Answer:

Benzoic acid and sodium benzoate are members of a family of food additives whose ability to the rate at which food spoils has helped produce a 10-fold decrease in the incidence of stomach cancer.

A postulate of the kinetic molecular theory is listed.
valina [46]

Answer:

Postulate: Gas particles are extremely small and are far apart.

The activities can be used to demonstrate the postulate is :

<u>Observing colored gas spreading into an inverted jar placed on top of a jar containing the gas</u>

<u />

Explanation:

colored gas spreading into an inverted jar placed on top of a jar containing the gas:

This occur because of two reasons:

1. <em><u>The Gaseous particles are largely spaced . There is large distance between the gases molecule</u></em>

<em><u>2. The gases are in continuous motion . Hence they posses very high kinetic energy . This is the reason they mixes quickly if placed in a jar.</u></em>

<em><u>This occur by the process of diffusion. </u></em>

Diffusion of Gases: The intermixing of particles from the region of high concentration to low concentration.

The coloured gas goes into the space between the gaseous molecule present in the jar.(Gases are far apart)

As soon as the coloured gas is mixed in the jar , It spread quickly by diffusion because , The gaseous particles are extremely small and are far apart.

Can this reaction take place/does it exist - . CaCl2+CO2+H20----&gt; CaCO3 + 2HCl
mash [69]
Yes the reaction given above does exist
First of all CaCl2 will react with  water to form CaO  and HCl  then it will react with CO2 to form <span>CaCO3 
</span>CaCO3 + 2HCl <span>>>></span>     CaCl2+CO2+H20
so i conclude it does exist
hope it helps
