Gravitational Potential energy:

The Gravitational potential energy of

an object at a point above the ground

is defined as the work done in raising

it from the ground to that point against

gravity.

Consider an object of mass "m" is raised

to heighth from the ground.

A force is required to do this. the

minimum force required to raise the

object is equal to the weight of the

object[mg]

The object gains energy equal to the

work done on it. Let the work done on

the object against gravity be "w"

WorkDone=W= Force x displacement

=mgxh

..W=mgh

since the workdone on the object is

equal to "mgh" an energy equal to "mgh"

units is gained by object.This is the

potential energy of object at height "h"

.. P.E=mgh

Answer:

Explanation:

Exothermic: the surrounds feel warmer. A wood fire stove is a good example of an exothermic reaction. You can feel the heat on your hands. It's exothermic.

Endothermic is exactly the opposite. The reaction takes place, but the heat comes from the surroundings. When you touch something that goes through an endothermic reaction, it feels much cooler.

This reaction, just by definition is endothermic.

Explanation:

The important thing to remember about reactions that involve gases kept under the same conditions for pressure and temperature is that the mole ratios that exist between the gases are equivalent to volume ratios.

This can be proven using the ideal gas law equation for two gases kept at a temperature

The problem tells you that this reaction takes place at constant temperature and pressure. You don't need to know the exact values, you just need to know that they are constant for all three chemical species.

You can thus say that since you have a

mole ratio between nitrogen gas and oxygen gas, you will also have a

Explanation:

1: Pioneer species are the first to colonize: During primary succession in lava on Maui, Hawaii, succulent plants are the pioneer species. After weathering breaks down the lava into the soil, the plants are able to take root. These plants will help to further change the soil by adding nutrients to it.

The first organisms to appear in areas of primary succession are often mosses or lichens. These organisms are known as pioneer species because they are the first species present; pioneer species must be hardy and strong, just like human pioneers.

Electrons

Explanation:

Isotopes are atoms which have the same number of protons and electrons but a different number of neutrons. This is also the reason why there are no other changes in the atom but the mass of the specific atom changes.

Hyperkalemia

Explanation:

The condition of acidosis can also cause Hyperkalemia because the higher H concentration diffuses to the ICF, pushing K towards the ECF.

Explanation:

NaOH + KNO3 --> NaNO3 + KOH. combustion. CH4 + 2 O2 --> CO2 + 2 H2O. single displacement. 2 Fe + 6 NaBr --> 2 FeBr3 + 6 Na. double displacement.

When perfume or cologne is sprayed into the air, it turns into a gas and its particles mix with other air particles that quickly move around the room. This is because gas is the least dense of the three states of matter. It moves quickly into any space or volume because it has the least density. This is called diffusion, when molecules or particles move from areas with high concentration to low concentration areas. 

Answer:

If it becomes buried deep into the earth and it is open to increased temperate and pressure. Then an Igneous rock could be Metamorphic. This process can take a lot of time but eventually the rock will change due to pressure andbhigher temperatures.

The statements which accurately describe the particles in differing states include:

Gases have the greatest kinetic energy which explains why its particles

move very rapidly and randomly when compared to other states of matter.

Conversion from solid to liquid or liquid to gas requires more energy being

added.

The particles in solids are tightly packed with very restricted movements

which is why they are able to vibrate at a place.

The three-dimensional coordination number of the face-centered cubic arrangement  has a coordination number of 12 and contains 4 atoms per unit cell.

The coordination number, also known as ligancy, of a central atom in a molecule or crystal is the sum of all the atoms, molecules, or ions that are linked to it. This value is used in crystallography and materials science. A ligand is the ion, molecule, or atom that surrounds the center ion, molecule, or atom.

The number of atoms, ions, or molecules that a central atom or ion bears in a complex or coordination compound or in a crystal as its near neighbors is known as the coordination number, also known as ligancy.

In contrast to oxidation state, which is a number assigned to an element in chemical combination and represents the number of electrons lost or gained by an atom of that element in the compound, co-ordination number is the number of co-ordination bonds with which the ligands are bound to the central ion.

Thus, the face-centered cubic arrangement  has a coordination number of 12 and contains 4 atoms per unit cell.
