Answer: 319.9g
Explanation:
Mass of graduated cylinder with water = 534.26g
Mass of graduated cylinder = 214.36g
Mass of just water = Mass of graduated cylinder with water - Mass of graduated cylinder.
Mass of just water = 534.26g - 214.36 g = 319.9g

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.
