Answer:
A. Oxygen puts off carbon dioxide.
Explanation:
Answer:
1) B. increases
2) B. greater
3) C. Both A and B are correct
4) Activation energy
Explanation:
The rate of a chemical reaction is depend on temperature. If temperature increases, the chemical reaction also increases and vice versa. Fast reaction means which is completely in less time. So atoms in fast reaction have great activation energy and slow reaction have less activation energy. Collision occurs when the particles have energy to move and they collide in proper direction.
The answer is to increase the surface area of the solute.
You see it dissolves faster because there is a lot more water touching it when it is has a higher surface area.This can be achieved by crushing
It's -Bohr's Model- becuase Dalton I dont think did a model. Thomson's was the "Plum Pudding Model." Ernest Rutherford drew one out(I dont know i dont have a model down though) so it the only one left is Dalton's Model which is it. (Hopefuly)
B and C have the same atomic numbers, which means they have the same number of protons, which is the defining part of an element.
