sence of water and OXYGEN is essential for the rusting of iron. Impurities in the iron, the presence of water vapour, acids, SALTS and carbon dioxide has since resting. PURE iron does not rust in and TRY and carbon dioxide free ad. It also does not rust in pure water, free from DISSOLVED salts.HOW THIS HELPS YOU.... ☺☺☺☺

ition of hydrogen is still not fixed in the periodic table some PROPERTIES of Hydrogen are same as that of alkalis well some are same as that of halogens hydrogen is a good reducing agent as that of alkalis and it also is ready to lose electrons to gain stability while in case of halogens hydrogen is ready to ACCEPT electrons to gain stability it is a non metal like them and Mand leave name did periodic table because in it the ELEMENTS are periodic functions the functions of these elements are REPEATED or after a fixed interval and these functions are placed in a tabular form therefore it is known as a table

hexafluoride. Sulfur hexafluoride (SF6) is a gas whose MOLECULES consist of one sulfur ATOM and six fluorine atoms. It is colorless, odorless, non-toxic, and non-flammable, and is SOLUBLE in water and some other LIQUIDS. Thi answer is HELPFUL

dy I think it's HELPFUL for you buddy The specific HEAT capacity of a substance is the amount of heat REQUIRED to raise one gram of the substance by one degree CELSIUS. Water, for example, has a specific heat capacity of 4.18 . This means to heat one gram of water by one degree Celsius, it would REQUIRE 4.18 joules of energy.

ev's periodic table suffered DEFECTS as follows: The position of hydrogen was not correctly defined. It was placed in group I although it resembles both the group I elements - the alkali metals and the group VII elements-the HALOGENS, in their properties. In some cases Mendeleev placed elements according to their similarities in properties and not in INCREASING order of their atomic masses. Thus, the position of these elements was not justified e.g. cobalt (atomic mass 58.9) was placed before nickel (atomic mass 58.6). Isotopes were not given separate places in the periodic table although Mendeleev's classification is based on the atomic masses. Some similar elements were grouped separately while some dissimilar elements were grouped together. For example copper and mercury are similar in their properties but were placed separately. Copper was placed in group I although it did not resemble the elements of this group. Mendeleev could not EXPLAIN the cause of periodicity in the elements. The position for lanthanides and actinides were not INCLUDED in this table.I hope it helpful to you.......

(1) Standard electrode potential: It is defined as the difference of clectrical potential between metal electrode and the solution around it EQUILIBRIUM when all the SUBSTANCES involved in the electrode reaction are in their standard states of unit activity or CONCENTRATION at constant temperature.(2) Standard OXIDATION potential : It is defined as the difference of clectrical potential betweea metal electrode and the solution around it at equilibrium due to oxidation reaction, when all the substances involved in the oxidation reaction are in their standard states of unit activity or concentration at constant temperature.(3) Standard reduction potential It is defined as the differenceof clectrical potential between metal electrode and the solution around it at equilibrium due to reduction reaction, when all the substances involved in the reduction reaction are in their standard states of unit activity or concentration at Constant temperature.

the CORRECT ANSWER

is extracted from the ore-argentite (\(Ag_2S\)). The process of extraction of SILVER is called as cyanide process as sodium cyanide solution is used. The ore is CRUSHED, concentrated and then TREATED with sodium cyanide solution. This reaction forms sodiumargento cyanide \(Na [AG(CN)_2]\)

The equivalent weight of glucoseBrainly.inWhat is your question?SECONDARY SchoolChemistry 50 pointsThe equivalent weight of glucose in C6H12O6 + 6O2 = 6CO2 + 6H20Ask for DETAILS Follow Report by Ashishpol0510ovaf1l 26.08.2017AnswersSiriChSiriCh AmbitiousFor this reaction, the mass of carbon dioxide and glucose involved are the PRODUCT of thier molar mass and the number of MOLES of each compound involved in the reaction. carbon dioxide: 6 x (12 + 2 x 16) = 264 glucose : 1 x (6 x 12 + 12 + 6 x 16) = 180Divide their masses to get the equivalent weights. The answer is 22/15 or 11/7.5.

carbon is a tetravalent element means that it has a large valence of 4 and it does not gain or loss electron (due to ENERGY consideration) to form a compound. So carbon only share electrons to combine with other ELEMENTS and form covalent bond. Carbon form a large no. of compound:– 1)because it has SELF linking property due to which it combine with itself and form a long CHAIN, this property is known as catenation.2)It is a tetravalent element.

ent bond is FORMED by two atoms sharing a pair of electrons. The atoms are HELD together because the ELECTRON pair is attracted by both of the nuclei.In the formation of a SIMPLE covalent bond, each atom SUPPLIES one electron to the bond - but that doesn't have to be the case. A co-ordinate bond (also called a dative covalent bond) is a covalent bond (a shared pair of electrons) in which both electrons come from the same atom.
