s copper do not REACT with HCL?✨Copper is an INACTIVE metal✨Copper is LESS in reactivity series than Hydrogen.So does not displace Hydrogen.✨Hence is doesn't REACH with HCl.

the process of making sodium hydroxide from common salt is called electrolysisin this process a brime is decomposed ELECTRICALLY by passing CURRENT through it.brain is nothing but concentrated solution of sodium chloride in water.when current passes through this solution the ions breakdown into Na+ and OH-this any PLUS comes from the sodium chloride which breaks down electrolytically and the o h minus comes from the decomposed part of waterpH of a strong salt of a strong acid and strong base is 7 aur neutralwhere as PH made by a strong salt or a strong acid and weak base is less than 7 or ACIDIC

can be prepared by following steps:Take 100ml of water as SOLVENT and boil it few minutes. (ii) Now add one tea SPOON sugar, one tea spoon tea leaves and 50ml of milk. Here sugar, tea leaves and milk are solute. (III) Now boil it again for few minutes so that sugar will dissolves in solution as sugar is soluble in water (iv) Now filter the solution. Collect the filtrate in cup. The insoluble tea leaves will be left BEHIND as residue.

Copper is quite an unactive metal and does not react with dilute ACIDS under normal CIRCUMSTANCES. Copper is below HYDROGEN in the metal REACTIVITY series, so it does not displace Hydrogen under normal cases. ... Because the reduction potential of copper is POSITIVE, while the reduction potental for hydrogen is Zero.

are u solving AAKASH packageok...!in this QUESTION ...d =m/v1=m/1000mlm=1000gmoles=volume/22.4wt./M.Wt.=V/22.41000/18=V/22.455.56=V/22.4V=1244.4LI KNOW there is a slight difference in the ans.due to 55.55 and 55.56Explanation:Thankuu

Explanation:in the process of CHROMATOGRAPHY the COLOURED spot rises on the PAPER strip as it is SOLUBLE in water and thus due to their solubility the spot rises up .

Total no. Of LONE PAIR is 3 1 of NITROGEN ND 2 of oxygen

it is because ZINC is more REACTIVE than MERCURY but LESS reactive than MAGNESIUM

all STOICHIOMETRIC problems can be solved in just FOUR simple steps: Balance the equation. Convert units of a GIVEN substance to moles. USING the mole ratio, calculate the moles of substance yielded by the reaction. Convert moles of wanted substance to desired units.

M2O3.Explanation:From the question we know that the atomic WEIGHT of metal M is given as    56 gram. Again we get that the metal oxide contains 70% of the metal, so the remaining (100-70)=30% will be the oxide present in it.So, in 1 ATOM of metal if we TAKE N atoms of oxygen then the mass proportion of the metal and the oxygen will be :-56:n*16 = 70:30.16n=56*30/70.n=24/16 = 1.5. So, the whole NUMBER ratio will be 2:3.Therefore, we get that there will be two atoms of metal against the 3 atoms of Oxygen. So, the empirical formulae will be M2O3.

tion:the DENSITY of ice is less than that of water hence it will FLOAT on water.

this is the ANSWER of above question.mark as BRAINLIESTS answer....

tion:PCl₅ Molecule Hybridization: Sp³d hybridizationShape of molecule: Trigonal Bipyramidal geometryFive P-Cl sigma BONDS are formed.three of 5 P-Cl bomds lie in one plane at an angle of 120⁰ to one other called as Equatorial bonds.Other 2 P-Cl bonds are at RIGHT angle to the plane of equitorial bonds that is one above and one below the plane. These are called as AXIAL bonds.as one axial bond is at right angle to 3 equitorial bonds.then 3 axial bonds will at right angle to 6 equitorial bonds∴no. of right angle=6

4Explanation:there are FOUR RIGHT ANGLE

take a mixture of ethanol and acetone as an example. When ethanol is mixed with acetone, the hydrogen bonding between ethanol MOLECULES gets disturbed as actone molecules GET in between the ethanol molecules. This results in ΔmixH>0 as heat must be supplied to make the solution from its constituents(as attraction is less) but I am not SURE about ΔmixV. This page says it is greater than zero because VOLUME expands on mixing. But I think it should be less than zero because the observed vapour pressure is more than that predicted on the basis of theoretical calculations, so a greater AMOUNT of solution will be present in the form of vapour, hence volume of solution will be less (than the sum of the volumes of its constituents).hope helpful answer...follow me & mark brienlest answer...☺☺☺

Mark as me Brainliest SO I will follow you. The causes of the FRENCH Revolution can be attributed to several intertwining factors:Cultural: The Enlightenment philosophy desacralized the authority of the monarchy and the Catholic Church, and promoted a new society based on reason instead of traditions.Social: The emergence of an influential bourgeoisie which was formally part of the Third Estate (commoners) but had evolved into a caste with its own agenda and aspired to political equality with the clergy (First Estate) and the aristocracy (Second Estate).Financial: France's debt, aggravated by French INVOLVEMENT in the American Revolution, led Louis XVI to implement new taxations and to reduce privileges.Political: Louis XVI faced strong opposition from provincial parlements which were the spearheads of the privileged classes' resistance to royal reforms.Economic: The deregulation of the grain market, advocated by liberal economists, resulted in an increase in bread prices. In periods of BAD harvests, it would lead to food scarcity which would PROMPT the masses to revolt.[1][2][3]All these factors created a revolutionary atmosphere and a tricky situation for Louis XVI. In order to RESOLVE the crisis, the king summoned the Estates-General in May 1789 and, as it came to an impasse, the representatives of the Third Estates formed a National Assembly, against the wishes of the king, signaling the outbreak of the French Revolution.

ATE ANSWER ⏬⏺️To prepare 1M sulphuric acid from concentrated sulphuric acid:1)First consider the molecular weight of H2SO4 = 98 g/mol, so you have to add 98g of conc. acid and make up to 1 LITER of water (as pointed out at the 4thpoint).Considering that acid is a liquid, you should also consider density:where density = mass/VOLUME, which is said on the bottle to be (about) 1.84 g/mL,so then you have: volume = 98g / 1.84(g/mL) = 53.2 ML2)Now you have to consider the acid purity, usually 98% then you have to do this:53.2 mL if the acid were 100% pure CONVERT in mL given with the purity of 98%, so 100% x 53.2 mL / 98% = 54.3 mL of (98%) concentrated acid.3)Finally CAREFULLY add this 54.3 mL (or 98 g, cf. first POINT) to about 0.9 L dist. water while continuously stirring (evolving heat!), and after that fill it up to 1.00 L with also dist. water.Never reverse this: DO NOT add water to concentrated fluids!HOPE THIS HELPS YOU ☺️PLEASE FOLLOW ME ✌️MARK ME AS BRAINLIST

A group is a VERTICAL COLUMN of theperiodic table, BASED on the organization of the outer shell ELECTRONS. There are a TOTAL of 18groups.

The two TERMS-' residue' and 'filtrate' are used with RESPECT to the process of filtration. A given solution is allowed to undergo sedimentation after which it is filtrated. 'Filtrate' refers to the solution that passes through the filter whereas 'residue' refers to the substance that is LEFT behind after the filtration. These terms are also applicable in CASE of evaporation or distillation.
