nsition metals are compounds that form at least 1 stable ION where the compound has an incomplete d subshell. Therefore, SCANDIUM is not a transition metal, because it forms only Sc3+ ions with n d-ELECTRONS, and ZN is not a transition metal because it forms only Zn2+ ions with all the 3d electrons PRESENT. Transition metals form a transition between the properties of group 1 and 2 to the properties of group 3 and 4.

pressure of the GAS contained in a closed vessel is increased by maybe UR question is INCOMPLETE

.5thank you...

the QUESTION????

e!!! here is your ANSWER the atomic RADII of hydrogen is 53 pm

t INSTEAD of UMBRELLA

are zinc sulphate SOLUTION and immerse a COPPER plate in it.B. NONE of these because aluminium hydroxide is insoluble in water.C. Less reactive then aluminiumD. Colourless

. CO(II)I just checkedConfirmed

when FeSO⁴ is HEATED than Fe²O³ on,SO²and SO³ is released .NATURE of SO² is ACIDIC so blue TURNS into red

TE !!!HOPE THIS HELPS YOU...(i) Mass of the atom excludes mass of ELECTRON since electron has very small mass I.e, me = 9.1 × 10^(-31) kg .It is in terms of 10^(-31) which is very NEGLIGIBLE.(ii) Nucleus CONSISTS of Proton and NEUTRONS which are positively and neutrally CHARGED respectively ,but Nucleus does not constitute of electron hence it is positively charged.THANK YOU FOR THE WONDERFUL QUESTION...#bebrainly

SODIUM CARBONATE:The main uses of sodium carbonate are as water softener, food processing AID, PH modifier, swimming POOL chemical and electrolyte. It is also used in the manufacture of glass, paper, SOAPS and detergents, and MANY other useful chemicals.hope it helps ♡♡

/2h2o..Hope it HELPS you my DEAR FRIEND.. Please MARK my answer as BRAINLIEST.. ✌❤

he scale USED to identify it is acidic or BASIC in aqueous solution.. Ph value of WATER is 7..Hope it HELPS you my DEAR friend.. Please mark my answer as brainliest.. ❤✌

your ANSWER mate✌️✌️

MATE ❤️❤️❤️ HERE IS UR ANSWER....HOPE THIS WILL HELP YOU ❤️ ❤️STAY BLESSED ❤️ ❤️❤️

.❤❤❤here is ur answer...Thermal EquilibriumTwo systems are said to be in thermal equilibrium if the temperatures of the two systems are equal. In mechanics if the NET force on a system is zero, the system is in equilibrium.  In Thermodynamics equilibrium means all the macroscopic variables (pressure, temperature and volume) don’t change with time. They are CONSTANT throughout.For Example: -Consider two bodies at different temperatures one is at 300C and ANOTHER at 600C then the heat will flow from body at higher temperature to the body at lower temperature.Heat will flow till both bodies acquire same temperature.This state when there is no heat flow between two bodies when they acquire the same temperature is known as thermal equilibrium. In the above case if consider a hot cup of COFFEE will become cold after sometime if it is kept on the table as there will heat flow between the hot coffee and surroundings. When the cup of coffee attains the same temperature as of room temperature then there will be no flow of heat.hope it helps...plzz mark me as brainliest my dear !!!❤❤❤

a very sensitive and accurate balance.✴It is a device used to FIND accurate measurements of weight.✴The object to be MEASURED is placed on the bottom and the weight can be read on the screen. ✴As this balance is very sensitive and accurate, it is used in laboratories and in a jeweller's and grocer's shop.✴The basic unit of weight is gram measured by this device. It balances to a measure of 2 decimal places accuracy meaning to the nearest 0.01 gConversions applicable to electronic balance✍1 gram = 1000 milligrams => 1000000 micrograms ✍1 MILLIGRAM = 1000 microgram => 0.001 gram

⤵these are the groups which DECIDED the physical and CHEMICAL PROPERTIES of Atom or molecule....✔✔hope it helps ❤❤

is not POSSIBLE ... OKK

ctivity SERIES is a series of metals, in order of REACTIVITY from HIGHEST to lowest. It is used to determine the products of single displacement reactions, whereby metal A will replace another metal B in a SOLUTION if A is HIGHER in the series.

it is a SMOG that COMES from the ultraviolet RAYS of the sun. I guess

law of ocatves was found to be applicable only till calcium2. He thought that there are only 56 elements and no more elements WOULD be found in the near future. 3. In order to fit the elements he add TWO elements in one slot and also adjusted some UNLIKE elements under the same note.4. Iron having simlilar PROPERTIES of cobalt and nickel is placed far away from them.

the REQUIRED answer.HOPE IT HELPS!!!

helpspls MARK it as the BRAINLIEST ANSWER :)

now that, the more negative the electrode potential GREATER is the reducing POWER of the electrode. The HIGHEST oxidation state for Cr is +6, therefore it can loose 3 more electrons, whereas FE needs to loose only 1 electron to achieve its highest oxidation state of +3. Thus, Cr3+ is more reducing than Fe2+.

m ionic BONDS, Carbonmolecules must either GAIN or lose 4 electrons. This is HIGHLY unfavorable; therefore, carbon molecules share their 4 valence electrons through single, double, and triple bonds so that each atom can achieve noble gas configurations.HOPE IT HELPS UH!
