The question is too broad. Depends of the battery and depends where do you connect it to.
define first a battery reaction and where it is connected to define if the reaction is endo or exothermic.
If a battery reaction is exothermic when it is connected to a circuit may be endothermic when it is charged (reverse reaction).
some batteries at low temperature tends to work less, that suggest, they may need absorb some energy from the surroundings.
Answer:
One moves the arm one moves the legs???
Explanation:
Answer:
true
Explanation:
Hotter things have more heat energy than colder things. That's because the atoms or molecules move around faster in hot things (red, right) than they do in cold things (blue, left). ... The more heat you supply, the faster the molecules move and the further apart they get.
Given what we know, we can confirm that the best way to prove that no mass was lost during the reaction would be to follow option C and determine the masses of all substances before and after the reaction.
<h3>Why is this the best method?</h3>
This method provides two sets of data in order to draw a comparison. The other option will either not produce comparable data, or do not take into account all of the elements being produced.
Therefore, by comparing the mass of baking soda and vinegar before the reaction to the mass of carbon dioxide and water after the reaction, we can analyze the differences if any, and confirm that no mass was lost during the reaction.
