Answer:
When concentration increases, particles collide more often. This is caused by the increased number of particles per unit volume compared to when the concentration is low. For a successful reaction, there must be a collision resulting to the formation of new particles. The higher the rate of collisions the higher the rate of reaction.
The density will not change. Unless you change the mass as well, the volume changing will not change the density
Answer:
One molecule of glucose has 6 atoms, as you can see in carbon's index. ( C6 ). In 20 molecules there will be 6⋅20 carbon atoms.
Explanation:
Answer:
