Answer:
Combination and redox
Explanation:
8Zn(s) + S8(s) → 8ZnS(s)
This is a combination (synthesis) reaction because two elements are combining to form a compound.
It is also an oxidation-reduction (redox) reaction, because the oxidation number of Zn increases from 0 in the metal to +2 in the compound (oxidation), while the oxidation number of S decreases form 0 in the element to -2 in ZnS (reduction).
Some of the many types of reaction are:
- combination
- decomposition
- single decomposition
- reduction
- oxidation
- reduction-oxidation
- precipitation
Answer:
Only Organism Z is alive, and Organism X has been dead longer than Organism Y.
Explanation:
After the death of an organism, there is radioactive disintegration of C-14 allotrope of carbon, which increases the ratio of C-12 to C-14 in a dead organism as compared to a living organism.
Answer:3 moles
Explanation:
For every three molecules of CO2 that enters the Calvin cycle, one molecule of the three carbon glyceraldehyde 3-phosphate (G3P) is produced. Two molecules of G-3-P are required to produce one molecule of glucose. Therefore, the Calvin cycle needs to make a total of 6 turns to produce two molecules of G-3-P.
