re 3 electrons in this ion, hence, 3 moles of electrons are present in 1g-ion or 1 mole of N3−. The charge present on 1 mole of electrons has ALREADY been DEFINED by FARADAY, it is known as the Faraday's CONSTANT and it is denoted by F.

redox REACTION is your ANSWER mark me BRAINLIEST plz

If anyone AGREES with me then REPLY and write yes in my COMMENT

Avogadro's LAW states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a GIVEN MASS of an ideal gas, the volume and AMOUNT (MOLES) of the gas are directly proportional if the temperature and pressure are constant.Hey Mate!!!! Here is your answer ♣️

Air is a MIXTURE but not COMPOUND. Its CONSTITUENTS can be separated. For example: OXYGEN, nitrogen ETC.

When the battery is FULLY charged, its positive plate is of NI(OH)4 and its NEGATIVE plate is of IRON (Fe). The electrolyte used is potassium hydroxide (KOH).

tion:What happens to the volume of a fixed MASS of gas when its pressure and temperature (in Kelvin) are both doubled? It will not change. ... The temperature in Kelvin of a 2.0 dm^3 of an IDEAL gas is doubled and its pressure is increased by a factor of 4.mark as BRAINLEST ANSWERED

Molar mass of ethene C 2 H 4 =2(12)+4(1)=28 g/mol7.0 g ethene corresponds to 28g/mol7.0g =0.25 moles 1 mole of ethene GIVES 2 moles of CO 2 .0.25 moles of ethene will GIVE 0.50 moles of CO 2 .Molar mass of CO 2 is 44 g/mol.Mass of CO 2 will be 44 g/mol × 0.50 mol= 22 gHence, option B is correct.

tion:The molarity of the solution is 4.22M. THEREFORE 4.22 mol of H 2 SO 4 is present in 1000cm 3 of solution.Now M(molar mass of H 2 SO 4 )=98g(mol) −1 W(mass of H 2 SO 4 )=4.22×98=413.56gmass of the solution=density×volume=1.21×1000=1210gmass of water(solvent)=1210g−413.56g=796.44g=0.79644kgm(molality)= mass of solvent(in kg)N solute m= 0.79644kg4.22mol =5.298mol(kg) −1

, two years after he created his FAMOUS periodic table, RUSSIAN chemist Dmitri IVANOVITCH Mendeleev (1834-1907) predicted the existence of an element he called "eka-SILICON." This turned out to be germanium, which sits directly beneath silicon on the periodic table, and which was DISCOVERED in 1886 by German. Mark Me As Brainslist✔

energy is the QUANTITATIVE property that must be transferred to a body or PHYSICAL system to perform work on the body, or to heat it. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in FORM, but not CREATED or destroyed.

Anti-bonding orbitals are formed where the atomic orbitals combine such that it leads to predominantly DESTRUCTIVE interference i.e. subtraction of WAVE function. The most important feature of antibonding orbitals is that the molecular orbitals have higher energy than the corresponding atomic orbitals.Hey MATE!!!! Here is your ANSWER ♣️

ss steel is generally provided with a COPPER bottom because copper is a very good CONDUCTOR of heat and electricity. Thus, it helps in directing the heat evenly throughout the utensils, and heats the steel pans FASTER. So cooking process will TAKE less time.

on. Ionic bonding can result from a redox reaction when atoms of an element (usually metal), whose IONIZATION ENERGY is LOW, give some of their ELECTRONS to achieve a stable electron configuration. ... These ions are then ATTRACTED to each other in a 1:1 ratio to form sodium chloride (NaCl).

n:Given COMPOUND : ( Aluminum oxide )We've to find its percentage composition.Let's find the molecular MASS of ALUMINIUM oxide Firstly.→ Molecular mass of Aluminium oxide = 27 ( 2 ) + 16 ( 3 )→ Molecular mass of aluminium oxide = 54 + 48→ Molecular mass of aluminium oxide = 102 gNow, we have to find the percentage composition of oxygen in aluminium oxide.→ → 47.05 %Hence, percentage composition of oxygen in aluminium oxide is 47.05%
