lysis of aqueous SODIUM chloride: Electrolysis of aqueous NaCl results in hydrogen and chloride gas. ... At the cathode (C), water is REDUCED to hydroxide and hydrogen gas. The net PROCESS is the electrolysis of an aqueous solution of NaCl into INDUSTRIALLY useful products sodium hydroxide (NaOH) and chlorine gas.

A fluorine atom has 9 electrons while a fluorine ION (fluoride) has 10 electrons,  fluorine has an equal NUMBER of PROTONS and electrons 9, but a fluoride has one more ELECTRON than fluorine atom 9 and 10 respectively. Fluorine is electrically neutral, while fluoride is negatively charged.

acid or Base MIXES with water is called as the"Dilution ". and the SOLUTION is said to be " DILUTED".When an Acid or Base does not mixes with water is called as the " CONCENTRATION ". and the solution is said to be " Concentrated solution ".Concentration solution has more strength when Compared to the Dilution solution.I HOPE it will be helps you to understand about diluted and concentration.my answer is correct. if u think my answer is correct so please mark as brainliest.for better answers please follow me....................Please mark as brainliest...

In a nutshell, a chemical change produces a NEW SUBSTANCE, while a physical change does not. A material MAY change shapes or forms while undergoing a physical change, but no chemical REACTIONS occur and no new compounds are produced.

If we compare the IONIZATION energy between magnesium and aluminium, the magnesium has greater ionization energy as it has less no of shells which are closer to the nucleus. ... THEREFORE, the force of ATTRACTION between nucleus and the ELECTRONS decreases. Thus, it can remove electrons with less energy.Explanation:I HOPE IT'S HELP YOU IF IT'S HELPFUL PLEASE MARK ME AS BRANLIEST AND YOU CAN FOLLOW ME

Acid radical is the ION formed after the removal of Hydrogen ion (H+) from an acid. Example: When H2SO4 loses H+ ion, it forms HSO4− which is an acid radical. The ion formed after the removal of hydroxide ion (OH−) from a base is known as basic radical.Explanation:I HOPE IT'S HELP YOU IF IT'S HELPFUL PLEASE MARK ME AS BRANLIEST AND YOU CAN FOLLOW ME

te..........Sodium is USED as a HEAT exchanger in some nuclear reactors, and as a reagent in the chemicals industry. But sodium salts have more uses than the metal itself. The most common compound of sodium is sodium chloride (common salt). It is ADDED to FOOD and used to de-ice ROADS in winter.Hope this will help you....... #AD

Cavities are permanently damaged areas in the hard surface of your teeth that develop into tiny openings or HOLES. Cavities, also called tooth decay or caries, are caused by a COMBINATION of factors, including bacteria in your MOUTH, frequent snacking, SIPPING sugary DRINKS and not cleaning your teeth well.Explanation:hope it help you..

he best reagent to convert methanol (CH3OH) to CH3Cl is SOCl2 . The reaction goes like this :-CH3OH + SOCl2 ---> CH3Cl + SO2 + HCl.This is the best method because the other two product SO2 and HCl are gases.ADDITIONAL DETAILS FOR IIT-JEE .This reaction is an SN-2 reaction.If the reactant has a chiral carbon, two TYPES of reactions occurs.In the PRESENCE of pyridine :- We get inverted product.In the absence of pyridine :- We get a product with retention in configuration. This reaction follows a mechanism called SN-i (internal)

The platinum or carbon electrodes are inert. You need inert (non–reactive) electrodes like platinum (LEFT) and MUCH CHEAPER carbon (GRAPHITE electrodes, right). In the simple electrolysis cell, the graphite (carbon) electrodes are, through a large rubber BUNG, 'upwardly' dipped into an solution of acidified water.PLEASE FOLLOW ME

tion:For INSTANCE if you have a sample of liquid water, it has a MASS DENSITY of 1 g mL-1. Since water has a MOLECULAR weigh of 18 g mol-1, 1 mole will have a mass of 18 g. From the density this should have a volume of only 18 mL.

Å = and, 1 NM = Hence, 10 Å = 1 nm => 1 Å = 1/10 nm=> 13.225 Å = 1.3225 nm Answer

Butan-1-olExplanation:The one in the question CONSISTS of 3 carbon atoms and a HYDROXY group at the first position, that is propan-1-ol. So the next HOMOLOGUE will consists of one more carbon atom, hence the ANSWER.

tion:There is also evidence that in METAL carbonyl hydrides LIKE these, the HYDROGEN bears a partial negative charge, although this argument is not without its caveats. Therefore, the oxidation STATE of Mn should be +1

tion:They are typically heat-resistant and either liquid or rubber-like, and are used in sealants, ADHESIVES, lubricants, medicine, cooking utensils, and thermal and ELECTRICAL insulation.

Hybridization happens when ATOMIC orbitals mix to FORM a NEW atomic ORBITAL. The new orbital can hold the same total number of electrons as the old ones. The properties and energy of the new, hybridized orbital are an 'average' of the original unhybridized orbitals.Explanation:MARK ME AS BRAINLIST..FOLLOW ME✊.
