In an ecosystem, deep, cold water is the  densest while warm, shallow water is the  least dense.

An ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Explanation:

Answer:

Explanation:

Answer:

sodium chloride

Explanation:

The bond type in the substance is ionic bonding because, ionic compounds in their solid state are not conducting but the ions they furnish when dissolved in water conducts electricity.

Ionic compounds are formed between metals and nonmetals. Metals are electropositive and they can easily loss electrons to from cations. Metals donate electrons to the electron deficient non metals to achieve octet.

Ionic bonding is a strong electrostatic force between opposite charged ions. Hence this bond is stronger than other types of bond. This intact bonding make them bad conductors in the solid state.

However they are electrically conducting the molten state or when dissolved in water due to the presence of free ions and electrons in the solution.

The number of atoms : N = 2.709 x 10⁴⁶

Given

4.5 x 10²² moles of CO₂

Required

The number of atoms

Solution

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

Input the value :

N = 4.5 x 10²² x 6.02 x 10²³

N = 2.709 x 10⁴⁶

Answer:

C: The reduction potential plus oxidation potential is negative

Explanation:

Redox reaction is a combination of reduction and oxidation reactions. A redox reaction can be nonspontaneous if the sum of reduction and oxidation potential is negative. Thus, option C is correct.

Redox reaction involves the transfer of the electron from an electron donor to an acceptor. This lead to the change in the oxidation number, and the charge on the atom or the molecules.

A redox reaction has been said to be nonspontaneous if the reduction and the oxidation half of the reactions add to a negative value. As there is an external voltage supplied to the reactants that have to result in a negative potential.

Therefore, option C. the redox reaction is nonspontaneous if the addition of the oxidation and reduction adds to a negative value is correct.

Colas are also carbonated beverages. The carbonation can produce some carbonic acid in the  Cola, which would affect your results. Therefore, to ensure that you are only titrating the  phosphoric acid you will use de-carbonated soda. This can easily be obtained by gently  heating the soda, or as you may already know, by rapidly shaking the bottle. It is also important that we do not use diet Colas since the artificial sweeteners that they contain have  acidic functional groups that will also interfere with the titration.

__________________________________________________________

Use a 25.00-mL pipet to deliver exactly 25.00 mL of room temperature, de-carbonated

Cola into a 250-mL beaker. Check out a magnetic stir bar and gently add it to the

beaker. Place the beaker on a stir plate. Set up a pH meter so that the probe is   completely immersed, but in a way that the stir bar will not hit it. The tip of the probe

has a thin glass membrane. Handle it with care! Position the beaker so that the stir bar

is as close to the center of the beaker as possible for optimal stirring. It should stir

rapidly enough to ensure thorough mixing but not so rapidly as to cause splattering.

__________________________________________________________

Obtain about 75 mL of 0.0100 M NaOH in a beaker. Use this NaOH to fill a buret.

Remember that you should always rinse a buret 2-3 times with the solution that you are

about to put into it and remove air bubbles at the buret tip. If you do not remember how

The initial level of the NaOH should be at exactly

0.00 mL. Once the buret is ready, place it over the beaker containing the Cola

Answer:

An orbit is a fixed path around the nucleus where an electron must be found; an orbital is a probability region where an electron is likely (but

not necessarily) going to be found

Explanation:

Orbits are fixed elliptical paths where an electron must be found. The idea of orbits was introduced in the Bohr model of the atom. Electrons were shown to occupy fixed orbitals of quantized energy.

Orbital is an idea introduced by quantum mechanics. It refers to a region in space where an electron may be found. The wave mechanical approach does not view the electron as being found in a fixed orbital but rather defines a region in space around the nucleus where there is a high probability of finding the electron.

Answer: Fish

Explanation:

Biotic factor is one of the component of the ecosystem. It is the living component of the ecosystem. It is affected or influenced by the non-living or abiotic components of the ecosystem like water, air, sunlight, and others. Fish is an example of biotic factor which is dependent on abiotic component that is oxygen which is the chief gas required for the breathing. The oxygen is one of the components of the water. So, the oxygen is dissolved in water and the fish acquire the oxygen through water only.

Answer:

Potassium

Explanation:

The atom with the largest atomic radius is potassium from the given list.

The atomic radius is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between nuclei in the solid metal state.

Across a period in the periodic table, atomic radii decreases progressively from left to right.

This is due to the progressive increase in the nuclear charge without an attendant increase in the number of electronic shells.

Answer:

Potassium

Explanation:

An atom's size is defined by the distance from the nucleus to the valence (outer) shell of electrons. Although difficult to to actually measure, due to electrons existing in a probability field with no defined boundaries, it is common knowledge that the more valence shells of an atom, the larger the atom.

Knowing this, lets look at the electron configuration of the elements mentioned:Oxygen = 2,6Sodium = 2,8,1Magnesium = 2,8,2Potassium = 2,8,8,2As we can see, only Potassium has four electron shells, therefore Potassium has the largest atomic size.Alternatively, one can look at a Van der Waal radii table to find that the radii of the four elements are (in picometres):Oxygen = 152 pmSodium = 227 pmMagnesium = 173 pm

Showing once again how Potassium has the largest atomic radius, and therefore the largest atomic size. Interestingly enough, Sodium has a larger atomic radius then magnesium, despite having less electrons and protons.
