Answer:
The rate determining step is step 1
Explanation:
Intermolecular force for solids is high. Whereas low in gases. The smell of agarbatti spreads immediately because the molecules of air diffuses very fastly.
The melting point of potassium = 
Melting point of titanium = 
Titanium has a stronger metallic bonding compared to potassium. Titanium being a transition metal has greater number of valence electrons (4 valence electrons) contributing to the valence electron sea compared to potassium which has only one valence electron. The atomic size of Titanium much lower than that of potassium, so the bonding between Titanium atoms is stronger than that of potassium. Hence, the melting point of Titanium is much higher than that of potassium.
Question:
Layer 1 and 2 → Animal fossil
Layer 3 and 4 → First plant fossil
Layer 5 → Animal fossil
Layer 6→ Second plant fossil
Layer 7 → Animal fossil.
Answer:
The correct option to choose answer is;
C) Layers 3 and 4 (Secondary succession layer).
Explanation:
Secondary succession is a concept related to pliant life and it describes the notion of an ecosystem regenerates after being destroyed and it takes place when the level of disruption is not enough to do away with all present vegetation and present soil from a location.
Secondary succession is started by an incident that destroys to a large extent the present ecosystem. Events that start secondary succession includes;
1) Hurricane
2) Fire and
3) Harvesting.
