Answer:
Explanation:
Ionic Compounds Are Balanced
Table salt is an example of an ionic compound. Sodium and chlorine ions come together to form sodium chloride, or NaCl. The sodium atom in this compound loses an electron to become Na+, while the chlorine atom gains an electron to become Cl-
According to the Aufbau principle, , electrons orbiting one or more atoms fill the lowest available energy levels before filling higher levels (e.g., 1s before 2s).
Answer:
C) surface tension
Explanation:
Surface tension is the stretching force on a liquid's surface film caused by bulk liquid particles attracting themselves in the surface layer, which minimises surface area of the liquid.
The surface tension water is high as the strong hydrogen bonds of the on the surface
pull the water molecules together. As such a water drop will tend to occupy the smallest area on the surface.
Water surface tension is 72 dynes/cm at 25°C . That means 72 dynes of force is required to break a water surface film of 1 cm long. Water surface tension varies inversely with temperature. Surface tension of water is as a result of water molecule's polar nature of the and hydrogen bonding.
Answer: The type of deformation in which the object permanently changes size and shape without fracturing is called ductile deformation.
Explanation:
Ductile deformation is when the object bend or flow without fracturing like clay.
On the other hand, when the object breaks is considered brittle deformation.
