Repeating an EXPERIMENT more than once helps determine if the data was a fluke, or REPRESENTS the normal case. It helps guard against jumping to conclusions without enough evidence. The number of repeats depends on many FACTORS, including the SPREAD of the data and the AVAILABILITY of resources.

METAL+WATER=METAL OXIDE+HYDROGEN and METAL+ACID=SALT+HYDROGEN are not similar as one they form different products and water does not react LIKE acid.  EXPLANATION:For e.g-: Na + O2 gives Na2O + H2 where as Na + HCL gives NACL + H2

If RATE LAW for a reaction is expressed as r=k[A]  p [B]  q  then  order of reaction with respect to A is 'p' order of reaction with respect to B is 'q' overall order of the reaction is 'p+q'. Hence, for the Rate Law : r=k[CL  2 ​   ][NO]  2  order of reaction with respect TOCL  2 ​    is   ′ 1  ′  order of reaction with respect to NO is   ′ 2  ′  overall order of the reaction is   ′ 3  ′ .Explanation:

ctural isomerism:- Compounds having same molecular formula but different molecular structures.eg:-Butane and Isobutane(C H ) 4 10 b) Covalent bond:-It is a chemical bond in which pairs of electrons are shared between two atoms.eg:-water and diamondc) Hetro atom in a CARBON compound:- It is a compound formed by replacement of carbon and hydrogen by HETEROATOM in a compound.eg:-oxygend) Functional group:- an atom or a group of atoms present in a molecules,which determine the characteristics property of the organic compounds is called functional group.eg:-alcohol(OH)e) AlkaneIt is a organic compounds that consists single BOUNDED carbon and hydrogen atoms.eg:-methane and heptanef) Unsaturated hydrocarbon:-It is a hydrocarbons that have double or triple covalent bonds between adjacent carbon atoms.eg:-alkaneg) homopolymer:-a polymer consists of identical monomer units.eg:-PVC with vinyl chloride.h) Monomer:-It is a simple molecule with two or more binding sites.eg:-glucose,amino acidI) Reduction:-It is a gain of electrons.eg:-iron reacts with oxygenj) Oxydant:-It is a loss of electrons.eg:-METAL reacts with oxygenI HOPE THIS ONE HELPS YOU(◍•ᴗ•◍)

(C) is the ANSWER. Lautomer.

The definitions of electrical units that were proposed at the 1881 International Conference of Electricians were DESIGNED so that the electromotive force of the Daniell cell would be about 1.0 volts. With contemporary definitions, the STANDARD potential of the Daniell cell at 25 °C is ACTUALLY 1.10 V.Explanation:hope it helps...mark as BRAINLIEST

I cant GIVE ANSWER of this question BCZ this question is too LONG

tral atom phosphorus is sp3 hybridized. ... Higher the ELECTRON DENSITY of phosphorus more will be the lone pair-bond pair repulsion. The GREATER the repulsion the more is the bond angle. THUS the bond angle of PF3 is lowest and the bond angle of PI3 is highest.Hope it helps:)

Reactive dyes are by FAR the best choice for dyeing cotton and other cellulose FIBERS at home or in the ART studio. DISPERSE dyes were originally DEVELOPED for the dyeing of cellulose acetate, and are water-insoluble.Explanation:

ivalent conductance of an electrolyte is defined as the conductance of a volume of solution containing one equivalent weight of DISSOLVED substance when placed between TWO parallel electrodes 1 CM apart, and LARGE ENOUGH to contain between them all of the solution.

I AM SURE THAT IS CORRECT ANSWER AND PLEASE MARK ME BRAINLIST ANSWER

Example: HYDROCHLORIC acid, nitric acid, acetic acid. Dibasic acid- Dibasic acids are acids that furnish TWO hydrogen ions (H+) per molecule in WATER.

The metal OXIDE which cannot be reduced by hydrogen is (SODIUM oxide, COPPER oxide).MARK MY ANSWER AS BRAINLIST

PH, quantitative measure of the acidity or basicity of aqueous or other liquid solutions. The term, WIDELY used in chemistry, BIOLOGY, and agronomy, translates the values of the concentration of the hydrogen ion—which ordinarily ranges between about 1 and 10−14 gram-equivalents per litre—into NUMBERS between 0 and 14

Adaptation can either occur in ANTICIPATION of change (anticipatory adaptation), or be a response to those CHANGES (reactive adaptation). Most adaptation being implemented at PRESENT is responding to CURRENT climate trends and variability, for example increased use of artificial snow-making in the European ALPS.

tion:The FIVE basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and PRODUCTS of a given REACTION will allow you to place it into one of these categories. Some reactions will fit into more than one CATEGORY.

1) a) SUBLIMATION b) IRON c) steam d) salt2) a) SOLVENT b) supernatant liquid c) EVAPORATION d) magnetic SEPARATION

tion:Basicity of an acid is the number of HYDROGEN ions which can be produced by one molecule of acid. e.g. Acetic acid is monobasic in NATURE as it can lose one proton or hydrogen ATOM to FORM acetate ion.
