The Fe3+ ion is more STABLE than FE2+ because due to its electronic configuration i.e. the electronic configuration of Fe3+ has HALF - filled last orbital and we know that half or full filled orbitals are more stable and here Fe2+ has not half or full filled orbitals,so Fe3+ ion is more stable than Fe2+ ion.

here is your ANSWEREXPLANATION:Oxidation is the LOSS of electrons or an increase in the oxidation STATE of an ATOM, an ion, or of certain atoms in a molecule.

Na>Na+ Explanation:Na is Sodium atom ,where as Na+ is Sodium cation ( looses one electron and GETS positive charge) Na atom size is greater than Na+ Cation reason : in Na+ Cation the number of electrons are less than number of PROTONS in the NUCLEUS and due to this nucleus ATTRACTS more and shrinkage of Atomic size in Na+ cation takes place

When the market is in EQUILIBRIUM, there is no excess supply in the short run. ... Over TIME, the economy and EMPLOYMENT markets will SHIFT back into equilibrium as higher prices bring demand back down to normal run-rate levels.Explanation:PLEASE mark me as a brainliest

What are the FEATURES of a dynamic equilibrium?FORWARD and backward reactions occur at equal rates.Concentration of reactants and PRODUCTS REMAINS constant.

All three ions have the same NUMBER of electrons, but P3- has the FEWEST number of protons, so it has the LEAST POSITIVE nucleus out of the three atoms. Therefore, it will be the LARGEST.

Carbon has an ATOMIC MASS of approximately 12, and 1 mole of an atom weighs as much as the atomic mass of that ELEMENT in grams. Using that logic, 1 mole of carbon weighs approximately 12 grams, so 4 moles weighs approximately 48 grams.

Discovered: First ISOLATED by H. MOISSAN in 1886 after 74 years of efforts by various investigators (The UNKNOWN ELEMENT had been observed as a constituent of minerals.)

0.1Na2CO3 has the lowest MOLAR concentration among the given options. Therefore, option C is the CORRECT answer. Note : Normality can be DEFINED as the mole or gran number of EQUIVALENTS of the solute present in the one litre of the solution.Explanation:PLEASE mark me as a brainliest

O2Explanation:

Periodic TrendThe atomic radius of atoms generally decreases from left to right across a PERIOD. There are some small EXCEPTIONS, such as the oxygen radius being slightly greater than the nitrogen radius. ... SINCE the force of ATTRACTION between NUCLEI and electrons increases, the size of the atoms decreases.

Well, I don't know about the theory but here's the definition of it.Dynamic EQUILIBRIUM is the state of motion of a BODY under the INFLUENCE of several forceshope it helps!- ^ -

When all atoms/ions are in the same noble gas CONFIGURATION, then you would just compare the ratio of protons to ELECTRONS. Whichever has the highest proton/electron ratio would have the SMALLEST NUCLEUS. Therefore Ca2+ has the smallest nucleus while Cl- has the largest nucleus.

The size of an atom decreases from left to right. ... As the attractive forces become STRONGER, the electrons are drawn CLOSER to the NUCLEUS, and thus the atom is smaller. Li and Na are in the same group. As the ATOMIC mass increases as you move down the periodic table, Na has a larger atomic radius.

Rate of FORWARD REACTION and backward reaction are same and reactants and PRODUCTS are in their respective equilibrium concentrations.hope this will help you

In other words, K+ has bigger EFFECTIVE nuclear charge than Cl− , which TRANSLATES to a bigger net positive charge felt by the outermost ELECTRONS. This will compress the energy levels a bit and make the IONIC radius smaller for the potassium cation. THEREFORE, the chloride anion will have the larger atomic radius

Explanation:In a CHEMICAL reaction, chemical EQUILIBRIUM is the STATE in which both the reactants and products are PRESENT in concentrations which have no further tendency to change with time, so that there is no observable change in the PROPERTIES of the system

The N = 1 STATE is known as the ground state, while higher n states are known as excited states. If the electron in the atom makes a transition from a particular state to a LOWER state, it is LOSING ENERGY.

Catenation is the ABILITY of CARBON to FORM long chains. In fact, carbon ATOMS are unique because of catenation—they are unique among all of the other atoms found in nature. Now, carbon chains are FORMED because they form bonds, or tetravalent bonds, with other carbon atoms.

The VALUE of the mole is equal to the number of ATOMS in EXACTLY 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).

The amount of a substance that is REQUIRED to FORM a saturated solution in a given amount of solvent at a specified temperature. SOLUBILITY CURVE: A graph of the solubility of substances as a function of temperature.

tion:Mass PERCENTAGE of SOLUTION =( mass of solute ÷ mass of solution ) × 100 = (10 g ÷ 200 g )× 100 = 5 % . Therefore, the CONCENTRATION of the solution = 5% w/w.

lithium has the greater ATOMIC SIZE than NEON so it is LARGER

The Br− ion is SMALLER than the Se2− ion because the Br− ion has a LARGER nuclear charge and more EXTRA ELECTRONS than the Se2− ion. ... The Br− ion is smaller than the Se2− ion because the Br− ion has a smaller nuclear charge and more extra electrons than the Se2− ion.

Equilibrium is microscopically DYNAMIC but macroscopically STATIC. It means that microscopically the reaction ALWAYS goes on, i.e, the forward and backward reaction always goes on but they occur at equal rate. So macroscopically the CONCENTRATION of reactants and products stay same at equilibrium.I hope it HELPS you

The ground state is the state that is occupied by the most part of the atoms of the same ELEMENT at room temperature, because it is lower in ENERGY. ... For EXAMPLE, a simple six ELECTRON atom as the CARBON atom has the most stable electronic configuration represented by 1s² 2s² 2p².

Catenation (SELF linking of carbon atoms to FORM LONG chains) and Tetravalency are the two properties of carbon which lead to the formation of a LARGE NUMBER of carbon compounds.

A system in a steady STATE since forward reaction and BACKWARD reaction occur at the same rate. Supplement. In a dynamic EQUILIBRIUM, the rate of loss is equal to the rate of gain.Explanation:mark brainiest

tion:conductorsThey allow heat energy and electric currents to transmit through them with ease and SPEED. Conductors allow this transfer of energy to happen via free flow of ELECTRONS from atom to atoinsulatorStark opposite to conductors, insulators are materials that absolutely do not CONDUCT any electric energy or currents. They do not let any (or very little) electric charge flow through them. They have a significant band gap which prevents the flow of electricity. Some examples are glass, wood, plastics, RUBBER etc.semiconductorSemiconductors are the go-between conductors and insulators. These are solids that have the ability to conduct electricity through them but only under certain conditions. There are two such conditions that affect the ability of semiconductors to conduct energy, heat, and IMPURITIES.

Acetic Acid is an important chemical reagent and industrial chemical, USED primarily in the production of cellulose ACETATE for photographic film, polyvinyl acetate for wood glue, and synthetic FIBRES and fabrics. In households, diluted acetic acid is often used in descaling agents.I hope it HELPED you!! Thanks!!

tion:HISTORY is the study of the past. Events before the invention of writing SYSTEMS are CONSIDERED prehistory. "History" is an umbrella term COMPRISING past events as WELL as the memory, discovery, collection, organization, presentation, and interpretation of these events.
