Air consists of many gases. HOWEVER the DENSITY of the different gases at different. As a result of this the most suitable method of separation of the components are fractional distillation.In this process there is distillation of different PARTS of air using their relative density or specific gravity. Hens gases with higher molecular weight is distilled in a different WAY as compared to gases with LOW molecular weight.

tion:Most compounds of transition METALS are paramagnetic, whereas virtually all compounds of the p-block elements are diamagnetic. The ELECTRONEGATIVITIES of the first-row transition metals INCREASE smoothly from Sc (χ = 1.4) to Cu (χ = 1.9). Thus Sc is a RATHER active metal, whereas Cu is much less REACTIVE.

b) HYDROCHLORIC acid Explanation:Gastric juice is MADE up of digestive enzymes, hydrochloric acid and other substances that are important for absorbing nutrients – about 3 to 4 liters of gastric juice are produced per day. The hydrochloric acid in the gastric juice BREAKS down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria. The MUCUS covers the stomach wall with a protective coating. Together with the bicarbonate, this ensures that the stomach wall itself is not damaged by the hydrochloric acid.

hyee..good morningyou answer is saltExplanation:When mixed, ACIDS and bases NEUTRALIZE ONE another and produce SALTS, substances with a salty taste and none of the CHARACTERISTIC properties of either acids or bases.hope this will help you...follow me ✌️✌️

ce of zinc is dropped in COPPER Sulphate solution ?→ So, here , on ADDING zinc to CuSO4 solution, zinc displaces copper from copper sulphate & forms zinc sulphate solution. This is indicated by colour change from blue to COLOURLESS. CuSO4 solution has a blue colour while ZnSO4 solution is colourless. → Zn(s) + CuSO4(aq) → Cu(s) + ZnSO4 (aq)

Number of electrons = Number of PROTONS, i.e ATOMIC number, so here the ELEMENT with atomic number 8 is OXYGEN.

We KNOW that number of ELECTRONS = number of protons, i.e Atomic number, so here element with atomic number 485 is EUROPIUM. HOPE it HELPS !!

7.38 g is the correct answer HOPE SO IT'S HELPFUL MARK AS BRAINLIST......FOLLOW ME....❤❤

Copper is an essential trace element that is included in some over-the-counter multivitamin and mineral supplements, even though copper deficiency is quite rare and supplementation is rarely needed. The amounts of copper found in TYPICAL supplements has not been associated with serum enzyme elevations or with clinically apparent liver INJURY. HOWEVER, accidental or intentional copper overdose can cause an acute liver injury and chronic ingestion of excessive amounts of copper can result in copper overload and chronic liver injury. LiverTox Cupric sulfate appears as a white or off-white solid. Melting point 200°C with decomposition. Non-combustible. CAMEO Chemicals Copper(II) sulfate is a metal sulfate COMPOUND having copper(2+) as the metal ION. It has a role as a sensitiser, a fertilizer and an emetic. It contains a copper(2+). Explanation:

A DEUTERON (proton-neutron pair) has a binding energy of 2.225 million ELECTRON volts (Mev) but an alpha PARTICLE has a binding energy of 28.3 Mev. (The higher the binding energy of a particle the more energy is REQUIRED to break it up into its constituent parts.)

According to BOYLE's Law, At constant n & T, the volume BEARS an inverse RELATION with the pressure exerted by a GAS. According to Charles' Law, ... When p & T are constant, then the volume of a gas bears a direct relation with the number of moles of gas.

Beryllium OXIDE (BeO) may form a CRYSTAL structure that consists of an HCP arrangement of O2− IONS. If the ionic radius of Be2+ is 0.035 nm, then.Explanation:

first case :-Initial velocity ( U ) = 0Final velocity ( v ) = 6 ms‐¹Time ( t ) = 30 ssubstituting the given values of u, v and t :-a = ( 6 ms‐¹ – 0 ms‐¹ ) / 30 sa = 0.2 ms‐²In the second case :- Initial velocity ( u ) = 6 ms‐¹ Final velocity ( v ) = 4 ms‐¹Time ( t ) = 5 sThen, a = ( 4 ms‐¹ – 6 ms‐¹ ) / 5 sa = – 0.4 ms‐²The acceleration of the bicycle in the first case is 0.2 ms‐² and in the second case it is –0.4 ms‐².

Atomicity is defined as the total number of atoms that constitute a molecule. For example, each molecule of oxygen (O2) is composed of two oxygen atoms.A precipitation reaction refers to the formation of an insoluble SALT when two SOLUTIONS containing soluble salts are combined. The insoluble salt that falls out of solution is KNOWN as the precipitate, hence the reaction's name. Precipitation reactions can help DETERMINE the PRESENCE of various ions in solution.

g of CUSO4 will PRODUCE = Answer AMOUNT of copper OBTAINED from 100 g CuSO4 = 39.8 g .Hope this will help you.Hope this will help you.All the best ✍️

Both sodium and magnesium are metals and thus, they are ELECTRON RICH in nature. ... Therefore in sodium chloride compound, electrons have been transferred from sodium ATOM to chlorine atom. As a RESULT, an ionic bond will be FORMED

it MAY be B is the CORRECT ANSWER

tion:You can calculate the ground state energy using The BOHR ModelExplanation:A simple expression for the energy of an electron in the HYDROGEN atom is: where the energy is in electron volts n is the principle quantum number.This gives rise to the familiar electron energy LEVEL diagram where they converge and coalesce.So for an electron in n=1E= -13.6e VTo convert to joules you can X this byFor many - electron atoms quite complicated approximate methods can be used which take into account factors such as electron interactions and screening effects.hope you have UNDERSTOOD...

Hydraulic Washing or Gravity SEPARATION MethodThis method is USED when the ORE particles are heavier than the IMPURITIES. The POWDERED ore is placed over a wooden inclined table. It is then sprayed with a stream of water which carries away the lighter impurities with it.

where: k is the rate constant, {H2} is the CONCENTRATION of hydrogen gas and {Cl2} is the concentration of chlorine gas; all are to the power one as MENTIONED in the balanced equation. So, the ORDER WOULD be: 1.

tion:PHOSPHINE is made industrially from white PHOSPHORUS by hydrolysis with an alkali metal hydroxide or an aqueous acid–catalyzed disproportionation reaction. The industrial product is NORMALLY SHIPPED as liquefied gas.
