Heat
Explanation:
if I hold a beaker during a reaction that is supposedly an exothermic reaction, I will feel that the heat of the beaker. In exothermic reaction, the environment becomes hotter at the end of the change.
- Exothermic reaction is a type of enthalpy change.
- In this kind of reaction, heat is liberated to the surroundings.
- Here, the surrounding becomes hotter at the end of the changes.
- Change in enthalpy is assigned a negative value as the sum of heat contents of products is less than that of the heat content of reactants.

Answer: Sound waves are sound and oceans waves are water waves. Water waves are bigger
Explanation:
Answer: In asexual reproduction, the genetic material of the parent cell doesn't combine with that from another cell. The simplest method of reproduction that algae employ is asexual binary fission, in which a cell splits into two, either at the equator or along its length.
Answer:
- <em>The partial pressure of the oxygen gas is </em><u>96.00 KPa</u>
Explanation:
The law of partial pressures states that, in a mixture of gases, the total pressure of the mixture is equal to the sum of the individual pressures of each gas, as if each gas were alone in the mixture.
So:
- Total pressure = ∑ individual pressures
- Total pressure = Partial pressure of the water + Partial pressure of oxygen
- 98.67 KPa = 2.67 KPa + Partial pressure of oxygen
- Partial pressure of oxygen = 98.67 KPa - 2.67 KPa
- Partial pressure of oxygen = 96.00 KPa ← answer
