Answer:
In a redox reaction, a reducing agent will donate electrons to another chemical species and then it becomes oxidized.
Explanation:
A redox or oxidation-reduction reaction is a chemical reaction where exchange of electron(s) happen between two chemical species (molecule, atom or ion). In this reaction, one chemical species act as an oxidizing agent while another will be a reducing agent.
An example of redox reaction is given in the attachment.
In a redox reaction, the oxidation number of a reducing agent will be increased, whereas oxidizing agent will be reduced.
The correct chronological order in which an earthquake occurs.
1. The plate suddenly move.
2. Stored energy is released in the form of seismic waves.
3. Due to the movement in the mantel, compression goes on increasing.
4. The earth surface vibrate.
When the plate move from the surface of the earth, all the stored energy present in it is usually released in the form of seismic energy waves and due to the movement in the mantel, compression goes on increasing, then after , the earth surface vibrate.
Hope it has helped:-)
To determine the reason for the fish death, do the following:
1. Test the water for the presence of organic substances that may be poisonous to the fish.
2. Test the dissolved oxygen concentration of the lake at different locations and at different depths.
3. Perform full toxicological examination of the lake to determine if any pollutant or poisonous chemical is present in the lake.<span />
