A. release the acid into the lye more slowly
This will allow for a more controlled reaction between the acid and lye, preventing it from becoming too hot too quickly. It will also help regulate the cooling off process, resulting in a more stable temperature for the device.
Ava made a device that contains two chemicals: lye and a strong acid. When she activates the device, the acid is added to the lye. When these two chemicals mix, they react and produce heat.
When Ava tests the device, she finds that it becomes far too hot but then cools off too quickly. How should Ava change the device to fix these problems?
A.
release the acid into the lye more slowly
B.
cover the device with a substance that conducts heat
C.
increase the amount of acid added to the lye
D.
