milk and air is a mixture
Answers
Answer:
Air and Milk both are mixture
Explanation:
Milk : Milk is not a pure substance; it is considered a mixture because it does not occur naturally on its own. It is a mixture that combines mostly water, sugar, fat and proteins. Most substances found in the world are not pure substances but are a combination of various chemicals and compounds.
Air : Air is mixture, but not a compound because of the following reasons: Air can be separated into its constituents such as oxygen, nitrogen, etc. by fractional distillation of liquid air. Air shows the properties of all gases present in it.
Answer:
air and milk or both mixtures
> Air is a homogenous and colourless mixture consisting of gaseous nitrogen (N2
), oxygen (O2
), carbon dioxide (CO2
), argon (Ag) and some trace amounts of water vapour, methane (CH4
), ammonia (NH3
), etc. Air is considered as a mixture because of the following reasons:
> It is possible to separate air into its constituent gases by means of physical methods like fractional distillation. The boiling point of nitrogen (77.3 K) is less than that of oxygen (90 K). So, when liquefied air is distilled, nitrogen is separated out first and oxygen is left in the mixture. No energy or heat is either absorbed or evolved while mixing gases.
> The identities of the constituent gases in air are retained. That is why air shows the chemical and physical properties of all the gases present in it. For example, CO2
in air can slowly turn the lime water Ca(OH)2
dissolved in water) milky like pure CO2
does following the chemical reaction
The fresh milk that comes from cows is a mixture of water, fat (also called butterfat or milkfat), and milk solids. The milk solids are made of proteins and carbohydrates. The major milk protein is casein, which is dispersed throughout the milk. Lactose is the primary carbohydrate found in milk. The enzyme lactase is used by the body to break the lactose down to galactose and glucose, two simple sugars that the body can digest.
