i) METAL X is Copper, as Copper oxide when reacts with Hydrogen GIVES Copper and Water. II) Gas Y2 is Hydrogen , since it reacts with Copper oxide to give Copper and Water. III) Compound XO is Copper oxide (CuO) since it reacts with Hydrogen and gives Copper and Water. iv) Compound Y2O is Water (H2O), as Copper oxide when reacts with Hydrogen gives Water and Copper. v) The chemical reaction which takes place on heating XO with Y2 is - CuO+H2 -> Cu+H2O. vi) This kind of reaction is CALLED displacement reaction as copper is being displaced by hydrogen from its oxide to form water.

tion:(a) Metal X is COPPER (Cu) (b) The SALT YNO3 is Silver Nitrate. (AgNO3)(C) Metal Y is silver (Ag)(d) The salt X(NO3)2 is Copper Nitrate. (e) Displacement reaction takes place between metal X and salt solution YNO3.The reaction is - Cu + AgNO3​ → Cu(NO3)2 + Ag

re the ANSWERS for your QUESTIONS

Hey mate here is your ANSWER ⤵⤵If two compounds have same EMPIRICAL formula they must have :- a.) DIFFERENT %age of composition. B.) ✔✔different molar mass✔✔c.) same viscosityd.)same vapour densityI hope it helps u.....# Follow me ❤❤

, for example, is a metalloid that has the visual appearance of a metal, but is a poor conductor of ELECTRICITY; METALLOIDS are generally semiconductors. The elements CLASSIFIED as metalloids are BORON, silicon, germanium, arsenic, antimony, TELLURIUM, and polonium.

Hey...EXPLANATION:The language in organic chemistry does not permit the DESCRIPTION exect...it is the easiest way that CHEMIST can DESCRIBE different ... structure MUST have the same number of paired and unpaired electrons I HOPE IT WILL HELP YOU Bye...

tion:ACYLATION is the process of ADDING acyl GROUP to any COMPOUND.

Hey mate here is your answer ⤵⤵N2 + 3H2 -> 2NH32(14) + 6 -> 2 (17)28 + 6 -> 34Now, 1.5 = 34 ÷ 28 = 34 × 1.5 ________________ 28 = 35.5 _______ 17 = 2.088I hopeit HELPS u ........#Follow me ❤❤

Option B => 85.7 gExplanation:MOLAR mass of AG2S : =>  108 x 2 + 32  = 248 g/molMass of silver in 1 mole of Ag2S : => 108 x 2 = 216g216 g of AG is contained in 248g of Ag2S1 g of Ag is consists in =  => 1.148 g of Ag2SThe ore consists 1.34% Ag2S∴ 1.34% ≡ 1.148 g100% : 100% ≡ => 85.7 g.

tion:D) BeF2 can FORM COMPLEX of the TYPE (NH.), BeF, but other alkaline earth metalfluorides cannot form such complexes.

Vapour pressure is a measure of the tendency of a material to change into the GASEOUS or vapour state, and it increases with temperature. The temperature at which the vapour pressure at the surface of a liquid becomes EQUAL to the pressure exerted by the SURROUNDINGS is CALLED the boiling point of the liquid.

xamples of ALLOY :◆Steel, a combination of IRON (metal) and CARBON (non-metal)◆Bronze, a combination of copper (metal) and tin (metal) and.◆Brass, a mixture of copper (metal) and zinc (metal)EXAMPLES of Metals :◆ Gallium◆ Copper◆ Iron◆AluminiumGlad to help yaa!!❤️

An element is a substance whose ATOMS all have the same number of PROTONS: another way of saying this is that all of a PARTICULAR element's atoms have the same atomic number.Elements are chemically the SIMPLEST substances and hence cannot be broken down using chemical reactions. Elements can only be CHANGED into other elements using nuclear methods.Explanation:An Element is a pure substance which is made up of same kinds of Atoms

Metal REACT with WATER to FORM metal HYDROXIDE or metal oxide and HYDROGEN gas.

a2SO3 + H2O---) SO2 + 2NaOHHope it HELPS ☺️

Answer:Metals FORM respective metal HYDROXIDE and HYDROGEN gas when REACT with water.

Explanation:ideal gas EXISTS in all TEMPERATURES and pressures but an real gas EXIST only at low temperatures and HIGH pressures
