Explanation:
an increase in concentration increases the rate of the reaction. This is because there are more reactant particles available which allows for more effective collisions between reactant particles in a given period of time. More effective collisions bring about a faster rate of reaction.
Answer:
A.
Explanation:
A redox reaction is a reaction when oxidation states (or numbers) change during reaction.
Answer:
Explanation:
Hello there!
In this case, since the titration of acids like KHP with bases like NaOH are performed in a 1:1 mole ratio, it is possible for us to know that their moles are the same at the equivalence point, and the concentration, volume and moles are related as follows:
Thus, by solving for the volume of the base as NaOH, we obtain:
Best regards!
Answer:
1.Balance the equation.
2.Convert units of a given substance to moles.
3.Using the mole ratio, calculate the moles of substance yielded by the reaction.
4.Convert moles of wanted substance to desired units.

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.
