d is CORRECT ANSWER.......I HOPE you...........

: The order of acidic nature would be: water > ETHYNE > ammonia > ethane.Since oxygen has highest electronegativity amongst the atoms of the compounds, so its hydrogen will be most acidic and hence will be best acid among them.Ethyne contains sp-carbon and as a result the electronegativity of the carbon in ethyne is more than sp3 due to increased s-character (50%) in the bonds between the carbon atoms.The electronegativity of the carbon increases to a great EXTENT when and turns out to be 3.2, which is GREATER than the electronegativity of nitrogen which is 3.04. Hence the hydrogen of ethyne is more acidic than that of NH3.Ethane does not POSSESS any acidic hydrogen hence it is least acidic.

Does ammonia evolve from a solution of NH4CL?Dear all,As per the literature NH4Cl when dissolved in water, its pH needs to be increased beyond 8.5 and preferably 10.5 (by addition of CaO) so that NH4+ is CONVERTED to NH3 and evolution occurs.My questions to you all is if I dissolve NH4Cl in water (to say 1000 ppm CONCENTRATION) and heat this solution to 70-80 C, does heating also promote some LOSSES of NH3?........Explanation:HOPE IT HELPS...PLEASE MARK IT AS THE BRAINLIEST!!

A Diagonal Relationshipis said to exist between certain PAIRS ofdiagonally adjacent elements in the SECOND and third periods of the periodic table. These pairs (Li & MG, Be & Al, B & Si ETC.) ... Such a relationship OCCURS because crossing and descending the periodic table have opposing effects.Explanation:please make it brainly

It is MADE up of the anther that holds the pollen and a stalk called the filament on which the anther sits. In a hibiscus flower, the filaments fuse into a TUBE that surrounds the style. Numerous anthers stick out from the filaments ALMOST LIKE the FEATHERS on a feather duster.

_______❤The rate at which a radioactive isotope DECAYS is measured in half-life. The term half-life is defined as the time it takes for one-half of the atoms of a radioactive MATERIAL to DISINTEGRATE. Half-lives for various radioisotopes can RANGE from a few microseconds to billions of years.❤______________

Despite continuous ADVANCES in the medical world, obesity continues to remain a major worldwide health HAZARD with adult mortality as high as 2.8 million per year. The majority of chronic diseases like diabetes, hypertension, and heart DISEASE are largely related to obesity which is usually a product of unhealthy lifestyle and poor dietary habits. Appropriately tailored diet regimens for weight reduction can help manage the obesity EPIDEMIC to some EXTENT. One diet regimen that has proven to be very effective for rapid weight loss is a very-low-carbohydrate and high-fat ketogenic dietExplanation:Despite continuous advances in the medical world, obesity continues to remain a major worldwide health hazard with adult mortality as high as 2.8 million per year.

.....Explanation:Like pricing on the financial MARKET, the most basic principles of supply and demand are responsible for price fluctuations in the energy market. The price for electricity or natural gas will vary DEPENDING on how MUCH BUYERS need and how much the market has to offer.....THANKS.......

Explanation:Sodium carbonate is a compound (X) which is used in glass and soap industry.Its chemical formula is Na2CO3.Ammonia and carbon DIOXIDE gas is PASSED through brine solution (or sodium chloride solution). As a result, a mixture of NaHCO3 and NH4Cl formed.On heating NaHCO3, sodium carbonate, WATER and carbon dioxide are formed.Anhydrous sodium carbonate is dissolved in water. The solution is concentrated and upon cooling, it GIVES hydrated sodium carbonate (called WASHING soda).

tion:Dihydrogen fuel is a zero-emission fuel when BURNED with oxygen (if ONE CONSIDERS water not as an emission) or used in a contained cell. The energy released enables hydrogen to ACT as a fuel. In an ELECTROCHEMICAL cell, that energy can be used with relatively high efficiency.

tion:Formula in HILL system is C2KNaO4. Computing molar mass (molar WEIGHT). To calculate molar mass of a CHEMICAL COMPOUND enter its

tion:bhai.... oxidation Hai tune ye Kaha se doonda options wrong HaiBecause, the OXIDATIVE rancidity is ASSOCIATED with the degradation by oxygen in the air. The double bonds of an unsaturated fatty acid can be cleaved by free-radical reactions involving MOLECULAR oxygen. HENCE, Oxidative Rancidity is AN OXIDATION reaction.

tion:That is because the lithium ATOM always has 3 PROTONS, the atomic number for lithium is always 3. The mass number, however, is 6 in the isotope with 3 NEUTRONS, and 7 in the isotope with 4 neutrons.ISOTOPES are elements with same atomic number but Isotopes are elements with same atomic number but DIFFERENT atomic mass number

tion:a subatomic particle of about the same MASS as a proton but without an electric CHARGE, present in all atomic NUCLEI EXCEPT those of ordinary HYDROGEN

tion:The C-terminal residue is determined by the use of EITHER a chemical REAGENT or the enzyme carboxypeptidase. The chemical reagent hydrazine forms aminoacyl hydrazides with every residue except the C terminus (Figure 3-10). The C terminus is thus readily identified by CHROMATOGRAPHIC PROCEDURES. The disadvantage of hydrazinolysis is that the entire sample is used to DETERMINE just one residue.
