fibres are called as SYNTHETIC fibers because these are manmade fibers prepared by using chemicals. These are MADE of small units that join together to form long chains.2.It is made from purified cellulose from wood pulp which is converted into soluble compound which is chemically solidified to form synthetic fiber. Because rayon is manufactured from naturally occurring polymers, it is CONSIDERED a semi-synthetic fiber.3.a) Synthetic fibres are also called man-made or artificial fibres.b)Synthetic fibres are synthesised from raw material called PETROCHEMICALS. c).....a)Synthetic fibres are also called artificial or manmade fibres. (b) Synthetic fibres are synthesised from raw material called petrochemicals. (c) Like synthetic fibres, plastic is also a polymer.hope it helps you......

That is because when it reaches the BOILING POINT or melting point , the substance starts changing into other state , for eg : water when reaches 100 C it starts melting ie changing it's state so the temperature at that moment remains constant .That is because when it reaches the boiling point or melting point , the substance starts changing into other state , for eg : water when reaches 100 C it starts melting ie changing it's state so the temperature at that moment remains constant .Explanation:HOPE its help you

In chemistry, VALENCE BOND (VB) theory is one of the two basic theories, along with molecular orbital (MO) theory, that were developed to use the methods of quantum mechanics to EXPLAIN chemical bonding. It FOCUSES on how the atomic orbitals of the dissociated atoms combine to give INDIVIDUAL chemical bonds when a molecule is formed. In contrast, molecular orbital theory has orbitals that cover the whole molecule.I hope you got your answer. ◉‿◉

The law of reciprocal proportions was proposed by Jeremias Ritcher in 1792. It STATES that, "If two DIFFERENT elements combine separately with the same WEIGHT of a third element, the ratio of the MASSES in which they do so are either the same or a simple multiple of the mass ratio in which they combine."Explanation:plzzz mark me brainlist

A collage may sometimes include magazine and newspaper CLIPPINGS, ribbons, paint, BITS of colored or handmade papers, portions of other artwork or texts, PHOTOGRAPHS and other found objects, glued to a piece of paper or canvas. The origins of collage can be traced back hundreds of years, but this technique made a dramatic reappearance in the EARLY 20th century as an ART form of novelty.

We KNOW that :N1V1=N2V2Normality=Molarity×BasicityFor SULPHURIC ACID, the BASICITY is 2.∴N1=0.1×2=0.2NV1= ?N2=0.1×1=0.1NV2=40ml0.2×V1=0.1×40V1=20ml

46.07 g/molMelting point: -114.1 °CDensity: 789 kg/m³Formula: C2H5OHExplanation:ANSWERMolar mass of ETHANOL (C 2 H 5 OH) =2(12)+6(1)+16.1=46.1 g/molHence the correct option is C.follow me and MAKE me brainliest PLEASE...

Explanation:Molecular mass of H2SO4 is 98 gm.So if you are asking no. Of moles of Hydrogen gas (H2) then one MOLE of hydrogen gas will contain two mole of hydrogen atoms.Now SINCE 1 molecule of H2SO4 contain two hydrogen atoms thus 1 molecule of hydrogen gas (H2). THEREFORE 98 gm(1mole) of H2SO4 will contain one mole of H2 gas. And two moles of Hydrogen atoms.

Given : The perimeter of a sector of a circle of radius 14 CM is 68 cm.To Find : The area of the sector ?Solution :Perimeter of a sector = Twice of radius + LENGTH of arci.e. P=2r+lP=2r+l68=2(14)+l68=2(14)+ll=68-28l=68−28l=40l=40The length of arc is 40 cm.The formula of length of arc is l=\frac{\theta}{360}\times 2\pi rl= 360θ ×2πr40=\frac{\theta}{360}\times 2\times\frac{22}{7}\times 1440= 360θ ×2× 722 ×1440=\frac{\theta}{360}\times 8840= 360θ ×88\theta=\frac{40\times 360}{88}θ= 8840×360 \theta=\frac{3600}{22}θ= 223600 The area of the sector is A=\frac{\theta}{360}\times \pi r^2A= 360θ ×πr 2 A=\frac{\frac{3600}{22}}{360}\times\frac{22}{7}\times 14\times 14A= 360223600 × 722 ×14×14A=280\ cm^2A=280 cm 2 THEREFORE, the area of the sector is 280 cm².

CHEMISTRY4.4 g of a gas at STP occupies a VOLUME of 2.24 L. The gas can be: Help BEST friendStudy laterANSWER 4.4 g of a gas at STP occupies a volume of 2.24 L. The gas can be CO 2 At STP, 1 mole of any gas occupies a volume of 22.4 L. 4.4 g of a gas at STP occupies a volume of 2.24 L.Hence, the NUMBER of moles of gas = 22.42.24 =0.1 moles.0.1 moles of a gas = 4.4 g.1 mole of a gas =4.4× 0.11 =44 g.Thus, the molecular weight of gas is 44 g/mol. It is the molecular weight of CO 2 gas.

It's easier to navigate the PERIODIC table and write chemical equations and formulae once you know the symbols for the elements. HOWEVER, sometimes it's easy to confuse symbols of elements with similar names. Other elements have symbols that don't seem to relate to their names at all! For these elements, the symbol usually refers to an older ELEMENT name that isn't USED anymore.

Which of the following property is generally not shown by metals? EXPLANATION: Metals have SHINY APPEARANCE and not dull. Thus property of dullness is not shown by metals. Explanation: Dulctility is one of the properties of metals which enable metals to be DRAWN into thin wires.

The ocean formed billions of years ago.Over vast periods of time, our PRIMITIVE oceans formed. Water REMAINED a GAS until the Earth cooled below 212 degrees Fahrenheit . At this time, about 3.8 BILLION years ago, the water condensed into rain which filled the basins that are now our oceans.please mark me as the brainliest.
