ple of a simpler chemical change is the burning of methane. Methane is the main component of natural gas, which is burned in many home furnaces. During burning, methane combines with OXYGEN in the AIR to produce entirely different chemical SUBSTANCES, including the GASES carbon dioxide and WATER vapor.

Which of the FOLLOWING gives ESTER TEST?b. (i) and (IV)

gas shift reaction is DEFINED as the reaction between carbon monoxide and WATER vapor to form carbon DIOXIDE and HYDROGEN. The MIXTURE of carbon dioxide and hydrogen is known as water gas. This reaction is more catalyzed on iron catalysts and merely catalyzed by cobalt catalysts.

Covalent crystals TEND to be HARD and to have very high melting points because of the strong attractions between covalently BONDED atoms. They do not conduct electricity because the electrons are bound too TIGHTLY to the bonds.Mark me as brilliant

Physical Properties of DIHYDROGEN -It is colourless, tasteless, ODOURLESS gas.It has extremely low solubility in water. Since its molecules are non-polar.Its DENSITY is approximately 1/4th that of air. So lightest SUBSTANCE knownIt can be liquefied at high pressures and very low temperature.It is highly combustible and should be handled with care. ✧ParadiseLost✧

Covalent crystals tend to be hard and to have very high MELTING points because of the strong attractions between covalently BONDED atoms. They do not CONDUCT ELECTRICITY because the electrons are bound too TIGHTLY to the bonds.

re 3 physical states of MATTER and they are-* SOLID* LIQUID* GAS

n has three naturally OCCURRING isotopes: 1H (protium), 2H (deuterium), and 3H (tritium). Other highly unstable nuclei (4H to 7H) have been synthesized in the laboratory, but do not occur in nature. The most stable radioisotope of hydrogen is tritium, with a half-life of 12.32 YEARS. All heavier isotopes are synthetic and have a half-life less than a zeptosecond (10-21 SEC). Of these, 5H is the most stable, and the LEAST stable isotope is 7H .

the HYDROGEN is on the FIRST place because it Electronic configuration is 1.It MEANS only 1 electron is present. please mark it as BRAINLIEST and also click on a small heart and follow me

the QUESTION MATE?

1 *Chromatography *it is the process in which we can SEPARATE The mixture or SOLUTION into ISOLATED one2 *5-10 MINS.

The REACTION is DISPLACEMENT

☺UR ANSWER IS HEREAn organic acid is an organic COMPOUND with acidic properties. ... Sulfonic acids, containing the group –SO2OH, are relatively stronger acids. Alcohols, with –OH, can act as acids but they are usually very weak. The RELATIVE stability of the conjugate BASE of the acid determines its acidity.HOPE IT HELP U☺☺✌✌PLZZ MAKE ME AS BRAINLEST PLZZ☺☺✌✌❤✔

tion:An inductive effect is the effect on electron density in ONE portion of a MOLECULE caused by electron-withdrawing or electron-donating groups elsewhere in the molecule. ... The electromeric effect is an INTRAMOLECULAR MOVEMENT of electrons from a pi bond to ANOTHER atom in the molecule due to attack by a reagent.

decomposition of Ca(OH)2 under atmospheric water vapor exhibits special features, including an induction PERIOD (IP) and a subsequent sigmoidal mass-loss behavior under isothermal CONDITIONS. Atmospheric water vapor reduces the reaction rate at a specific temperature and causes a systematic shift of the mass-loss curve, which was recorded at a specific heating rate, to higher temperatures as the water vapor pressure, p(H2O), increases. The CHALLENGE in this study was to universally describe the kinetics of thermal decomposition under various p(H2O) conditions by introducing an accommodation function in the fundamental kinetic equation. The accommodation function in the multiplied form of two p(H2O) components with a variable exponent in each component was derived on the basis of the classical NUCLEATION and interface reaction theories. The universal kinetic approach was realized by applying the accommodation function to formal kinetic analyses of the Arrhenius plot for the IP and the Friedman plot for the mass-loss process. Furthermore, the overall reaction process under isothermal conditions was analyzed kinetically on the basis of the physico-geometrical consecutive reaction model, which was composed of an IP, a surface reaction (SR), and a phase boundary-controlled reaction (PBR). Subsequently, the kinetic parameters for each physico-geometrical reaction step were determined by the modified Arrhenius plot with the accommodation function. The impact of the atmospheric water vapor on the kinetics of thermal decomposition was characterized in CONNECTION with physico-geometrical reaction mechanisms through the interpretation of the kinetic parameters and these variation behavior patterns as the overall reaction advanced.

hey mate here is UR answer 10 i.e NEON,

Thermoplastics and thermosetting plastics are TWO SEPARATE classes of polymers, which are differentiated based on their BEHAVIOR in the presence of heat. The material DIFFERENCE between the two is that thermoplastics can be remelted, while thermoset plastics remain in a PERMANENT solid state once hardened.Explanation:

hanks for the question....!The CORRECT answer is 3) both the above. also a CARBANION. Since, it has negative charge,it is a nucleophile.Also, since the electron pair is available for donation ,it is a BASE also

y of MATTER PRESENT in an OBJECT is CALLED MASS

- COLLIGATIVE PROPERTY CONCEPT :- NaCl molecule dissociates in AQUEOUS solution. in such case ( Van't hoff's factor)i = So, in case of NaCl i = 1/2 ( as it dissociates into Na+ and Cl-)Now, i also EQUALS = Since, i = 1/2Thus, normal molar mass × 2 = calculated molar mass.Hence, molar mass of NaCl is half the calculated molar mass.

here the ANSWER....B is the CORRECT OPTION and..that is METHYLAMINE

aExplanation:option a is not BALANCED. there is NOTHING in PRODUCT side
