HEY MATEExplanation:Transition metals exist in HCC geometry in which there is vacant spaces. In these vacant spaces the elements like C, H & O forms compounds called interstitial compounds.II) Due to lanthanide contraction, the METALLIC radii of the third (5D) series of transition metals are virtually the same as those of the CORRESPONDING group members of the seconds (4d) series."The steady decrease in the values of the radii of M 3+ cations in the lanthanide series is called as Lanthanide contraction."III) This is because of the compareble energies of 5f, 6d and 7s orbitals so all of them can participate... hope it helps uh..@tripathipriya

because AL REACTS with some other SUBSTANCES

omate ion (CrO42−) has a tetrahedral shape, WHEREAS dichromate ion has two tetrahedral units with one COMMON oxygen having Cr−O−Cr BOND angle of 126o.i hope this answer helps..mark me as a BRAINLIEST..

Amount of water produced by the combustion of 16g of methane is: ACCORDING to the above equation, ONE mole of CH4 (16 g) on combustion gives one mole of carbon dioxide and 2 moles of water and 2 moles of water = 2 x [2 + 16] = 36 g of water.

In simple common LANGUAGE, evolution of GAS means coming out of any gas when a chemical reaction takes PLACE.

oys of transition METALS are hard and high metals are high MELTING as compared to the HOST metal. Various steels are alloys of iron With metals such as chromium, VANADIUM, molybdenum, tungsten, manganese etc.✔️✔️✔️

The contact process is the CURRENT method of PRODUCING sulfuric acid in the high concentrations needed for industrial processes. Platinum used to be the catalyst for this reaction; however, as it is susceptible to reacting with ARSENIC impurities in the SULFUR FEEDSTOCK, vanadium(V) oxide (V2O5) is now preferred.

tion:The numbering will start from ETHYL group in left and end on the RIGHT ethyl, you can ALSO expand the C2H5 to CH3CH2

Most of the TRANSITION ELEMENTS SHOW PARAMAGNETIC BEHAVIOR.

pentantriol is the RIGHT ANSWER. REFER ATTACHMENT!!

Transition metals SHOW variable O.S due to incomplete orbital E.Configuration. In transition metals all d-orbitals are never fully filled , they left incomplete . Due this this they exhibit variable O.S. The stable O.S of transition metals is =+3 They even range from +1 to /+8/+9 and so on . The metal carbonyls like NICKEL tetracarbonyl show NI in zero O.S. Their variability is unique among all blocks . If we compare with p-block elements , the variability is not so range as in transition metal. For EXAMPLE Mn=+2/+3/+4/+5/+6/+7 Cr=+3/+4/+5/+6. Os=+3——-+8. However in case of p-block such range of variability is lagging BEYOND. Here the p orbitals are not so much incomplete like in transition.Explanation:

when the ACID REACT with METALS (metals are basic in nature) they form salt+hydrogen

tion:Friedel Crafts alkylation reaction: When BENZENE is treated with alkyl HALIDE in the presence of a Lewis acid such as anhydrous aluminium chloride, alkyl benzene is formed. This reaction is POPULARLY known as Friedel Crafts alkylation reaction.Friedel Crafts acylation reaction: When benzene is treated with acyl halide in the presence of Lewis ACIDS such as anhydrous aluminium chloride, acyl benzene is formed. This reaction is popularly known as Friedel Crafts acylation reaction.

Vinegar is STRONG acid (acetic acid) and it lowers pH of JARRED food materials when added for PICKLING. Very few BACTERIA can GROW in low pH, hence vinegar helps in preservation.Explanation:

Density of an element is equal to mass/volume.The f block elements have high mass but their SIZE does not increase much due to poor SHIELDING. THEREFORE, the f-block elements have high density.

♪➡️Here you go :-↘️Lattice structures are topologically ordered, three-dimensional open-celled structures composed of one or more repeating unit cells [2,3]. These cells are defined by the dimensions and connectivity of their constituent strut elements, which are connected at specific NODES.(*'▽'*)♪EXTRA:-For example, the SET {0, ½, 1} with its USUAL ordering is a bounded lattice, and ½ does not have a complement. ... A bounded lattice for which every element has a complement is called a complemented lattice. A complemented lattice that is also distributive is a Boolean algebra.I HOPE it helps you!!!

he use of Felling's solution. Propanal being an aldehyde reduces Fehling's solution to a red-brown precipitate of Cu2O, but propanone being a KETONE does not. ii) By using the Iodoform test. Benzophenone does not contain any free methyl group so it will give a negative test. Benzophenone + Sodium Hypoiodite → No YELLOW ppt of CH₃.iii) By warming with sodium hydrogen carbonate. Benzoic acid gives effervescence hence producing CO2 gas while ethyl benzoate does not RESPOND to this test. iv) Iodoform test To carry out a positive iodoform test, it is necessary to have a methyl ketone or methyl alcohol.I hope it REALLY helps... ❤
