Answer:
A system absorbs more energy than it releases and has a positive AH
Explanation:
Answer:
Explanation:
Endothermic (endo = into + thermic = heat) means that heat energy is going into a system.
The products will have more energy than the reactants and ΔH will be positive.
A is wrong, because ΔH is positive.
C and D are wrong, because the system absorbs more energy than it releases.

Answer:</h3>
one battery, two switches, and three light bulbs
Explanation:
- A circuit is an arrangement that shows the flow of electrons from a current source such as a battery.
- The diagram shows a circuit that contains one battery, two switches, and three light bulbs.
- The switches serves to close the circuit when necessary.
- The battery supplies current to the circuit.
- The light bulbs are used for lighting.
The chemical activity series is the arrangement of the elements descendingly according to their chemical activity for reactions like simple substitution reactions and redox reactions. Elements above hydrogen can replace hydrogen from water and acids as they are more active than hydrogen. Since cesium is more active than hydrogen, it replaces it in hydrochloric acid.
2 cesium atoms loses 2 electrons first;
2Cs --> 2Cs+ + 2e-
2 hydrogen atoms recieve the two electrons;
2H+ + 2e- --> H2
The net ionic equation is;
2Cs + 2HCl --> CsCl + H2
Answer:
Fermentation
Explanation:
If your body were to break down glucose with the use of oxygen then it would be aerobic, but since oxygen isn't being used in this case, the process would be anaerobic or fermentation.
Hope this helps :)
