Answer:
Sprockets.
Explanation:
A chain drive is an efficient technique used for the transmission of mechanical power from one point to another. For example, it is used for transmitting power to the wheels of a bicycle, motorcycle, motor vehicle and other machineries such as chain saw etc.
Chain drive ratio is the ratio between the rotational speeds of the input and output sprockets of a roller chain drive system. This ultimately implies that, chain drive ratio is the ratio of the number of teeth on the driving sprocket (T1) divided to the number of teeth on the driven sprocket (T2).
Also, the chain drive ratio can be calculated by dividing the number of teeth on the large sprocket by the number of teeth on the small sprocket.
Additionally, the rotational speed of a sprocket is measured in revolutions per minute (RPM).
One of the issues with the roller chain is that, as the roller chain moves round the sprocket link by link, it affects its speed (surge) due to the change in acceleration and deceleration i.e the rise and fall of its pitch line.

Answer: The size of the ion and the charge of the ion are the factors that affect solubility in water.
Explanation:
Lead lose electrons to become cations. Compounds with small ions tend to be less soluble than compounds with large ions. Large ions have higher solubility. This is because small ions are closely packed so it is difficult for water to break them apart.
Compounds with small ions seemingly have less solubility than those with large ions. The ions in the compound attract each other, and the water molecules attract the ions. Compounds would be soluble in water If the water molecules have a greater or higher attraction to the ions than ions have for each other.
