ClO3− Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons. Show the formal charges of all nonhydrogen atoms, or use square brackets to denote the overall charge. View Available Hint(s)
Answers
Answer:
See explanation
Explanation:
The overall charge on ClO3− is shown on the image attached to this answer. If we calculate the formal charges on each atom in the structure, we will notice that one oxygen atom has a formal charge of -1 while all other atoms have a formal charge of zero.
This gives the compound an overall charge of -1 as shown in the image attached to this answer. This is the correct Lewis structure for the compound ClO3− .
The molecule has a formal charge of -1 on all oxygen atoms, and +2 on the Cl atom.
When all the electrons of an atom are shared equally, the charge attained by the atom is known as a formal charge.
The formal charge can be calculated as:
Formal charge = valence electron - non-bonding electron - [tex]\rm \dfrac{bonding\;electron}{2}[/tex]
In the molecule, the formal charge of Oxygen = -1.
In the molecule, the formal charge of Chlorine = +2
The oxygen atom has 8 electrons, in which 2 are shared in the bond formation, and 6 electrons are valence electrons.
The chlorine atom has 7 valence electrons in which 6 electron pairs are shared with the oxygen atom, and 1 lone pair has been available with Cl.
The structure of [tex]\rm ClO_3^-[/tex] molecule has been given in the image attached. The image shows the available lone pairs and the bonding in the structure.
Thus, the molecule has a formal charge of -1 on all oxygen atoms, and +2 on the Cl atom.

A 27.8 L balloon is filled with 7.52g of gas X and placed next to a 27.8 L balloon filled with helium.
Given that Helium has a density of 0.179g/L, which statement correctly explains the movement of the balloons
with valid justification?
a) The balloon filled with helium will float higher because helium is less dense than gas X
b) The balloon filled with gas X will float higher because gas X is less dense than helium
c) Both balloons will float to the same level because their densities are the same
d) Both balloons will float to the same level because their volumes are the same
e) There is not enough information to determine the movement of the balloons
Answers
Answer:
a) The balloon filled with helium will float higher because helium is less dense than gas X
Explanation:
Since gases are known to not have fixed density, they take up the density of their containers, let us find the density of the gas in first balloon.
Density is the mass per unit volume;
Density = [tex]\frac{mass}{volume}[/tex]
Insert the parameters and solve;
mass of gas = 7.52g
volume of the gas = 27.8L
Density = [tex]\frac{7.52}{27.8}[/tex] = 0.271g/L
Let us compare the two densities;
Density of gas = 0.271g/L
Density of helium = 0.179g/L
We see that the density of the gas is higher than that of helium, so, it not float as high as the balloon with helium. The balloon with helium is lighter.

Theresa creates an experiment where she mixes two red-colored substances together in a container and observes the solution slowly changing from red to blue for the next eight minutes. The solution becomes completely blue after eight minutes. What does this represent about the type of change happening in the container? A chemical change started immediately and finished at eight minutes. A non-chemical change started immediately and finished at eight minutes. A chemical change occurred at four minutes. A non-chemical change occurred at four minutes.
Answer:
A chemical change started immediately and finished at eight minutes.
Explanation:
A chemical change is one in which a new substance is formed. One of the indicators that a chemical change has occurred is the change in the color of the system from red to blue.
The question clearly stated that the change occurred gradually. This means that the reaction must have started immediately the substances were mixed and went on to conclusion after eight minutes when the complete blue color appears.

Answer:
The correct answer is - D) Eukaryotic cells.
Explanation:
The mitochondrion is found in all eukaryotic organisms with the exception of a few. It is a double-membrane-bound organelle within the cytoplasm of the cell that takes in nutrients, breaks them down, and creates energy that makes it the powerhouse of the cell.
It turns the chemical energy from nutrients in the cell to generate energy in a form usable to the host cell which is ATP. Prokaryotic cells lack mitochondria and other double membrane-bound organelles and it s found outside of the nucleus in the eukaryotic cells.

What will oxygen likely do to complete its outermost shell, based on the Lewis dot diagram shown?
accept electrons
accept some electrons and give up other electrons
move electrons from the inner shell to the outer shell
give up electrons
Answers
Answer:
A. Accept electrons
Explanation:
The octet rule states that 8 electrons stabilizes a molecule. This means that oxygen will try to fill the two empty spots with electrons from other molecules. The Lewis Dot diagram shows these two empty spots with the empty circles at the bottom.
Lewis dot structures, also known as electron dot structures, are schematics that show the interatomic chemical bonds in a molecule. Additionally, they show how many lone pairs there are overall in each of the atoms that make up the molecule. Here 'O' accepts electrons. The correct option is A.
The electrical structures of the elements, especially the electron pairings, are reflected in the Lewis dot structures. Lewis structures can be viewed as "electron bookkeeping" and are a helpful approach to condensing some bonding-related information. Each dot in a Lewis dot structure corresponds to 1 electron.
Group 6 member oxygen still requires two additional electrons to complete its outer shell and remain stable. According to the octet rule, an object needs 8 valence electrons in the outer shell to be stable.
Thus the correct option is A.

Maggie has 4 binders with 30 stamps in each binder. She has 3 binders with 36 baseball cards in each binder. If she gives away 45 stamps to a friend, how many stamps and cards does she have left? Maggie has stamps and cards left.
Answers
Answer:
The number of stamps and cards Maggie has left if she gives 45 stamps to a friend is 183
Explanation:
If Maggie gives 45 stamps to a friend, you must calculate the number of stamps and cards she has left.
You know Maggie has 4 folders with 30 stamps in each folder. So the number of stamps she owns is calculated as:
4 folders*30 stamps in each folder= 120 stamps
If Maggie gives 45 stamps to a friend, then the number of stamps she has left will be calculated as the difference (the subtraction) between the stamps she owned and the ones she gives away:
120 stamps - 45 stamps= 75 stamps
On the other hand, she has 3 binders with 36 baseball cards in each binder. So the number of cards she owns is calculated as:
3 binders * 36 baseball cards in each binders= 108 baseball cards
The number of stamps and cards you have left is calculated as:
75 stamps + 108 baseball cards= 183
The number of stamps and cards Maggie has left if she gives 45 stamps to a friend is 183

Anita was using steel to make rusted sculptures. After building each sculpture, she caused the steel in the sculpture to rust by placing it into a tub filled
with salt water for eight hours. Anita wondered if steel would rust faster submerged in vinegar instead of salt water. To find out, Anita cut ten squares of
steel sheet metal and split them into two equal groups. She put one group of squares into a tub filled with salt water and the other group of squares
into a tub filled with vinegar. Once an hour for eight hours, Anita counted the number of rusted steel squares in each group.
What is the manipulated independent variable in Anita's experiment?
Answers
Answer:
The type of liquid in the tub (salt water or vinegar)
Explanation:
The manipulated independent variable in Anita's experiment is the type of liquid in the tub.
The independent variable is the controlled or manipulated variable in the course of an experiment. It can also be referred to as the 'cause' variable which has the capacity to produce 'effects' on another variable - the dependent variable.
In this case, the type of liquid the tub is filled (salt water or vinegar) will hypothetically affect the rusting period of the steel. Hence, the dependent variable is the type of liquid the tub is filled while the dependent variable would be the time it takes for the steel to get rusted.
