Answer:
Friction is "a force which opposes relative motion" while kinetic energy is the "energy an object has associated with its motion." Frictional work will reduce an object's kinetic energy if it opposes the current speed
Explanation:
Option C is correct.
Lactic acid fermentation is a metabolic process in which a glucose molecule turns into lactate which again turn into lactic acid.
In this process a glucose molecule produces 2 molecule of lactate and releases 2 NADH. The NADH is produced from the reduction of NAD+ and ADP takes the phosphates to release 2 molecules of ATP.
In the reaction we gives the magnesium chloride and released hydrogen gas.
The reaction is carried out by contaning positive and negative charged on elements as follows
Mg + HCl --->MgCl2 + H2
Net reaction gives
Mg+ + 2Cl- + 2H+---> Mg+² + 2Cl- + 2H
Check it Mg(s) and Mg2+ not equal . The donor is element while the acceptor is an ion. The same process is done for H2 (g) and H+.
