what is the 3-dimensional orientation of a sublevel known as?
The 3-dimensional orientation of a sublevel is known as atomic orbital.
In quantum mechanics, Atomic orbitals are locations around an atom's nucleus where electrons are most likely to be at any particular time(specific orbits). These specific orbits exist in levels and can be broken down into sublevels.
Each sublevel has an orbital and it is oriented differently in 3-dimensional space.
The atomic orbital is a mathematical function that depicts how one or two electrons in an atom behave as seen in waves.

This name is made as follows:
The name of the metal is shown.The name of the non-metal is presented in abbreviated form.Add the suffix "ide" at the end.An example of this can be seen in the binary ionic composite KCL that receives the name Potassium Chloride, since potassium is the metal and chlorine is the non-metal.
It is important to remember that binary ion compounds are electrically charged ionic molecules formed by a metal and not a non-metal.

What could the class do to create the experiment?
A.
give all the pea plants the same amount of water and count the number of peas that the plants produce
B.
give all the pea plants different amounts of water and only guess the number of peas that the plants produce
C.
give all of the pea plants different amounts of water and count the number of peas that the plants produce
D.
stop watering all of the pea plants and then count the number of peas that the plants produce
Answer:
The answer would be C. Giving the pea plants a different amount of water in each one can help you observe how much water produces the most peas in a pea pod.
The answer is C to give all of the pea plants different amounts of water and count the number of peas that the plants produce
Explanation:
Answer:
C. give all of the pea plants different amounts of water and count the number of peas that the plants produce
Explanation:
The class wants to design an experiment that answers the question, "What amount of water will cause the plants to produce the greatest number of peas?"
To answer the question, the experiment should show how many peas the plants produce when they are given different amounts of water. The best way to do this would be to give all of the plants different amounts of water and count the number of peas that the plants produce.
What is the formula for this compound?
1 atom of copper, 1 atom of sulfur, 4 atoms of oxygen
Answer:
The third one: [tex]CuSO_4[/tex]
Explanation:
Again you are going to want to look at a periodic table so you can determine the symbol of each atom.
The symbol for copper is Cu, the symbol for sulfur is S and the symbol for Oxygen.
There is 1 atom of copper in the compound
So we have Cu
There is 1 atom of sulfur in the compound
So we would have CuS
There are 4 atoms of oxygen in the compound
So we would have [tex]CuSO_4[/tex]
Note that the little number at the bottom left after each symbol indicates how many atoms of that element are in that compound.
Consider the following system at equilibrium. CaCO3(s) Double headed arrow. Ca2 (aq) CO32â€""(aq) The addition of which compound will cause a shift in equilibrium because of a common ion effect? CCl4 CO2 CuSO4 Na2CO3.
The compound that has been capable to shift the equilibrium with common ion effect has been [tex]\rm \bold{Na_2CO_3}[/tex]. Thus, option D is correct.
The complete equation for the decomposition of calcium carbonate has been:
[tex]\rm CaCO_3\rightleftharpoons Ca^2^+\;+\;CO_3^2^-[/tex]
The equilibrium has been the state in the reaction, when the number of products and has been equivalent to the number of reactants. The increase or decrease in the concentration of any of the reactant or product results in the shift in the equilibrium.
For the given reaction, the addition of Calcium or carbonate ions to the solution results in the increase in the product concentration with the common ion effect, and thereby shifts the equilibrium condition.
The ions liberated by the following compounds has been:
[tex]\rm CCl_4\;=\text{not dissolved}\\CO_2\;+\;H_2O\leftrightharpoons CO_3^-\;+\;H^+\\CuSO_4\leftrightharpoons Cu^2^+\;+\;SO_4^2^-\\Na_2CO_3\leftrightharpoons 2\;Na^+\;+\;CO_3^-[/tex]
The compound, that has been capable of liberating the carbonate ions in the medium has been [tex]\rm \bold{Na_2CO_3}[/tex]. Thus, it results in the shift of the equilibrium due to common ion effect. Hence, option D is correct.

Which statement describes why sodium reacts more vigorously than magnesium to hydrochloric acid? Refer to the periodic table. Circle the letter of the correct answer.
1) Sodium has a smaller atomic radius than magnesium.
2)Sodium has a lower ionization energy than magnesium.
3)Magnesium has a lower ionization energy than sodium.
Answer:
Its B all the others arent true and also dont make any sense
Explanation:
Sodium has a lower ionization energy than magnesium describes why sodium reacts vigorously than magnesium chloride.
Why is sodium more reactive than magnesium?Sodium is more reactive than magnesium because it has the ability to easily lose electron, hence have lower ionization energy.Sodium belong to group one on the periodic table and they are called akali metal while magnesium belong to group two on the periodic table and they are called alkali Earth metal.Sodium and magnesium belong to the in the 3rd period. Iin the outermost energy level sodium has one electron but magnesium has 2 electrons. Therefore, there is more attraction abetween the nucleus and electrons in magnesium than that of sodium.Therefore, sodium is more reactive than magnesium chloride because of lower ionization energy.

How does the equation F= ma tell you that it is easier to push a small chair than a large couch
across the floor?
Explanation:
[tex] \boxed{ \mathsf{F = ma}}[/tex]
The Newton's Second law of motion, also known as The Law of mass and acceleration, derives the given equation in terms of mass, acceleration and force.
It actually states that Force applied on a body is equal to the time rate of change of it's momentum.
Momentum of a body, is the product of it's mass and velocity with which its moving.
This clarifies that objects at rest have zero momentum since they have zero velocity.
If a "source" applies force on an object, it's magnitude would depend on its rate of change of momentum with time.
Since, mass of an object is a fixed entity, so change in momentum would be caused due to change in velocity.
Now, if we happen to have two objects of different mass,
(As, in here, a chair and a large couch) and we have to push them so as to produce the same change in momentum, the force applied on a couch would be more than that applied on the chair.
Answer:This is simply because,
Force = mass × acceleration
If acceleration for both the objects is fixed, the force applied differs due to theur difference in mass.
Note here that Force I'd directly proportional to mass.
The greater the mass is, the higher is the force required to produce same acceleration.
Thus, objects with higher mass will require a greater amount of force to have the same acceleration as the object of light weight.
what are some negative impacts on the environment and society when the water cycle is disrupted and drought occurs ?
Some of the negative impact of disruption in water cycle are adverse environment, with affected farming, hydroelectricity, and deforestation.
The water cycle has been operated in the environment for the conversion of water in the different states. The water cycle has been operated with the conversion of water from the water body to the clouds by evaporation.
The evaporated water has resulted in clouds, that have been condensed and precipitated in the form of rain. The water cycle helps in maintaining the water balance in the ecosystem. It made the water available for use as well.
The drought has been the condition of the scarcity of water. In this condition, there has been a disruption of the water cycle. Some of the negative impacts resulting from the disruption of the water cycle are:
