isotopes
In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu
Mass atom X = mass isotope 1 . % + mass isotope 2.%
three Li-6, mass number = 6
two Li-7, mass number = 7
total abundance = 5
abundance for Li-6 =
[tex]\tt \dfrac{3}{5}\times 100\5=60\%[/tex]
abundance for Li-7 =
[tex]\tt \dfrac{2}{5}\times 100\5=40\%[/tex]
Average atomic mass :
[tex]\tt (0.6\times 6)+(0.4\times 7)=6.4[/tex]

Would you expect manganese(II) oxide, MnO, to react more readily with HF(aq) or NaOH(aq)?
Answers
Answer:
NaOH(aq)
Explanation:
NaOH(aq) is known to precipitate Mn^2+ ions according to the following reaction; Mn^2+(aq)+2OH^−(aq)↽−−⇀Mn(OH)2(s)
Hence, manganese(II) oxide reacts more readily with NaOH(aq) under ordinary conditions precipitating the metal hydroxide solid. This is one of the characteristic reactions of Mn^2+.

Earth contains a spinning electric filed. The spinning of earth core creates its magnetic field. Thus, option D is correct.
What is a spinning body?A body which rotates in its own axis is called a spinning body. Earth rotates about its along with revolving around sun. The outer core of earth generates electric current. This is called telluric current.
Flow of this current creates an electric current which is parallels to the surface of earth. The direction of magnetic field lines will be perpendicular to the direction of current. But it comes stronger when parallel to current.
A rotating electric current results in the generation of a magnetic field. Thus spinning of earth core generates a magnetic field and therefore, option D is correct.

0.28gram of NH3 on decomposition gave 0.25gram of nitrogen and hydrogen. Find the volume of hydrogen evolved at Ntp. (2gram hydrogen at NTP= 22.4liter)
Answers
The volume of H₂ evolved at NTP=0.336 L
Further explanationReaction
Decomposition of NH₃
2NH₃ ⇒ N₂ + 3H₂
conservation mass : mass reactants=mass product
0.28 NH₃= 0.25 N₂ + 0.03 H₂
2 g H₂ = 22.4 L
so for 0.03 g :

Answers
Answer:
I searched the answer up on Brainly so its not my credit.
Explanation:
The answers D.
"If you have learned that metal + nonmetal ⟶ ionic bond, the answer is D, because N and C are the only pair of nonmetals.
However, if you have learned that a bond is ionic if the electronegativity difference (ΔEN) between the two atoms is greater than 0.7, the answer is A, B, and D.
The Li-Cl bond is definitely ionic.
For Na and C, ΔEN =1.62, so the Na-C bond is a highly polar covalent bond.
For Mg and C, ΔEN = 1.24, so the Mg-C bond is a polar covalent."
