The SI was established in 1960 by the 11th GENERAL Conference on Weights and Measures (CGPM, Conférence Générale DES Poids et Mesures). The CGPM is the international authority that ensures wide dissemination of the SI and MODIFIES the SI as necessary to reflect the latest ADVANCES in SCIENCE and technology.Explanation:

it means that if the solute is POLAR then the solvent also should be polar which will result in BREAKING of bonds and HENCE it will be dissolved vice VERSA for non polar

The alkalinity of WATER VARIES DUE to the presence of dissolved salts and carbonates, as well as the mineral composition of the surrounding SOIL. In general, the higher the alkalinity, the higher the pH; the lower the alkalinity, the lower the pH ⁶.HOPE IT HELPS YOUMARK ME AS BRAINLIST

ctrolyte in the salt BRIDGE is so chosen that it does not react with any of the CHEMICALS used in the cell.The anion and cation have similar conductivity, and hence similar migratory speed.K+ and Cl− IONS have same IONIC mobilities.So OPTION ( i ) is correct.

AlCl3 + 3H2O → AL(OH)3 + 3HClAluminum CHLORIDE react with water to produce ALUMINIUM HYDROXIDE and hydrogen chloride.

tion:The SOLUBILITY of a given solute in a given solvent typically depends on temperature. For MANY SOLIDS dissolved in LIQUID WATER, solubility tends to correspond with increasing temperature. As water molecules heat up, they vibrate more quickly and are better able to interact with and break apart the solute.

The mass of POTASSIUM Sulphate required to prepare its ten percent(10%) solution in hundred gram(100G) of water is 11.11g. Explanation: Formula: mass of solute/mass of solution×100; A 10% mass solution in 100g of water means X/(100 + x) = 1/10 where x = mass requiredExplanation:

The periodic table is a tabular array of the chemical elements organized by atomic number, from the ELEMENT with the lowest atomic number, hydrogen, to the element with the highest atomic number, OGANESSON. The atomic number of an element is the number of protons in the nucleus of an ATOM of that element.

You need: A cocktail shaker (which can double as a mixing glass), a measuring jigger, a long spoon, a julep strainer. ... GLASSES: A Collins glass, a rocks glass and a COUPE (I'd advise against V-shaped “martini” glasses, which seem to be designed to spill DRINKS.)

The specific heat of a substance is the amount of energy required to raise the temperature of 1 gram of the substance by 1°C. ... The UNITS for specific heat can either be joules PER gram per degree (J/g°C) or CALORIES per gram per degree (cal/g°C). This text will USE J/g°C for specific heat.

ZnExplanation:ZN is the SYMBOL of ZINC.

Organotin compounds or stannanes are chemical compounds based on tin with hydrocarbon substituents. Organotin chemistry is part of the wider field of organometallic chemistry. The first organotin compound was diethyltin diiodide ((C2H5)2SnI2), DISCOVERED by Edward Frankland in 1849.[1] The area grew rapidly in the 1900s, ESPECIALLY after the discovery of the Grignard reagents, which are useful for PRODUCING Sn-C bonds. The area REMAINS rich with MANY applications in industry and continuing activity in the research laboratory.[2]

Irrigation helps to grow agricultural crops, MAINTAIN LANDSCAPES, and revegetate DISTURBED soils in dry areas and during PERIODS of less than average rainfall. Irrigation ALSO has other uses in crop production, including frost protection, suppressing weed growth in grain fields and preventing soil consolidation.

pH is just a measure of the concentration of H+, it tells you NOTHING about the ACIDITY of the individual acid molecule. You need to know the concentration of each solution as WELL as the pH to determine which molecule is stronger/weaker in TERMS of acidity (which can be expressed in terms of pKa VALUES).

istance is the RATIO of the length and cross-section area of the conductor, whereas the resistivity of the MATERIAL is the ratio of the PRODUCT of the RESISTANCE and area to the length of the conductor. The resistance is represented by the symbol R whereas the resistivity is represented by the symbol ρ.

Meyer is the best known for his parts in the periodic CLASSIFICATION of elements. He noted J.A.R. New lands did in England , if each element is arranged in the order of their atomic weighs, they FALL into GROUPS of similar chemical and physical PROPERTIES related at periodic intervals.

Solution of SALT in water is a MIXTURE and not COMPOUND because salt solution is made up of salt and water, MIXED physically. ... Salt solution does not have fixed properties. Its properties depend on the nature of its COMPONENTS and the ratios in which they are mixed.
