Ans27.hybridisation REFERS to TALKING between two plants that are genetically dissimilar. Hybridization can be integergenetic, intraspecific or intervarietal.reasons for hybridization are producing a disease resistant variety that has a HIGH yield and low MATURITY duration

tance between (345) planes in a cubic lattice having length 7.7 A°​ is 1.089We know that, the distance can be REPRESENTED as :         1/ d² = h²/a² + k²/b² + l²/c²               EQ(1)As per the question, a = b = c =  7.7 A°​  and h = 3, k = 4, l = 5Now, PUTTING the values in eq (1), we GET,         1/d² = 3²/7.7² + 4²/7.7² + 5²/7.7²                = (3² + 4² + 5²) / 7.7²                = 50/59.29 X 10 ⁻²⁰                = 0.843 x 10²⁰Now, d² = 1/ 0.843 x 10²⁰                  d² = 1.186                   d = 1.089

C 2 H 5 −O−C 2 H 5 and CH 3 −CH 2 −CH 2 −O−CH 3 The IUPAC NAME of the two metamers are Ethoxy ethane and 1−methoxy propane.

27.hybridization is the process where genetically disimilar plants ,INTER species, intervariety plants are crossed this is to give the PLANT disirable AGRONOMIC characterExplanation:i am sorry I know only this ANSWER

Vitamins are SMALL but indispensable nutrients that or- ganisms cannot produce by themselves. Hormones serve as chemical messengers from one part of an organism to another. These too are the MOLECULES of life. ENZYMES are protein molecules that act as catalysts.

NH3N(12) H(3) 15u is the ANSWER of QUESTION of

avogadros lawExplanation:The the law state that equal VOLUME of all gases contents equal number of MOLECULES at constant temperature and pressure...it is CORRECT ANSWER please mark brainlist

2-methylbut-2-eneExplanation:you take the longest CARBON CHAIN which in this case is CH3-CH=C-CH3then you find out it there is a double or a Triple BOND between the carbon atoms which in this case is CH=Cthen you GIVE the smallest number to the double bond which in this case is "2" then see the what is add to the chain which in this case is a methyl on the SECOND carbon hence the name 2-methylbut-2-ene

option 4 (SIO3)n 4N TRIANGULAR units

the equilibrium SHIFTS in BACKWARD DIRECTION to undo the change in equilibrium effect........

A compound is a MOLECULE that contains at least two different elements. All compounds are molecules but not all molecules are compounds. Molecular HYDROGEN (H2), molecular oxygen (O2) and molecular NITROGEN (N2) are not compounds because each is COMPOSED of a single elementExplanation:

salt is the ANSWER...because it DISSOLVES fully in the water and FORMS solution not suspension.....hope it HELPS

e and diamond, both are ALLOTROPES of CARBON, so, they have the same chemical PROPERTIES. But, in graphite, each carbon atom shares ELECTRONS with 3 other carbon atoms, whereas in diamond, each carbon atom shares electrons with 4 other carbon atoms.

iii] in medicine and do detect underground pipe leakagesv]  Heating , electricity generation ,cooking, PRODUCTION of POLYMERS, making of drugs ,pesticides and other CHEMICALS and in paraffin wax. The usage can be differentiated according to the number of carbon atoms in the alkane.vi] C6H2Cl3OHvii] is a chemical bond that involves the sharing of electron pairs between atoms. usually betwwn TWO non metalsvii] changes in the TEMPERATURE, pressure, volume, or concentration of a system will result in predictable and opposing changes in the system in order to achieve a new equilibrium state.Explanation:

In Chemistry, the LAW of mass action is the proposition that the rate of the chemical reaction is DIRECTLY PROPORTIONAL to the PRODUCT of the activities or concentrations of the REACTANTS. It explains and predicts behaviors of solutions in dynamic equilibrium.

Potential ENERGY for water at 0 DEGREES is greater than potential energy for ice at 0 degrees. Explanation: You have to put in energy to convert ice to water at 0 degrees. Since energy is conserved, water MUST have HIGHER energy than ice.

hey mate please mark me as the brainliest PLZ plz plz plz plz plz plz plz plz Explanation:The necessary EQUIPMENT includes a mechanical shaker, 200-ML bottles, ... Add 0.05N hydrochloric acid until the mixture is just slightly acid, add 10 ml of ... to a 250-ml Erlenmeyer FLASK and add sufficient WATER to make the total volume 75 ml.

s a huge difference between REACTING and RESPONDING. A REACTION is typically quick, without much thought, tense and aggressive. A response is thought out, calm and non-threatening. A reaction typically provokes more reactions – perpetuating a long LINE of hatefulness with nothing accomplished.#MARK as Brainlist answer

Carbon oxygen is an INDICATIVE MEASURE of the AMOUNT of oxygen that can be consumed by reactions in a measured SOLUTION.

Ph scale was FIRST invented by Scientist Sorensen of Denmark It's a MIXTURE of pH papers that changes colour according to SOLUTION and indicates it's power of Hydrogen From that U can understand it's basicity or acidity Plz Follow kardo mujhe for many answers

The ANSWER is Be

tion:start by WRITING down the NUMBER of atoms in each ELEMENT, which is listed in the subscript next to each atom. Then, add coefficients to the atoms on each side of the EQUATION to BALANCE them with the same atoms on the other side.

Hey THEREBY ammonia process,SODIUM CARBONATE is not directly OBTAINED but instead FIRST the sodium bicarbonate is obtained then dehydration of it gives sodium bicarbonateHope it helps youPlease mark it as branliest

hey mate please mark me as the brainliest plz plz plz plz plz plz plz plz plz plz plz Explanation: As discussed in class the MO diagram for B2 SHOWS that it has two unpaired ELECTRONS (which makes it paramagnetic) and these electrons are in bonding MOLECULAR orbitals resulting in the equivalent bond strength of ONE bond. As discussed in class it is not a bond.
