Valence Shell Electron Pair REPULSION Theory (VSEPR) is a molecular MODEL to predict the geometry of the ATOMS making up a molecule where the electrostatic forces between a molecule's valence electrons are MINIMIZED around a central atom.Oct 10, 2019Explanation:please MARK me brainlist

John DaltonThe present chemical symbols express the SYSTEMATIZING of CHEMISTRY by the atomic theory of matter. The English CHEMIST John Dalton, who followed the alchemists in representing the elements pictorially, made the important advance of LETTING his symbols designate single atoms of elements, not indefinite amounts.

7.874 g/cm³ (NEAR ROOM TEMPERATURE) is the DENSITY of IRON.

When 0.0976g of MAGNESIUM was heated in AIR, 0.1618g of magnesium OXIDE (MgO) was produced. What is the mass of OXYGEN needed to PRODUCE 0.1618g MgO?

Hope its Helpful to YOUPLEASE FRIEND me MARK as Brainliest ANSWER plzIt's a Humble REQUEST to you

Hiiiiiiiiiiiiiiiiiiiiiiiiiiiii

Let the density be x g/CM 3 .So, volume of x gm of H 2 at STP is 1000 cm 3 .Therefore, volume of one mole (2.016 gm) of GAS = x1000 ×2.016 cm 3 ⇒C P −C V =R= TPV ⇒150= x×2731.013×10 5 ×1000×2.016×10 −3 ⇒x=4.99 kg/m 3Explanation:please MARK me brainlist

Explanation:l=1 , so it MUST be a p- orbital.since n=3 ,So it must be a 3p -orbital.now m= -1 so it is 3PX or 3py.It cannot be 3pz as for z-orbital z= 0.

Given conditions,Carbon % = 76.5%HYDROGEN% = 6.38%OXYGEN% = 100 - (76.5 + 6.38)  = 100 - 82.88  = 17.12%Now, Refers to the attachment for the Empirical Formula Chart.Empirical Formula is C₆H₆O.Empirical Formula Mass = 12 × 6 + 1 × 6 + 16 = 94 gMolecular Mass = 2 × Vapor Density∴ MOLECULAR Mass = 2 × 47∴ Molecular Mass = 94 g.∴ n = Molecular Mass/Empirical Formula Mass   = 94/94   = 1∴ Molecular Formula = 1 × C₆H₆O   = C₆H₆OHope it helps.

rogen bond is one of the STRONGEST intermolecular attraction, but WEAKER than a covalent or an IONIC bond.plz follow me I follow U BACK

because when water boil in PRESSURE cooker,RHE pressure cooker does not ALLOW the evaporated steam to go out so the temperature of water and the steam present in the combine and the temperature increase 120'C

tion:QUESTION 1. Carbon has 6 ELECTRONS.so,1s*2 ,2s*2 2p*2Sodium has 11 electrons.so,1s*2, 2s*2 2p*6, 3s*1QUESTION 2.as k shell has 2 electrons and L shell has the tendency of 6 electrons so, total electrons will be 8.question 3 is not complete.mark as brainliest as I also gave explanation that how I solved.......!

Two primary alkyl halides with molecular formula C 4 H 9 Br are possible. They are n-butyl bromide and isobutyl bromide.When (a) is REACTED with sodium metal it gives compound (d), C 8 H 18 which is DIFFERENT from the compound formed when n-butyl bromide is reacted with sodium. Hence, compound a is isobutyl bromide and compound d is 2,5-dimethylhexane.2CH 3 CH 2 CH 2 CH 2 Br+2Na Wurtz reaction CH 3 CH 2 CH 2 CH 2 CH 2 CH 2 CH 2 CH 3 (n−octane)2CH 3 CH(CH 3 )CH 2 Br+2Na wurtz reaction CH 3 CH(CH 3 )CH 2 CH 2 CH(CH 3 )CH 3 (2,5−dimethylhexane)(a) reacted with alcoholic KOH to give compound (b).CH 3 CH(CH 3 )CH 2 Br alcKOH CH 3 C(CH 3 )=CH 2 (2−methyl−1−propene)Compound (b) is reacted with HBr to give (c) which is an isomer of (a).CH 3 −C(CH 3 )=CH 2 HBrMarkownikoff ′ s rule CH 3 −CBr(CH 3 )CH 3 (tert−butylbromide)Explanation:please mark me brainlist
