ANSWER:

EXPLANATION:

Because according to Aufbaus principle,d orbital has less ENERGY than s orbital, hence it is WRITTEN first, hope you understood.

HEY DEAR HERE IS YOUR ANSWER ✌✌❤❤

K2Cr2O7 :- Potassium dichromate

Potassium dichromate in ACIDIC medium is a STRONG OXIDIZER. It means it gains electrons during redox reaction. Potassium dichromate in acidic solution results in :

K2Cr2O7+14H++6e−→2K++2Cr3++7H2O

Equivalent weight ofK2Cr2O7=

294.26/6

=49

This COULD have been the simplest answer.


HOPE IT HELPS U.✌✌

<STRONG>We know that In KMnO₄ the Mn CHARGE = +7,

On writing the reaction in acidic , neutral and basic medium.

(i)So reaction OCCURS in acidic medium :-

_______________________

MnO₄⁻ + 8 H⁺ + 5 e⁻ ----→ Mn²⁺ + 4H₂O

_______________________

As you see here , Mn gives up 5 e⁻ . (Making this as a strong oxidizing agent)

(ii) So reaction occurs in Neutral medium :-

_____________________

MnO₄⁻ + 4H⁺ + 3 e⁻ ------→ MnO₂ + 2H₂O

_____________________

As you can see here , In this neutral SOLUTION, it gives up 3 e⁻ in formation of MnO₂ & also some OH ions.

(ii) So reaction occurs in Basic medium :-

_____________________

MnO₄⁻ + e⁻ -----→ MnO₄²⁻

_____________________

As you can see here, it only gives up 1 e⁻ , So it makes it weaker oxidizing agent.

Hence we can simply observe here :-

MnO₄⁻ ion → Acidic solution > Neutral solution > Basic solution.

Hence it is strong oxidising agent in acidic medium.

Hope it Helps :-)

By USING DILUTION of SOLUTION.

BECAUSE THE HYDROGEN GAS IS IN GASIOUS STATE AND THE ALKALI METALS IS IS A METAL .SO WHEN H20 IS IN SMALL IN SIZE IT HAS HIGH IONIZATION ENERGY THAN ALKALI METALS.

It has tendancy to attract the SHARED pair of ELECTRON in a COVALENT BOND

The HEAVIEST PARTICLE is MESON

Water should not be used to CONTROL fire caused by ELECTRIC circuit becoz water is a good conductor of electricity so there is a chance that the PERSON who is putting water on it or who are standing nearby may recieve an electric shock
If the fire is caused by oil then too water is not apt for controlling it becoz oil floats on water as you know so water can spread the fire with the oil and fire still BURNING on it.
have a nice DAY

The TECHNIQUE of osmotic PRESSURE for determination of molar mass of solutes is particularly useful for BIOMOLECULES as they are generally not STABLE at high TEMPERATURES and polymers

Whenluciferin is EXPOSED to OXYGEN, a chemical reaction (aided ALONG by an enzyme called luciferase) EMITS light.

Because o-hydroxybenzaldehyde has LOW MELTING POINT

In copper and zinc the nuclear charge is less than SCREENING EFFECT so the ATOMIC radius INCREASES.

Being a highly electronegative atom in a periodic table, Fluorine (F) always possesses -1 OXIDATION state.

Due to HIGH electropositive nature, ALKALI metals LIKE Sodium (Na) only has +1 oxidation state.

While aluminium (Al) exist with various positive oxidation state because of its ease of acceptance of electrons to vacant d-orbitals.

Iodine (I) COULD exist in both the positive and negative oxidation states. The polarizability and electronegativity of iodine is responsible for the negative oxidation states like NaI, AgI etc whereas when iodine combines with higher electronegative atoms (oxygen, fluorine), it attains positive oxidation state. For example, IF5. The oxidation state of Iodine on IF5 is +5.

So Iodine (I) can exist in both positive and negative oxidation states.

Hey....hola! dear her here is your answer......☺️☺️

The O−O GROUP in a peroxide is called the peroxide group or peroxo group. In contrast to oxide ions, the OXYGEN atoms in the peroxide ion have an oxidation state of −1. A superoxide, ALSO KNOWN as hyperoxide,is a compound that contains the superoxide ANION with the chemical formula O2−.✌️✌️✌️✌️


hope it helps you.....ok....then bye

Processes which WORK together to perform MAINTENANCE job are called LIFE processes. I HOPE this HELP you

Due to the fact that they already have filled energy levels and zero VALENCE electrons so they are very stable and do not readily want to give up their electrons in chemical reactions as this would then LEAVE them more unstable again.

By definition, ionization energy is the amount of energy required to release an electron from an atom of the chemical in the gaseous PHASE. So a large amount of energy is required in the case of a noble gas in group 8 on the periodic table

's BLOCK ELEMENT are METALS and they have TENDENCY to lose eletron

Hey.....dear......here is your answer......✨✨✨✨



Liquids flow EASILY because the particles are able to move PAST each other easily. Gases can change shape and volume. ... Whether a substance is gas, liquid or solid DEPENDS on the balance between strength of its chemical bonds WITHIN its MOLECULES and the interactions between the molecules (inter-molecular interactions).❤️❤️

hope it helps you.....ok...bye,✌️✌️

Yyaa it GETS changed

pls MARK it as BRAINLIST

Hey....dear.....here is your answer.....☺️☺️

When an ELECTRON collides with an atom or ION, there is a SMALL probability that the electron kicks out another electron, leaving the ion in the next highest charge state (charge q increased by +1). This is called electron-impact ionization and is the DOMINANT process by which atoms and IONS become more highly charged.......✌️✌️✌️

hope it helps you.......✨✨✨

The rocky SURFACE of the is called CRUST and MAINLY made up of oxygen,silicon,aluminium,iron , calcium,SODIUM,potassium and MAGNESIUM

They are DIRECTLY PROPORTIONAL

HEY DEAR HERE IS YOUR ANSWER ✌✌❤❤

NaCl (COMMON salt) is SOLID in state and solid ions or COMPOUNDS don't conduct electricity. It needs to be either melted, molten or DISSOLVED in a solution (i.e. water) FIRST. This is because the electrons in a solid state won't be free to move to either the Cathode (-ve) or to the Anode (+ve). In a liquid state the electrons are free enough to move.

Thanks a lot. ✌✌

As the PH is decreasing (acidity increase ), the corrosion RATE is INCREASING. This is because low ph solutions accelerate corrosion by providing hydrogen gas.Hydrogen attacks and damage the surface of STEEL and increases the WEIGHT loss. Temperature also influences the corrosion rate.
