Pliz , i need help, answer all my question,

1. When two or more compounds mix, they form a mixture. And water is a mix of hydrogen and oxygen bonded together through chemical bonds. ... It has 2 atoms of hydrogen covalently bonded to one atom of oxygen. This means it cannot be separated by physical means, unlike a mixture.

2. To summarize, evaporation is slower, occurs only from the surface of the liquid, does not produce bubbles, and leads to cooling. Boiling is faster, can occur throughout the liquid, produces lots of bubbles, and does not result in cooling. Evaporation is a normal process that occurs when the liquid form changes into the gaseous form; while causing an increase in the pressure or temperature. Boiling is an unnatural process where the liquid gets heated up and vaporized due to continuous heating of the liquid.For example, a puddle of water will evaporate on a cold day, though the rate of evaporation will be slower than it would be on a warm day. In contrast, boiling only occurs at the boiling point of the liquid. An example of condensation can be seen when drops of water form on the outside of a glass of ice water.

3. a.) Decantation can be used to separate immiscible liquids that have different densities. For example, when a mixture of water and oil is present in a beaker, a distinct layer between the two consistency is formed, with the oil layer floating on top of the water layer. b.) ea leaves can be isolated from tea by the filtration method. c.)Fine mud particles suspended in water – settling down with time or centrifugation. Usually mud particles are dense enough to settle down from water, if the vessel is left undisturbed for some time. But for a faster separation, centrifugation can be opted for which quickly settles down the mud particles as pellet

4. a.) Saturated Solution. A solution with solute that dissolves until it is unable to dissolve anymore, leaving the undissolved substances at the bottom. b.) a homogeneous noncrystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle, and cannot be separated out by ordinary filtering or centrifuging like those in a suspension. c.) suspension is a heterogeneous mixture that contains solid particles sufficiently large for sedimentation

5. Homogeneous mixtureHeterogeneous mixture

It has a uniform compositionIt has a non-uniform composition

It has only one phaseThere are two or more phases

It can't be separated out physicallyIt can be separated out physically

'homo' means the same'hetero' means different

6. 16 g of sulphur = 16 256 1 16 = moles = 0.125 moles 1 mole of S8 molecules = 6.023 × 1023 number of molecules ∴ 1 16 mole of S8 = 6.023 × 1023 number of molecules × 1 16

7. It is given that the ratio of hydrogen and oxygen by mass to form water is 1:8. Then, the mass of oxygen gas required to react completely with 1g of hydrogen gas is 8g. Therefore, the mass of oxygen gas required to react completely with 3g of hydrogen gas is 8 × 3g = 24 g.

serve the people! ,” smoothly translated by julia lovell, offers an initial sample of yan lianke’s writing to an english-speaking audience. a bluntly drawn, mildly erotic fable, it teases mao zedong by poking fun at a true believer who obeys the chairman’s precepts too literally. to a western sensibility, the broad strokes of yan lianke’s humor would seem to pose little risk of inciting rebellion, whether of the flesh or of the body politic. but then, part of the book’s attraction is that it doesn’t have a western sensibility. it lets the reader see — or rather, intuit — what jokes chinese officials don’t consider funny, and how very little it takes for a writer to be branded an incendiary in 21st-century china, more than three decades after the death of mao, a decade after the death of deng xiaoping and seven years since china entered the world trade organization, a move that would seem to signal a willingness (however wary) to mingle with the rest of the world.
