Prokaryotic and Eukaryotic Cells Booklet

Answer:

D. see which items stick to the magnet

Explanation:

To predict which items are magnetic, the students will have to test whether or not each item is attracted to the magnet. Only objects that are magnetic stick to a magnet, so all of the items that stick to the magnet should be magnetic.

Hopefully that's helpful! :)

C.)Air is made up of atoms of one elements

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.

Explanation: The elements in the modern periodic table are arranged in order of their atomic numbers, which is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number.

Explanation:

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Answer:

photosynthesis is the process of making food by green plants by using sunlight,carbon dioxide, water.

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.

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.

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.

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:

Desert environment will probably have the lowest relative humidity.

Relative humidity is a measure of water vapor content in the air. Desert environment will have the lowest relative humidity due to its high temperature and no availability of water bodies such as river, ocean etc so we can conclude that desert environment will probably have the lowest relative humidity.

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.

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.

To name the binary ionic compounds it is necessary to observe which is the metal and the non-metal that compose them.

This name is made as follows:

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.
