Answer:
An applied force is an interaction of one object on another that causes the second object to change its velocity. A resistive force passively resists motion and works in a direction opposite to that motion. An inertial force resists a change in velocity.
Explanation:
The volume of water he dissolved the solute is 250 cubic centimeter.
<u>Explanation</u>:
Concentration = mass of solute in g / volume in dm^3
The concentration of a solution is defined as the ratio of mass of solute in grams to the volume of water in dm^3.
If concentration of a solution = 8 g/dm^3.
mass of solute =2 g.
Volume of a water = 2 / 8 = 0.25 dm^3. (or) 250 cubic centimeter.
My number one tip is to STUDY! I know it sucks, but once you're in high school, it's going to become a part of your routine every single day. Even if you study right now, keep on doing it over and over and over. Trust me! It'll help. Also, get a tutor! Maybe someone you know is doing well and you could ask them to help, or you could ask a student who was in your class and passed. My number one advice is to just keep working hard. I get it; chemistry is HARD. You'll get there!
According to data the structures are as drawn below.
Lewis structure is drawn by adding valence electrons of all elements present in a given compound.
In this case,
6 + 6 + 4 = 16 valence electron
secondly, the central atom is drawn in center and other outside, like carbon in center.
Then single bonds are drawn to connect the central atom to side atoms and 2 electrons for each single bonds are subtracted from total electrons, in this case 16-4=12, these 12 electrons are added to the most electronegative atoms, in this case to oxygen atoms. After that changes are made in a uch a way that each atom gets a complete octet number (8 electrons).
So, Among these three structures only the Blue structure is correct because in it each atom has a complete octet. While in other two oxygen or carbon has deficiency of electrons.
