Molarity= moles/liter, so you would need 3mol KBr/1 liter
(0.3M)(1L)= 0.3mol KBr
Unlike solid matter, where particles are tightly packed and slightly vibrating, or gas, where particles go around everywhere and are extremely loose, a liquid has particles that are loosely packed but are still in slight contact with each other. Hope that's good enough
Give 3 Examples of where potential energy was converted to knlinetic energy:
Curtain
A ball before moving
An apple from the tree then falling down
When the Curtains are still, we call the that potential energy. If you move the curtains around, that is kinetic energy
The ball is still, that is potential energy. Then the ball is moving, the is kinetic energy
There is a apple ganging from a tree, that is potential energy. That apple is fall, this is kinetic energy
Hope this helps
Don't type or write in the answer, I'm not sure what from the lab means. These are a few potential into kinetic energy I could have think of!
Answer: Root nodules are associations between bacteria and plant roots responsible for nitrogen fixation.
Explanation:
- As nitrogen present in atmosphere cannot be used by plants directly.
- Nitrogen present in atmosphere is converted into nitrogen compounds by bacteria which is present in root nodules of a plant.
- These compounds of nitrogen are then used by plants for various functions.
