1)Na and O - ion bond
2)K and F - ion bond
3)Ne and O - no bond (as Ne is a noble gas)
And by elimination, your answer is 4)
The correct combination of <span>theoretical motions of particles with their associated phases is given below:
1) Solid : </span>
oscillation about a fixed point . Because solids do vibrate (atoms/molecules of a solid oscillate around their mean positions)<span>
2) Gas : </span>
translation, vibration, rotation. The gas molecules are free to rotate, oscillate & vibrate. <span>
3) Liquid: </span>
rotation and vibration. The liquid molecules are free to rotate & vibrate.
A more clear pictures (at atomic & molecular level is shown below):
A a solid is the correct answer
Answer:
No
Explanation:
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture.
