According to Newton's third law, forces come in pairs. There is_____and an equal and opposite_____.
hichkok12 [17]

According to Newton's third law, forces come in pairs. There is action-reaction force and an equal (in size - action force) and opposite in direction (reaction force).

<u>Explanation:</u>

On the off chance, when item A applies a force on item B, at that point item B must apply a force of equivalent size and inverse bearing back on object A. This Newton's third law speaks to a specific balance in nature: forces consistently happen two by two.

And, one body can't apply a force on another without encountering a force itself. Now and again, allude to this law freely as activity response, where the force applied is the activity and the force experienced as a result is the response.

The value of h for the reaction below is -73 kj how many kj of heat are released
jarptica [38.1K]
If the value of H is positive, it means you have to add that much heat to complete the reaction. If H is negative, it means that much heat is released during the chemical process. Because it is -73 kJ, 73 kJ of heat are released in the reaction.
