<u>Answer:</u> <em> Option (A)</em>
<em>Larger molecular weight means a smaller valence or charge on the metal, so making the bond between them weaker and the hardness lower</em>
<u>Explanation:</u>
<em>Hardness decrease with increasing molecular weight of the metals</em> in the oxygen compounds, the reason for the decrease in hardness of the metals is due to chemical repulsion (inter molecular forces between atoms) which is greater when the metal and oxygen are close to each other <em>making the compound hard.</em>
If the repulsion is smaller, the compound has less hardness. So when the molecular weight is large, it has smaller valence or less charge on the<em> metal which makes the bond weaker and less hard.</em>

A fundamental concept of ecology is that living organisms are both similar to and different from each other and from nonliving things.
Living things are similar in that they rely on many of the same processes to stay alive, yet are different in the ways that these processes are carried out.
Non living things lack certain features of living organisms, such as the ability to maintain a cellular organization, carry out metabolic activity while maintaining internal stability (homeostasis) and pass on hereditary information through reproduction.
Answer:
A. Tsunamis:
Tsunamis usually cause the greatest amount of destruction in comparison to other waves. There are massive waves that can cause the destruction of most ecosystems.
Explanation:
- Tsunamis cause large displacement of the water bodies and are generally known as the killer waves.
- The tidal waves are a regular recurrent shallow body of water and affect the gravitational attraction between the sun and the Sun, Moon and the earth and maybe often referred to as tsunami but do not generate to the small tidal waves
- The wind-driven waves or the surface waves are those created by the formation of the surface water and them tens to blow away the occurs for the Oceana and are found across the open seas and globally across the coast. As compared to the tsunami that is tectonically produced these are due to the disturbance in the body of the water.
