IV. Challenge
1. In aerated drinks, mostly it is carbon dioxide gas that is dissolved. Can you tell how is carbon
dioxide dissolved in the drinks?
2. Are all fluids liquid? Explain.
3. Is law of conservation of mass applicable to burning of fuels too?
4. Does the law of conservation of mass hold good in case of gaseous reactants and gaseous products
also?
5. Air is a mixture of gases. Can it be compressed or expanded?
Answers
Answer:
1. Carbon dioxide gas is comparatively more stable and better dissolves in water rather than other common gases. Moreover, addition of the gas gives the drink the fizziness which in other ways react with water to form carbonic acid which in turn produces a lemonish flavour.
2. All liquids are fluid. A fluid is a substance that lacks rigidity it cannot resist force when it is applied to it. Liquids can assume the shape of any container or vessel, and they are relatively incompressible. These are some differences between fluid and liquid.
3.The law of conservation of mass is applicable to burning of fuel too, as the gases released in the process have the same mass as the fuel.
4.According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants. The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction.
5.The pressure in most commonly used scuba tanks ranges from 200 to 300 atmospheres. Gases are unlike other states of matter in that a gas expands to fill the shape and volume of its container. For this reason, gases can also be compressed so that a relatively large amount of gas can be forced into a small container.
Mark me as brainliest..
plz
i beg u
Hope u like my answer..
Answer:
1. carbon dioxide gas is dissolve inherited drinks at cold temperature and very high temperature erated drinks contain compressed carbon dioxide that gives them the fizz.
2. no all friends are not liquid because gases can also flow like that of the liquid from high level to lower level.
3. no the law of conservation of mass is not applicable to burning of fuel in open container because the product gases formed escapes out and the weight of the reactant and the products is not equal but if we consider it in a closed container than burning of fuel also prove the law of conservation of mass as the mass of reactants is equal to the mass of the products.
4. yes the law of conservation of mass states that matter cannot be created nor be destroyed if it is in closed container.
5. yes air is a mixture of gases it can be compressed but in reality it cannot be expanded.

i have a question to you ! is this the question and answers of class 8th challenge question of chemistry of Cambridge connection.?? are you a student of Carmel school
