i didnt do dis my mom has a answer key book
Explanation:
Answer is: B because it has a lower activation energy.
For all chemical reaction some energy is required and that energy is called activation energy (energy that needs to be absorbed for a chemical reaction to start), activation energy for reaction B is lower that for reaction A.
Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst.
Chemical reactions occur faster with a catalyst because they require less activation energy.
Answer:
3 is the coefficient in front of the
The smallest whole-number coefficient is 2.
Explanation:
The balanced chemical equation is as follows.
3 is the coefficient in front of the
The smallest whole-number coefficient is 2.
1.50*10^23 molecules/ (6.02*10^23 molecules/mol)= 0.249 mol.
There is 0.249 mol in 1.50*10^23 molecules~
Hello
We know that polar molecules' attraction is stronger than that of non polar ones; this can be a good basis for us to check the substances' polarity. Knowing that polar forces are stronger, we can eliminate all options referring to them as being the weaker force; that is, options C and A. Next, we know that stronger forces will result in lower volatility so we can eliminate option D. The answer is B, assuming the compound has an odor.
