Answer:Tungsten changes oxidation numbers +6 to zero
Undergoes reduction
Explanation:
did it!
Valence electrons are the electrons in the outermost shell of an element on the periodic table. Atoms want to be able to have a full outer shell and they can share or trade electrons in order to achieve this. Valence electrons are also super super important in chemical reactions. The number of valence electrons determines what group that specific atom or element is in on the periodic table. This affects the reactivity of the element.
Limitations of Van der waal's equation. (i) The value of 'b' is not constant but varies with pressure and temperature. (ii) The value of is not equal to 3b, but actually it is equal to, in some case; and in other cases 2b. (iii) The value of is not equal to but it is usually more than 3 for most of the gases.
Answer:
b. atomizes liquids into small solid particles
Explanation:
Spray drying -
It refers to the process of getting a dry powder from the liquid or the slurry ,with the help of hot gas , is referred to as spray drying .
The method is used in the field of pharmacy .
It is a type of atomizer or spray nozzle which helps to disperse the liquid into the controlled drop size spray .
Small solid particles are generated by this method .
Hence , from the given scenario of the question ,
The correct answer is b. atomizes liquids into small solid particles .
