Answer:
2%
Explanation:
.98 is 98% of one and therefore they are missing 2%
Answer:
gaseous CO2 bubbles out of the solution
Explanation:
We already know that the dissolution of a gas in water is exothermic. Hence, when the temperature of a solution containing a gas is increased, the solubility of the gas decreases and the gas bubbles out of the solution.
Similarly, the dissolution of KNO3 in water is endothermic. This implies that the solubility of the solid increases with increasing temperature.
Thus the solid becomes more soluble at 75°.
Explanation:
When water vapour changes to liquid water then this process is known as condensation.
For example, when lid is placed in a hot water filled pan then after sometime vapours appear on the surface of lid. When temperature of water decreases then water vapours convert into liquid form.
Thus, we can conclude that in condensation water vapor changes to liquid water.
A - its condensation and gas particles have a higher kinetic energy
Carbon can react with oxygen to form carbon dioxide. Which of the following statements about this chemical change is true? ... Carbon and oxygen atoms are destroyed as new atoms are formed. Carbon and oxygen atoms have the same properties as molecules of carbon dioxide.
