riend your ANSWER is here ✌Cesium and GALLIUM....will MALT if they are KEPT on our palm of hand...Thanks ☺

are MIXTURES because the ELEMENTS that MAKE it up are physically together, not CHEMICALLY joined together as in a compound.

dioxide is a GAS. It is invisible and has a nasty, sharp smell. It reacts easily with other substances to form HARMFUL COMPOUNDS, such as sulfuric acid, sulfurous acid and sulfate particles. About 99% of the sulfur dioxide in air COMES from HUMAN sources

ears BLUE during NOON because of the REFLECTION of light from the seas.

monoxide, CO, is a ubiquitousligand in organometallic and coordination chemistry. ... HOWEVER, these polar ligands are therefore also more REACTIVE; and more sensitive, e.g. to nucleophilic attack, because of a low-energy 2π LUMO. Our results SUGGEST that BF and SiO should, in principle, be excellent ligands.hope it will help you.

⤵⤵⤵⤵hi buddy here is your ANSWER....INTERSTITIAL hydrides which are ALSO called metallic hydrides are those in where the oxidation NUMBER of hydrogen is zero. PALLADIUM, Uranium etc atom form this types of hydrides.➡ follow me⤴⤴⤴⤴⤴⤴⤴⤴⤴⤴⤴⤴

draw isomers of METHANE and ETHANE BCOZ the consist of 1 and 2 CARBON atoms respectively and this 1 or 2 atoms cant be branched. HOPE IT HELPS!

tion. It can be prepared by treating BASIC beryllium carbonate with hot acetic acid. Basic beryllium acetate is insoluble in WATER but soluble in chloroform, CONSISTENT with it being NONPOLAR. It melts and sublimes in a vacuum without decomposition.Chemical formula: C; 12H; 18Be; 4O; 13Solubility in chloroform: solubleCAS Number: 19049-40-2EC Number: 242-785-4

is prepared by heating a mixture of propyl ALCOHOL and excess of CONCENTRATED sulphuric acid at 180°C. In first STEP, propyl hydrogen sulphate is formed which on heating .produces propene, which is collected over water.

ry and Physics are pretty much CONNECTED and essential to each other. SIMPLEST example would be the boiling and melting POINTS of a substance which are Physical quantities but is IMPORTANT in the study of chemistry.

o because it can DISSOLVE MANY solutes.Also KNOWN as UNIVERSAL SOLVENT.

electron is acepted by an ATOM energy is released and more the energy more is the electron AFFINITY. it is dependent on the effective nuclear charge of an atom. so it decreases down the group and increases along a period from LEFT to right.but there are some EXCEPTIONS as that of fluorine and chlorine , acc to the trend fluorne should have greater electron affinity but chlorine has the highest electron affinity as because of very small size of fluorine there are more electron pair repulsions and it makes fluorine less than chlorine in electron affinity. and the same can be SAID for oxygen and sulphur.

odide (also iodoethane) is a COLORLESS, flammable CHEMICAL compound. ... It may also be PREPARED by reaction between hydroiodic acid and ethanol distilling off the ethyl iodide.

are right. If you want explanation so, The molecules are continually colliding with each other and with the WALLS of the container. When a molecule collides with the wall, they exert small force on the wall The pressure EXERTED by the gas is DUE to the SUM of all these collision forces.The more particles that hit the walls, the higher the pressure.

he VALENCY is 3..the metal Is LIKELY to be ALUMINIUM..so Al + H2SO4 ------->Al2(SO4)3 + H2Al + NaOH -------> NAALO2 +H2KINDLY BALANCE!!

and KMNO4 GIVES ETHANOIC ACID

irical formula of this compound which CONTAINS 0.08 moles of CARBON and 0.32 moles of hydrogen is It MEANS this compound contains 0.08 moles of carbon and 0.32 moles of hydrogen is in the ratio of 1:4.So, this compound contains one part of carbon and FOUR part of hydrogen.Therefore, the name of the compound is

es above Copper in the reactivity series.Therefore, a CHEMICAL reaction has taken place between iron nails and Copper SULPHATE solution. We can also say that iron has displaced copper from Copper Sulphate solution.Since iron has taken part in the reaction, the colour of the solution becomes changes blue into green after a TEN MINUTES.

rium Carbonate decomposes its pH INCREASES.As we know that when pH increases hydronium ions DECREASES.So, when hydronium ion decreases it becomes ACIDIC in nature.Therefore, it is acidic in nature.We can check it by putting UNIVERSAL indicator in it, it turns RED in colour.Result:- It is acidic in nature.

MATE ❤️❤️❤️ HERE IS UR ANSWER.....HELIUM MOLECULE DOES NOT EXIST BECAUSE IT IS A NOBLE GAS WHICH EXITS IN ITS FREE STATE THAT IS ATOMIC STATE NOT IN A MOLECULE STATE....He HOPE THIS WILL HELP YOU ❤️ ❤️STAY BLESSED ❤️ ❤️❤️@PANKHUDI NEWELY JOINED ✌️✌️

ecause of the ring strain. Fortunately, the ORBITALS bend a LITTLE to compensate it, but that isn't enough to completely stabilize it.This MAKES it REACTIVE because it really wants to break those bonds and UNBEND the orbitals.

ng to FAZAN's rule,SMALLER the size of an atom HIGHER will be its polarising capacity.As we can see, in SnCl4 and SnCl2, the oxidation states of Sn are +4 and +2 respectively(this shows Sn in SnCl4 is smaller than Sn in SnCl2). That's the REASON behind the higher covalent nature of SnCl4.
