6 0

Answer:

Explanation:

A catalyst is a substance that increases the rate of a chemical reaction without itself getting consumed in the reaction as it helps in decreasing the activation energy. Thus, rate of reaction also increases.

A positive catalyst helps in increasing the rate of a chemical reaction whereas a negative catalyst decreases the rate of a chemical reaction.

Whereas when we increase the temperature then collisions between the particles increases due to increase in kinetic energy. Hence, rate of reaction increases with increase in temperature.

Thus, we can conclude that out of the given options adding a positive catalyst  will increase the rate of a chemical reaction.

sertanlavr [38]

Answer:

Oh gosh, I had to listen to an audio recording of me doing a speech for my English class to make sure I got it all so this is the perfect time for me to answer this!

What I liked about that way I presented myself is that I was actually able to get all my points across, and in the right order, without going away from the script to much.

What I didn't like for one was my voice (lol) so if I could rerecord that but have someone else speaking for me who sounds more confident and less like me that would be great. Another thing I didn't like was that I sounded nervous, so my points didn't come across as well as they did on paper.

Improvements I would make is actually practicing before diving headfirst into recording, so I can hopefully make they come across stronger. I would also ahead of time research a bit more than I did, and add more facts to the actual debate.

I hope this is a good answer to your questions><

Story " A Modern Love Letter" How does the author of " A Modern Love Letter" create surprise? Cite examples of how the author's
Luba_88 [7]

Answer:

The author makes sudden actions of Bella that would create surprise and also be at suspense for the reader at the same time. The way people call Bella in a letter surprises her because it makes her special to someone. “I bend to retrieve it, surprised to see “My Bella” scrawled ornately across the front.” The author foreshadows to create a flashback of what happened earlier in the short story.

When the author states in the story “I look past him, but Abuela gasps and exclaims, “Alejandro, after all these years!” the author creates surprise and a feeling of the story's climax. When the author uses foreshadowing he makes the main character show emotion and express herself throughout the short story. Small actions like when Bella recognized who is writing to, make her think or foreshadow the past and then she gets surprised as she notices who is likely writing to her.
