Answer:
Increasing the temperature will cause chemical changes to occur faster. Decreasing the temperature, causes the particles to lose energy which causes them to move around less and slower. The less they move, the less collisions occur, and the less reactions occur between the chemicals = slower reaction rate.
Explanation:
I suppose you mean to ask why we can't go through obstacles.
Any atom is surrounded by an electronic cloud. When two atoms get close to each other, the electronic clouds repel each other, preventing them from interpenetrating each other. That same phenomenon, on a larger scale, prevents us from going through matter.
1) same amount of carbon atoms.
That is why it is still called butane and butene.
but- always signifies 4 carbons
THey can move around each other instead of just vibrating in place like solid prticles.
This is true
Because when water evaporates molecules break and separate into different atoms
