The Synthesis Reaction of aluminum (Al) and iodine (I) forms a new, more complex
product. What is the product?
Answers
Answer:
Aluminum iodide (AlI₃)
Explanation:
The synthesis reaction of aluminum (Al) and iodine (I) can be illustrated as shown below:
Aluminium exhibit trivalent positive ion (Al³⁺)
Iodine exhibit univalent negative ion (I¯)
During reaction, there will be an exchange of ion as shown below:
Al³⁺ + I¯ —> AlI₃
Thus, we can write the balanced equation for the reaction as follow:
Al + I₂ —› AlI₃
There are 2 atoms of I on the left side and 3 atoms on the right side. It can be balance by putting 2 in front of AlI₃ and 3 in front of I₂ as shown below:
Al + 3I₂ —› 2AlI₃
There are 2 atoms of Al on the right side and 1 atom on the left side. It can be balance by putting 2 in front of Al as shown below:
2Al + 3I₂ —› 2AlI₃
Thus the equation is balanced.
The product on the reaction is aluminum iodide (AlI₃)

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 :

The fence is 2 meters feet tall. How tall
is the fence in centimeters?
Answers
Answer:
2 meters equal 200 centimeters
Explanation:
1 meter is equal to 100 centimeters.
Hope this helped, have a good day!
For a fence is 2 meters feet tall, the fence is 183.92 centimeters tall.
How to find centimeters?There are 0.3048 meters in 1 foot. So, a 2 meters fence is equal to 2 x 0.3048 = 0.6096 feet tall.
To convert feet to centimeters, multiply the number of feet by 30.48. So, a 0.6096 feet fence is equal to 0.6096 x 30.48 = 183.92 centimeters tall.
Therefore, the fence is 183.92 centimeters tall.
Feet to centimeters:
1 feet = 30.48 centimeters
0.6096 feet × 30.48 centimeters/feet
= 183.92 centimeters

What is Electromagnetic Energy ?
Electromagnetic energy consists of waves of the electromagnetic field, propagating through space, carrying electromagnetic radiant energy.
It includes radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum.
A unification criterion holds that a theory is empirically successful, and thus confirmed, to the ex- tent that it predicts or explains a large number of empirical results by ap- pealing to only a relatively small number of basic principles.
Theerfore, The statement which best describes how scientists arrived at the current understanding of electromagnetic energy is (C) Scientists debated the theories with each other and compared the theories with scientific observations. hence option (C) is correct.

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."

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.
