Well, go through the steps. Condensation means? Read the paragraph and find out
It is the physical state of matter from gas phase into liquid phase, and is the reverse of evaporation. Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds
It is a measure of the tendency of an atom to attract a bonding pair of electrons.
Answer: 27 neutrons
Explanation:
Recall that the number of protons in the nucleus of an atom = Atomic number.
Hence, Calcium with mass number 47 and atomic number 20 will have 20 protons
Therefore, since Mass number = number of protons + neutrons
47 = 20 + neutrons
Neutrons = 47 - 20 = 27
Thus, there are 27 neutrons in radioactive calcium nucleus.
Answer:
The prime difference lies in the fact that pure substances cannot be physically separated while mixtures can be. The separation of a mixture into its different parts is done by using physical techniques like distillation, filtering and particle separation.
