Answer:
exothermic
Explanation:
This is an exothermic reaction because you can see the 232.4 kJ at the end of the reaction. That means that 232.4 kilo-joules are released when the reaction happens; when energy is released during a reaction, the reaction is exothermic.

Answer: To represent conservation of mass.
Explanation:
As the law given by Antoine Lavoisier which states that " in a chemical reaction, mass before and after the reaction remains the same that is mass remains conserved in a chemical reaction" which is known as Law of Conservation of Mass.
Total mass of the reactants = Total mass of the products
So, in order to represent the conservation of mass chemical equation should always be balanced.
An organelle could be the nucleus of a cell.
The nucleus of a cell would be comparable to the nervous system in the body, which is considered an organ system.
Hope this helps!
Answer:
D: Increasing the amount of water.
Explanation:
Choice A: increasing the pressure can force the liquid to stay a liquid and affect the boiling point (decrease it).
Choice B and C: both involve colligative properties, adding a solute to water will increase the boiling point of water.
Choice D: just having more water does not change the boiling point of the water as this minimize the effect of any external factor.
<em>So, the right choice is: D: Increasing the amount of water.</em>
