What is the bond order for a single covalent bond?
Answer:
We typically represent covalent bonds with a dash ( - ) between the atoms. This indicates a single bond. Ex: Cl - Cl
Single bond, double bond, triple bond.
Explanation:
We call it a single covalent bond because the atoms are sharing a single pair of electrons.

An object is located 360 millimeters from a converging lens. The image formed is 150 millimeters high, at a distance of 90 millimeters from the lens. What’s the height of the object?
The height of the object : 600 mm
Further explanationGiven
d object=360 mm(object distance)
d image=90 mm(image distance)
Required
h object
Solution
focal length = f :
[tex]\tt \dfrac{1}{f}=\dfrac{1}{d_o}+\dfrac{1}{d_i}\\\\\dfrac{1}{f}=\dfrac{1}{360}+\dfrac{1}{90}\rightarrow f=72~mm[/tex]
The magnification :
[tex]\tt M=\dfrac{d_i}{d_o}=\dfrac{90}{360}=0.25[/tex]
[tex]\tt M=\dfrac{h_i}{h_o}\\\\0.25=\dfrac{150}{h_o}\rightarrow h_o=600~mm[/tex]

A magnesium atom that loses 2 electrons becomes a
A) Positive ion with a smaller radius
B) Positive ion with a larger radius
C) Negative ion with a larger radius
D) Negative ion with a smaller radius
Answer:
A
Explanation:
because the atomic radius reduced by loosing one energy level leading to a positive ion in the resulting ion
The study of chemicals and their bond is called chemistry.
The correct answer is A.
The metals have the property to lose electrons to become stable compounds.
In magnesium, the total number of electrons is 12. In a valance shell, they have 2 electrons.
when they lose or donate the two electrons to the other. The outer shell will be empty and the force of the nucleus remains in the inner shell.
The loss of electrons leads to a decrease in the size of an atom and form positive ions.
Hence, the correct answer is A that is a Positive ion with a smaller radius.

Use your knowledge of modern atomic theory and bonding to explain each of the following experimental observations. (Your explanations should be specific.) Refer to both substances when comparing. Within a family such as the alkaline earth metals, the ionic radius increases as the atomic number increases. The radius of the bromine atom is smaller than the radius of the bromide ion, Br-1. The first ionization energy of aluminum is lower than the first ionization energy of magnesium.
Answer:
(1) In the modern day periodic table the atomic size is increasing when we move down the group and it decreases when we move along the period from left to right. that's why Within a family such as the alkaline earth metals, the ionic radius increases as the atomic number increases. Alkaline earth metals have loosely held electrons which results in its increased size.
(2) The radius of the bromine atom is smaller than the radius of the bromide ion, Br-1 this happens because bromine is a non metal, and it also has a high electronegativity among other group elements as halogen group has high electronegativity. when the bromine acquires one extra electron and forms [tex]Br^-[/tex] ion, the configuration of bromine earlier was [tex]1s^22s^22p^63s^23p^64s^23d104p^5[/tex] but on addition of the electron the p shell will now have 6 electrons resulting in [tex]1s^22s^22p^63s^23p^64s^23d104p^6[/tex]the newly added electron repels the former neutral orientation and as a result of repulsion the size increases.
(3) The first ionization energy of Aluminum is lower than that of the first ionization energy of magnesium because magnesium has fully filled [tex]3s^2[/tex] orbital whereas Aluminum has one electron in the 3p orbitals, fully filled 3s orbitals has strongly held by the nucleus in case of Mg whereas 3p orbitals is shielded from the nucleus therefore it becomes easy to take out 3p electron that 3s electron.

Help needed: Which of the following is the correct name for N2S5?
A. Dinitrogen sulfide
B. Dinitride pentasulfur
C. Dinitrogen pentasulfide
D. Nitrogen sulfide
Answer:
dinitrogen pentasulfide
Explanation:
The correct name for the compound N₂S₅ is Dinitrogen pentasulfide and the correct option is option C.
Naming of compounds refers to the systematic process of assigning names to chemical compounds based on their composition and structure. It involves following certain rules and conventions to generate appropriate names that accurately represent the chemical formula and characteristics of the compound.
In inorganic chemistry, naming compounds often involves identifying the elements present and specifying their respective oxidation states or charges. Various naming conventions, such as the Stock system and the common system, are used depending on the type of compound and the specific elements involved.
Thus, the ideal selection is option C.

A science teacher asked students to calculate the density of a toy block. The mass of the block was 110 grams and the volume of the block was 8 cubic centimeters. What was the density of the toy block in cubic centimeters?
Answer:
13.75
Explanation:
Density is equal to mass divided by volume. 110/8 = 13.75
If a 50kg car is pulling a 30kg car, how much force would be required to accelerate the cars at 2m/s/s?
Answer:
160N
Explanation:
The force required to accelerate the two cars can be calculated thus:
F = m × a
Where;
F = force (Newton)
m = mass (kg)
a = acceleration (m/s²)
However, according to the question, a 50kg car is pulling a 30kg car, which means that the mass of the two cars is 50kg + 30kg = 80kg.
a = 2m/s²
F = ma
F = 80 × 2
F = 160N
A scientist thinks he found a new metal, so he published a paper about this metal. About 1 week after the scientist published the paper, you noticed a problem with the paper the scientist wrote. You noticed that this metal was not a new metal. In fact, this metal was discovered years ago. You determined this when you saw the atomic emission spectrum. As you read the article, you remembered that each atomic emission spectrum is unique to each element and the atomic emission spectrum matched one that was already discovered. Using the techniques from Chemistry, you ran a Flame Test with a piece of the metal (the metal is safe to use) that you had shipped to you. You found the metal turned the flame yellow. What metal did you have in your possession?
