Answer:
The correct answer is a. The volume of the gas increases.
Explanation:
In this case, we apply Boyle Mariotte's Law: for a given gas mass at constant temperature, the pressure and volume vary inversely proportionally (the higher the pressure, the lower the volume and vice versa).
If the pressure reduced, the volume increases according to the formula: P1xV1 = P2xV2
NH₃(aq) + HNO₃(aq) = NH₄NO₃(aq)
Ammonia is a weak base. The reaction of ammonia and nitric acid is a neutralization reaction.
NH₃ + H₂O = NH₄⁺ + OH⁻
HNO₃ + H₂O = H₃O⁺ + NO₃⁻
OH⁻ + H₃O⁺ = 2H₂O (neutralization)
The one with 20 coils as it can generate more electricity.
Answer:
Endothermic reactions are reactions that require external energy, usually in the form of heat, for the reaction to proceed. In order to melt the ice cube, heat is required, so the process is endothermic. Endothermic reactionIn an endothermic reaction, the products are higher in energy than the reactants.
Explanation:
I believe Jose is correct because though the book isn't moving, gravity is still being applied (gravity counts as force)
