r !!Answer:Acids and acidityHydronium is the cation that FORMS from water in the PRESENCE of hydrogen ions. These hydrons do not exist in a free state - they are extremely REACTIVE and are SOLVATED by water. An acidic solute is generally the source of the hydrons, but HYDRONIUM ions exist even in pure water.

is 29TH ELEMENT in PERIODIC table

tion:Ionization energy is the amount of energy required to remove an electron from neutral gaseous ELECTRONS .Across period, in a periodic table from left to right I.E should increase.Third period elements are :Na, Mg, Al, Si, P, S , Cl, ArOrder of I.E in third period:NaAlAl due too its stable ns2 configuration of Mg.Case 2:P has more I.E than sulphur (S) a because phosphorous has half FILLED p sub SHELL in its valence shell that gives EXTRA stability and hence more energy is required to remove the electron.MARK.

yes VANDER wall RADIUS>covalent radius of iodineExplanation:(1)covalent radius is half of intra atomic distance but vander wall RADII is half of inter molecular distance.(2)inter molecular distance >intra atomic radius due to large size of iodine there are less ATTRACTION between iodine molecule and ALSO due to non polar molecule

The REACTANTS are STRONGLY heated.By calcination-CuS --> Cu + SHgS --> Hg + SBY roasting -ZnCO3 --> ZnO + CO2

The 'temperature of a substance' remains constant during its melting and boiling point because the CHANGE in any STATE of matter as N solid to liquid or the liquid to a gas INVOLVES crossing the 'latent heat of fusion' which CAUSES a change in the intermolecular spacing of the molecules in the substance.

There's a good chance you punctuate poorly and don't realize it.This page will fix your mistakes. It covers the TOP ten rules of punctuation.But LET's first CONSIDER why you should care about ♖ Good writing is an indicator of an organized mind that is capable of arranging INFORMATION in a systematic fashion to help other people understand things. — Dustin J. Mitchell♖ Clear writing leads to clear thinking. You don’t know what you know until you try to express it. — MICHAEL A. Covington♖ If you are deciding between two people to hire, always choose the better writer. Assuming they are equally qualified, the better writer will communicate work issues more clearly. This extends to emails, messages — frankly, everywhere. — David Heinemeier Hansson

have the ions (cations- +ve CHARGE and electrons -ve charge) packed closely by forces of attraction. Thus the lattice structure is quite packed as shown here: You get a pretty solid structure with almost no AIR GAPS between. Thus the HIGH density.pl MARK Brainly bhai bhen pl pl

MARK IT AS BRAINLIEST ❤1.when tea is poured into a saucer when it is very hot it is EXPOSED to a large area and causes evaporation n the tea becomes cool.2.In summer seasons the water gets cool in a earthen pot because it has fine pores in it through which water SEEPS out gets evaporated .when we sweat n sit under a fan we feel cool.3.During the summer, we wear cotton clothes. Cotton, being a good absorber of water allows more sweat to be in contact with the atmosphere, consequently helping in more evaporation. It is for this reason that we feel cooler when we wear cotton clothes.4.Especially in villages,PEOPLE often sprinkle water on the ground in front of their homes during hot summers.5.Put a little of spirit on your hand and wave around, the spirit evaporates rapidly and our hands FEELS cooler.HOPE IT HELPS ♡

An oxidation-reduction reaction, or redox reaction, is a chemical reaction in which one or more ELECTRONS are transferred from one molecule or compound to another. The species that loses electrons is oxidized and USUALLY a reducing agent; the species that GAINS electrons is reduced and is usually the oxidizing agent. EVERYDAY redox reactions include PHOTOSYNTHESIS, respiration, combustion and corrosion.

The electrons in the s - ORBITAL are more attracted towards the nucleus than P - orbital electrons. Hence they WOULD have higher Ionisation Enthalpy and hence difficult to remove. MOREOVER s - orbital can accommodate only 2 electrons. In 2S2 condition the orbitals are fully filled. It’s also difficult to remove electrons from fully filled stable orbitals.

re microscopic!!Noo! We cannot see them with our EYES! *they are extremely small measuring about 1 X 10-10 METERS in diameter. !!

A heterogeneous mixture is a mixture with a non-uniform COMPOSITION. The composition varies from ONE region to another with at least two phases that remain separate from each other, with clearly identifiable properties. If you examine a SAMPLE of a heterogeneous mixture, you can see the separate components.

Solid oxygen FORMS at normal atmospheric PRESSURE at a TEMPERATURE below 54.36 K (−218.79 °C, −361.82 °F). Solid oxygen O2, like LIQUID oxygen, is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light SPECTRUM.

fh° (fe2o3) = -824 kj/mol, ∆fh° (co) = -110 kj/mol, ∆fh° (co2) = -393 kj/mol​To FIND:Calculate standard enthalpy of reaction fe2o3+3co=2fe+3co2 from the following data.Solution:From given, we have,∆fh° (fe2o3) = -824 kj/mol, ∆fh° (co) = -110 kj/mol, ∆fh° (co2) = -393 kj/mol​we use the formula,∆fh° = [2 ∆fh° (fe) + 3 ∆fh° (co2)] - [1 ∆fh° (fe2o3) + 3 ∆fh° (co)] ∆fh° = [2 (0) + 3 (-393)] - [1 (-824) + 3 (-110)] ∆fh° = [0 - 1179] - [-824 - 330] ∆fh° = - 1179 - [-1154] ∆fh° = - 1179 + 1154∴ ∆fh° = - 25 kJ/molTherefore, the standard enthalpy of reaction fe2o3+3co=2fe+3co2  is - 25 kJ/mol
