The compound that forms between nitrogen and chlorine is
a. ionic
b. molecular/covalent
Answer:
Covalent bonding is a type of chemical bonding which is characterized by atoms sharing electrons. For nitrogen and chlorine to covalently bond, nitrogen needs 3 electrons. Chlorine only has one electron therefore two more chlorine molecules are needed. Because one atom of nitrogen needs 3 atoms of chlorine to bond, the formula will be NCl3.

A gardener cut her finger while pruning shrubs. She noticed that after two weeks the wounds had nearly healed with just a small scar remaining. Which statement describes what will happen next?
A. Each one of the individual cells near the wound will grow in size to cover the injured part.
B. Cells will be transported from distant areas to the wound to cover the injured area.
C. The cells near the wound will produce identical cells by mitosis to repair the damaged tissues.
D. A material will be released by the injured cells that will cover the wound and repair the cells.
Answer:
c
Explanation:
The wound will be healed by the production of new cells near the wound by the cell replication process and the therefore the identical cells are produced by the mitosis to repair the damaged tissues.
Note the below points about mitosis;
The mitosis is a process in which the cell replication occurs.In mitosis, the single parent cell is divided into two identical daughter cells by the process of cell division, it takes by time.The mitosis involves the healing of wound, growth of the organisms, replacement of the worn out cells.Thus, mitosis is the process involved in the healing of wound in living beings.
Therefore, we can say that the answer of the question is C. The cells near the wound will produce identical cells by mitosis to repair the damaged tissues.

“Nature vs. nurture” is a debate about
A
whether a trait is learned or inherited.
B
the traits of plants vs. the traits of animals.
с
whether animals can teach humans new traits.
D
whether a trait was acquired outdoors or indoors.
Answer:
Letter A
whether a trait is learned or inherited
Explanation:
The nature versus nurture debate involves the extent to which particular aspects of behavior are a product of either inherited (i.e., genetic) or acquired (i.e., learned) influences. Nature is what we think of as pre-wiring and is influenced by genetic inheritance and other biological factors.
The debate called Nature vs. nurture is about whether a trait is learned or inherited. This is an investigation on learned traits and nurtured traits in humans. Thus option A is correct.
What are learned traits ?All living things are learning something during their growth. These learning mold up one's personality and cannot be created by birth. Like the good characteristics we are learning from schools. These behaviors are called learned traits.
Some traits or behaviors are created by birth itself and they are called natural traits. The nature versus. nurture debate is a philosophical, scientific, and cultural discussion about whether human culture, conduct, and personality are largely influenced by nature or nurture.
Environment, culture, and experience are the most prominent definitions of nurture in this discussion, whereas nature is frequently regarded as genetic or hormone-based behaviors, characteristics, and dispositions.

You now have these half-reaction equations:
3e + HNO3 → NO
S→ H2SO4 + 6e
Which factor will you use for the top equation?
Which factor will you use for the bottom equation?
Explanation:
The two half equations are;
3e + HNO3 → NO
S→ H2SO4 + 6e
When balancing half equations, we have to make sure the number of electrons gained is equal to the number of electrons lost.
Which factor will you use for the top equation?
We multiply by 2 to make the number of electrons = 6e
Which factor will you use for the bottom equation?
We multiply by 1 to make the number of electrons = 6e

Explanation:
Most hot air balloons are round. Yes, you can have some other shapes like this one, but its shape is still rounded. Using the assumptions, explain why a square hot air balloon would be hard to make.
A square hot air balloon would be hard to make because the round shape of traditional hot air balloons allows for even distribution of heat, which is necessary to maintain the balloon's lift and stability.
What is a hot air balloon ?A hot air balloon is a balloon filled a heated air which can rise above the atmosphere. In a round balloon, the heat from the burner is evenly distributed around the circumference of the balloon, causing the air inside to heat up and rise, which in turn causes the balloon to lift.
If a hot air balloon were to be made in a square shape, the heat would be distributed unevenly and concentrated in certain areas. This could cause the balloon to become unstable, as the hot air would rise in some areas but not others, leading to uneven lifting and potential loss of control.
Additionally, the corners of the square shape would be more susceptible to damage and could create weak points in the structure of the balloon.
Therefore, while it is possible to create hot air balloons in other shapes, the traditional round shape has been found to be the most effective and efficient for maintaining the necessary heat distribution and stability required for safe and successful flight.

Calculate the mass of 5.22 mol of He.
Answer:
The mass is 20, 89 grams of He.
Explanation:
We calculate the weight of 1 mol of He, from the atomic weight of each element obtained from the periodic table: Weight 1 mol He= 4, 0020602 g. 1 mol He-----4, 0020602 g. 5,22 mol He---x= (5,22 mol He x4, 0020602 g)/ 1 mol He= 20, 89 g

The mass of 5.22 mol of He will be 20.84 grams.
We have 5.22 mol of He.
We have to calculate its Mass.
Which element is represented by symbol He ?Helium is a chemical element with the symbol He and atomic number 2. It is a gas which is colorless, odorless, tasteless, non-toxic, inert and monatomic.
According to the question -
Number of moles of Helium = 5.22 mol
Now, I mole of Helium will have its mass equal to its Atomic weight. Therefore -
Mass of 1 mole of He = 4.002602 g
So, the mass of 5.2 mol of He will be = 5.2 x 4.002602 = 20.84 grams
Hence, the mass of 5.22 mol of He will be 20.84 grams.

Calculate the volume occupied by 2.00 moles of H₂ at 300.0 K and 1.25 atm
Answer:
V = 39.38 L
Explanation:
Given that,
No. of moles of H₂, n = 2
Temperature, T = 300 K
Pressure, P = 1.25 atm
We need to find the volume occupied by the gas. We can use the ideal gas law to find it such that,
[tex]PV=nRT[/tex]
Where
R is gas constant, R = 0.08205 L-atm/mol-K
V is volume of the gas
Rearranging the above formula for V. So,
[tex]V=\dfrac{nRT}{P}\\\\V=\dfrac{2\times 0.08205\times 300}{1.25}\\\\V=39.38\ L[/tex]
So, the volume occupied by the gas is 39.38 L.
