ANSWER:

The REACTION which releases HEAT during reaction is CALLED exothermic reaction.

Answer:

Doctor advises to keep a strip of wet CLOTH N the forehead of a PERSON having fever because due to high fever ,a person FEELS ill . The strip of wet cloth is COLDER than the body temperature.

When we keep the strip of wet cloth, the heat of the forehead gets transferred to the wet cloth and the coldness of the cloth gets transferred to the forehead and so the person suffering from fever feel well as some amount of heat gets transferred to the cloth and the temperature lowers .

EXPLANATION:

oth a SOLUTE and a solvent are components of a solution which is a homogenous mixture. Many solutions in chemistry are aqueous solutions.

oth a solute and a solvent are components of a solution which is a homogenous mixture. Many solutions in chemistry are aqueous solutions. Since the solution is a physical mixture, separation involves using a physical process such as evaporation or distillation.The water can be evaporated leaving the dry solute behind and then the water can be CONDENSED.

Chromatography can also be used to separate different solvents such as in high performance liquid chromatography. In a chromatography, different SOLUTES adhere to medium due to intermolecular bonding. For examples in protein purification, a column of resin beads can be used to separate different protein solutes based on HYDROPHOBIC or hydrophilic properties.

Explanation:

Enthalpy of atomisation: Enthalpy of atomisation is the CHANGE in enthalpy when one MOLE of bonds are completely BROKEN to obtain atoms in the gas PHASE. Transition elements have HIGH effective nuclear charge and a large number of valence electrons. Therefore, they form very strong metallic bonds.

Explanation:

CESIUM. Sulphur and CHLORINE will gain electrons 100% of the TIME in ionic bonding scenarios. BERILLIUM is higher

EXPLANATION:

Non-ionising radiation does not penetrate deep into the tissues but increases the RISK of damage to the SKIN and eyes. Dependent on the energy and exposure time, non-ionising radiation can cause localised heating, or photochemical reactions can occur with possible PERMANENT harm. Exposure should THEREFORE be minimised

Explanation:

F-centers...

An F-center, FARBE center or color center (from the original German Farbzentrum, where Farbe means color and zentrum means center) is a TYPE of crystallographic defect in which an ANIONIC vacancy in a crystal lattice is OCCUPIED by one or more unpaired electrons.

Unit cell

the smallest group of atoms which has the OVERALL symmetry of a crystal, and from which the entire lattice can be built up by repetition in three dimensions.

it reacts with it and PRODUCES CO2 carbon dioxide

Hi there,

♡ Welcome to brainly FAMILY

◇ Given

☆ C atomic MASS = 12

☆ O atomic mass = 16

☆ N atomic mass = 14

☆ H atomic mass = 1

♤ Molar mass is the sum of atomic masses of each element in the COMPOUND

◇ CO(NH2)2

◇ C + O + 2N + 4H

◇ 12 + 16 + 14×2 + 4×1 = 60 g/mol

♡ Hope the answer is helpful

♡ Plz mark it as brailiest

MOLES = GIVEN mass/molar mass = 320/32 = 10 moles.

Now,

1 mole corresponds to Avogadro's number.

So, 10 moles corresponds to 10 times the Avogadro's number

= 6.022×10²⁴ MOLECULES.

ANSWER:

this method is used to seprate 2 or more missible LIQUID or gases whose boiling point has a differebt of less than 25 celvin.

1) it is carryout in a fractional column which consists of glass TUBE with glass beats in it.

2) glass beats provide surface for the vapour to cooland condeness RAPIDLY.

what is this I don't KNOW

v= 0.02* (z/n) amstong

Because chemical changes produce new substances, they OFTEN cannot be undone. For EXAMPLE, you can't change ashes from burning logs BACK into WOOD. Some chemical changes can be reversed, but only by other chemical changes.

ANSWER:

the above ROUGH FIG. SHOWS ray diagram.

EXPLANATION:

Depression of freezing point by impurities. The presence of impurities LOWERS (depresses) the freezing point of a liquid. The impurities lower the vapour PRESSURE of the solution so that ICE can melt at a lower TEMPERATURE.

2 NA ( s ) + CL 2 ( g ) → 2 NACL ( s ) 2.

ANSWER:

when ZN is ADDED to cuso4 then zn dispaces cu from the solution and the COLOR of solution changes from blue to colorless.

Equation-

zn+cuso4=znso4+cu

EXPLANATION:

There will be no REACTION. This is because a metal with a low electropositive character will not REACT with the salt

Explanation:

What happens when zinc granules are treated with dilute SOLUTION of H2SO4, HCL, HNO3, NaCl and NaOH, ALSO write the chemical equations if reaction occurs. ... Since, zinc is less reactive than sodium, THUS no reaction takes PLACE when zinc granules are treated with sodium chloride

When iron rod is kept dipped in copper sulphate solution for sometimes a BROWN coating is formed on the solution on the iron rod. this happens, ACCORDING to reactivity SERIES we know that iron is more reactive than copper so iron DISPLACES copper from copper sulphate and FORMS iron sulphate.

When COPPER vessel is exposed to MOIST air for long time , the metal reacts with GASSES and moisture and ATMOSPHERIC gasses to form a mixture of copper carbonate and copper hydroxide. This gives green COLOUR to the surface of the copper metal.

EXPLANATION:

On dropping a few drops of HCL in a test tube containing distilled water it BECOMES dilute and its PH changes. ... On dropping a few drops of HCL in a test tube containing Sodium CARBONATE, a brisk effervescence of carbon DIOXIDE is formed with salt formation

Answer:

bonjour

Explanation:

In actual FACT, the term "shock absorber", which is customary in the trade, is misleading. Shock absorbers do not absorb shock. Their job is to REDUCE and decelerate the vibrations of vehicle springs. Together, the springs and the shock absorbers provide the link between wheel suspension and car body, working as a TEAM to compensate uneven road surfaces. The frequency of vibrations emanating from the wheel is approximately TEN times higher than the vibrations of the car body – sprung mass, to use the technical term. The shock absorber is the means via which these vibrations are dampened. In technical TERMS, this component is not a shock absorber then, but a vibration absorber.

Answer:

In METALLIC bonds the valence electrons from the S and P orbitals of the interacting metal atoms delocalize. That is to say instead of ORBITING their respective metal atoms, they form a "sea" of electron that surrounds the positively changed ATOMIC nuclei of the interacting metal IONS.
