Concept:
When an atom has incomplete number of electron in its outermost orbit then it has great tendency to react with another atom which satisfies their octate either by sharing or by transferring their electrons. The involved electrons are called valence electrons.
In case of electrovalent compound, the valance electron complete their octate by transferring their valence electrons while in the covalent compound, they complete their octate by the sharing of their valence electrons.
Hence, the valence electron of the atom is involved in chemical bonding with other atoms.
<span>A substance dissolves in water by breaking up into smaller pieces. these pieces of the same substance spread throughout the water. this process is known as d</span>iffusion.
In short, your answer would be : Diffusion.

You didn't give options but seedless vascular plants are plants that contain vascular tissue, but do not produce flowers or seeds so for example ferns and horsetails
Answer:
0.55
Explanation:
When multiplying values, the number of significant figures in the answer should be the same as the number with the lowest sig figs in the problem which in this case is 2 sig figs (0.17)
3.22 * 0.17 = .5474
Rounded to 2 sig figs = 0.55
Answer:
6.37 L
Explanation:
- Used combined gas law. Get rid of temperature since it is constant. (You could also keep it and get the same answer, but it is another step)
- Change C to K
- Change torr to atm
- Hope this helps! I would be glad to give you a step by step explanation. Please let me know if you want help on how to do these types of problems.
