Answer:
The answer is D, organisms that are mostly related belong in a species.
Explanation:
Answer:
Overall reaction
H2(g) + 2ICI(g) -----> I2(g) +2HCl(g)
Overall Rate = k1[H2] [ICl]
Explanation:
Overall reaction
H2(g) + 2ICI(g) -----> I2(g) +2HCl(g)
The overall reaction is the sum of the two two reactions shown in the question. After the two reactions are summed up properly, this overall reaction equation his obtained.
Since K1<<K2 it means that step 1 is slower than step 2. Recall that the rate if reaction depends on the slowest step of the reaction. Hence
Overall Rate = k1[H2] [ICl]
Answer:
Chemistry has taught that ;
Unsaturated hydrocarbon molecules that contain one or more double bonds are called alkenes.
Alkynes are unsaturated hydrocarbons due to the fact that some of the carbons are connected to fewer than four neighbouring atoms.
Note : Alkenes contain at least one double bond, while alkynes contain at least one triple bond.
Explanation:
Answer:
- From octane: 
- From ethanol: 
Explanation:
Hello,
At first, for the combustion of octane, the following chemical reaction is carried out:
Thus, the produced mass of carbon dioxide is:
Now, for ethanol:
Best regards.
