In chemistry, a precipitate is an insoluble solid that emerges from a liquid SOLUTION. The emergence of the insoluble solid from solution is CALLED PRECIPITATION. OFTEN the precipitate emerges as a suspension.Precipitates can form when two SOLUBLE salts react in solution to form one or more insoluble products.

tion:Human beings take food through mouth and digest it in SPECIFIC organs for digestion. The UNDIGESTED food is defecated. The food we take PASSES through a specific canal which BEGINS with BUCCAL cavity and ends at the anus. This canal is called alimentary canal or the digestive tract.

tion:A BALANCE or scale is an instrument used to MEASURE MASS in the science laboratory. One common method of measuring mass is to TARE the scale and measure the mass directly. For example, this is how people weigh themselves. The mass of the SAMPLE is obtained by subtracting the mass of the container.

tion:The main DIFFERENCE between isomorphism and POLYMORPHISM is that isomorphism describes the EXISTENCE of a same morphology in different SUBSTANCES whereas polymorphism describes the existence of different MORPHOLOGIES of the same substance.

tion:tert-Butylamine is an organic chemical compound with the formula (CH3)3CNH2. It is a colorless liquid with a TYPICAL amine-like odor. tert-Butylamine is one of the FOUR isomeric amines of butane, the OTHERS being n-butylamine, sec-butylamine and isobutylamine.

ency of an ELEMENT is dependent on the number of ELECTRONS in the outermost shell of the ELECTRON. In a group all constituting elements will have the same valency because they all have the same number of electrons in the outer SHELLS. Across the a period, the number however increase by 1.Brainliest .. !!

swabbing before an injection is a long-standing, widely used infection control practice. It’s thought that prepping the skin USING ALCOHOL SWABS removes bacteria that COULD be pushed into the puncture and might cause an infection. To clean the skin before vaccination or other injection, suggested standard practice according to the World HEALTH Organisation (WHO) is to swab the injection site with a saturated 60% to 70% alcohol swab for 30 seconds, then let the area dry for another 30 seconds so that the alcohol doesn’t enter the puncture and sting.Here u are mate ... hope u had a good day

Compression molding is used principally for thermosetting plastics, and much LESS commonly for THERMOPLASTICS (for which INJECTION is the PREFERRED method of molding). Extrusion of thermoplastic materials can be accomplished through various means, depending upon the product being manufactured. Explanation:

In CHEMISTRY and PHYSICS, activation energy is the energy that must be provided to COMPOUNDS to RESULT in a chemical reaction.The activation energy of a reaction is measured in joules per mole, KILOJOULES per mole or kilocalories per mole.

(iii) S.I. unit of temperature is KELVIN (K) or absolute degree. (5) Pressure : (i) Pressure of the gas is the FORCE exerted by the gas per unit area of the WALLS of the container in all directions. (ii) Pressure exerted by a gas is due to kinetic energy (KE = (1/2) mv2) of the molecules.

it's option ( 2) 1.6 x 10^ 20.Explanation:atomicity of NO3- = 4NA = 6.023 X 10 ^ 23no.of MOLES = GRAM / molecular mass = 0.0031 / 64        * where ( 1g = 1000mg) Total no.of  e- = moles x NA X atomicity.                         = 0.0031 / 64 x 6 x 10 ^23 x 4                          = 1.6 x 10 ^ 20.

Poor water quality has its most direct impact on aquatic wildlife, particularly fish, bugs, and plants. Excess NUTRIENTS, sediment, road salt, and other contaminants can reduce the variety and hardiness of organisms living in the STATE's waters.Monitoring water quality is an important part of helping us determine WHETHER or not we are making progress in cleaning up our waterways. It reveals the health and composition of STREAMS, rivers, and lakes at a snapshot in time, as well as over WEEKS, months, and years.

The boiling point of a SUBSTANCE is the temperature at which the vapor pressure of a liquid equals the pressure SURROUNDING the liquid and the liquid changes into a vapor. ... For example, WATER boils at 100 °C (212 °F) at sea LEVEL, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude.

6.023×1024 this is the ANSWER

It's OPTION (2) 35 litres.Explanation: *MOLECULAR mass of CAC2 = 64       * NTP = 22.4* GRAM / molelular mass = volume of gas in litres / NTP     100 / 64 =volume of gas in litres / 22.4100 / 64 x 22.4 = volume of gas in litres * volume of gas in litres = 35

ExplanThe Boyle temperature is formally defined as the temperature for which the SECOND virial coefficient, B 2 Since HIGHER order virial COEFFICIENTS are generally MUCH SMALLER than the second In any case, when the pressures are low, the second virial coefficient will be the only relevant one because the  We then have.

ct Question:- Two poles, 13 m and 18 m high stand UPRIGHT on a playground. If their feet are 12 m apart, find the distance between the tops.━━━━━━━━━━━━━━━━━━━━★ Given:-Height of two poles = 13 m, 18 mTheir feet = 12 m★ To Find:-The distance between their tops.★ SOLUTION:- Let AB and CD be two poles of the height 13 m and 12 m and the distance between their feet, BD = 12 m. A || BD.Then, CE = DC - DB = (DC - DE) = (18 - 13) m = 5 mIn right ANGLED ∆AEC, AE = 12 m, CE = 5 mBy Pythagoras theorem, AC² = AE² + CE²⇒ AC² = (12² + 5²) ⇒ AC² = (144 + 25)⇒ AC² = 169⇒ AC² = (13)²⇒ AC = 13Hence, the distance between the tops of the poles = 13 m
