Explanation:
When work is done then there will occur change in volume. And, most change in volume occurs when there will be production of gas is taking place. We assume that no work is done when no gas is produced.
(a) For
Here, 3 moles of gas is producing 0 moles of gas. This means that work is done on the system.
(b) And, more is the production of a gas taking place in a reaction more will be the amount of work done by the system.
For
Here, 2 moles of a gas is producing 3 moles of a gas. Since, gas is increasing so, work will be done by the system.
Answer:
the correct answer would be B(diffusion). please mark brainliest
Explanation : diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. the smell simply moves around the room. hopefully this helps
The element which can not loose electron easily and having electronagtive character is called non-metal it has following property-1. it can not conduct heat and electricity1. it is netiher ductile not malleable3. it is not lsuturous and also not sonorous
As atomic radius decreases, electronegativity <u>increases</u>. This is mostly because a smaller atomic radius represents a <u>stronger</u> hold on the valence <u>electrons</u>.
