Because COLOUR depends on d orbitals of atom. QHICH is PHYSICAL PROPERTY

This rapid discharge of the earth's store of ORGANIC energy fuels the human domination of the biosphere, including CONVERSION of NATURAL habitats to agricultural fields and the RESULTING loss of native species, emission of carbon dioxide and the resulting climate and sea level change, and use of supplemental nuclear.

A CHEMICAL property can be DETERMINED only when a change in the substance occurs in the PRESENCE of another substance or when sufficient ENERGY of some FORM is added to it .

nal group :-⇰ It is defined as an atom or group of atoms joined in a specific manner which is RESPONSIBLE for the CHARACTERISTIC chemical properties of the ORGANIC compounds.For EG:-Hydroxyl group (—OH)Aldehyde group (—CHO)

n=5 MEANS it is the fifth electron shell. 'l' is the azimuthal quantum number and it describes electron subshell (s,p,d ETC.). Basically, l=0 corresponds to s ORBITAL, l=1 – p orbital, l=2 – d orbital and l=3 – F orbital. So, the final NOTATION is 5f.

In general rich sources of magnesium are greens, nuts, seeds, dry BEANS, whole grains, wheat GERM, wheat and oat BRAN. EXPLANATION:hope it helps.pls mark me as brainliest.pls

BRITTLEExplanation:The widespread use of magnesium is hampered by its INTRINSIC brittleness. While other metallic alloys have multiple DISLOCATION slip systems, enabling their well-known ductility, the hexagonal LATTICE of magnesium offers insufficient modes of deformation, rendering it INTRINSICALLY brittle.Hope it helps.pls mark me as BRAINLIEST.

In the HUMAN body, equilibrium PLAYS a prominent role in regulating the concentrations of various SUBSTANCES, notably pH, in the bloodstream. Maintaining a level pH is vital for human survival because enzymes and PROTEINS both rely on pH to FUNCTION properlyExplanation:mark brainiest

Static equilibrium is a valuable analysis TOOL: for example, if two forces are acting on an OBJECT that is in static equilibrium, that means they add up to zero. If you know the direction and magnitude of one of the forces, you can write an EQUATION to determine the magnitude and direction of the unknown forceExplanation:mark BRAINIEST

it will be has a hydrotbond

tion:The orbital having N = 5 and l = 3 is 5f. NOTE: Here n ( principal quantum NUMBER ) represents 5TH electron shell. and l ( azimuthal quantum number) represents F subshell.

tion is a force between two surfaces that are SLIDING, or trying to slide, across each other. For example, when you try to push a book along the floor, friction makes this difficult.Friction always works in the direction opposite to the direction in which the object is moving, or trying to move. Friction always slows a moving object down.The amount of friction DEPENDS on the materials from which the two surfaces are made. The rougher the surface, the more friction is produced. Friction ALSO produces heat. If you rub your HANDS together quickly, you will feel them get warmer.

n :-Three properties of Magnesium are :-It is a silvery-white METAL that ignites EASILY in air and burns with a bright light. It is one-third LESS dense than aluminum.It has the lowest MELTING (923 K) and the lowest boiling point (1,363 K) of all the alkaline EARTH metals.Remarks :-Hope u liked my solutionPls mark me as brainliestThanks.

Physical EQUILIBRIUM is defined as the equilibrium which DEVELOPS between different phases or physical properties. In these PROCESSES, there is no change in chemical composition. It represents the existence of the same SUBSTANCE in TWO different physical statesExplanation:mark  hrainiest

Explanation:Magnesium makes up 2 percent of the Earth's crust, but you won't see this silvery, light metal in nature. This versatile element occurs naturally only in combination with other elements, such as carbon, calcium and oxygen, as in the common MINERAL dolomite.The metal can be mixed with other metals, PARTICULARLY aluminum, for use in making CAR bodies, drink cans and other items that need to be light and strong. Magnesium is flammable, so ONE of its main uses is for flares and fireworks. During World War II, the element was even used to make incendiary bombs.Its Atomic symbol (on the Periodic Table of Elements): MgMagnesium also has biological uses. It's part of chlorophyll, the green pigment that plants use to extract energy from sunlight. The element is also crucial to more than 300 biological processes in the human body.Fruits, vegetables, nuts, legumes and whole grains are good sources. Doctors sometime recommend magnesium supplements for a variety of medical conditions, including high blood pressure, premenstrual syndrome and diabetes.            hope it HELPS :)

The atom that will have a larger radius than zinc is strontium, Sr. Atomic radius is defined as the HALF of the inter-nuclear distance between TWO covalently BONDED atoms of non-metallic elements or half of the distance between two NUCLEI in the solid state of metals.

yes CARBON have 4 ELECTRON on OUTSIDE SHELL

There are THREE TYPES of equilibrium: STABLE, UNSTABLE, and neutral.

Carbon makes 4 ELECTRONS to FORM a covalent bond.It has a number of allotropes and other forms of existence. Carbon is HIGHLY UNREACTIVE under conditions which are NORMAL.

definition~⇰ Ionic COMPOUNDS or ELECTROVALENT compounds have a STRONG electrostatic force between their atoms DUE to the unlike charges of their ions which makes the bond stronger not easy to BREAK, thus ionic compounds are solids.Urdu definition~آئنک مرکبات یا الیکٹروالینٹ مرکبات ان کے آئنوں کے برعکس چارجز کی وجہ سے اپنے ایٹموں کے درمیان ایک مضبوط الیکٹرو سٹاٹک قوت رکھتے ہیں جس کی وجہ سے بانڈ مضبوط ہوتا ہے توڑنا آسان نہیں ہوتا ، اس طرح آئنک کام

Explanation:i] Magnesium is used in products that BENEFIT from being lightweight, such as car seats, luggage, laptops, cameras and power toolsii] It is ALSO added to molten iron and steel to remove SULFUR. iii] Magnesium is most commonly used for constipation, as an antacid for heartburn, for low magnesium levels, for pregnancy complications called pre-eclampsia and eclampsia, and for a certain type of irregular heartbeativ] The green leafy VEGETABLE is an excellent source of Magnesium. Whole grain, seeds, and nuts (Mainly almonds) are also a great source of Magnesium.v] The FLASHBULBS also contain Magnesium. When Mg burns, it produces a bright light that helps the photographers to take photos in the dark.hope it helps :)

Keq = [C] × [D] / [A] × [B] EXPLANATION:This EQUATION is called equation of law of chemical equilibrium. At equilibrium, the concentration of REACTANTS is expressed as moles/lit so Keq = KC and if it expressed as partial pressure then Keq = KP.

When a body remains in the same state of motion (translational or ROTATIONAL). under the influence of the applied forces. the body is said to be in DYNAMIC EQUILIBRIUM. For example. a raindrop reaches the EARTH with a constant velocity is in dynamic equilibrium.

Growth rates within ORGANS become equal. (2) The organism BECOMES ill or may die. (3) A constant sugar supply for the CELLS is produced.

Respiration is the process in which the CELLS of an organism OBTAIN ENERGY by combining oxygen and glucose, resulting in the release of CARBON dioxide, water, and ATP (energy).Explanation:
