The correct answer to this question is carbon dioxide. A cake rises as it bakes because a chemical change causes carbon dioxide to be produced. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
Answer:
Option 2, 3, and also 6 btw
Explanation:
The other guy was wrong
Answer:
An increase in temperature will result in increase in the average kinetic energy of the reacting particles(atoms). Which will therefore increase the frequency of their collision....
Using collision theory
The reaction rate increases......
Explanation:
As we known that atoms in a liquid substance are closer to each other and they are able to slide past each other because the attractive forces between them are neither too strong or too weak.
Hence, liquid substance are able to take the shape of a vessel in which they are placed. Liquids have a fixed volume but no fixed shape.
On the other hand, atoms of a solid do not have enough kinetic energy. As they are held by strong attractive forces and they only vibrate at their mean position.
Hence, solids have fixed shape and volume.
Thus, we can conclude that in the given situation liquid to solid change of state is taking place.
There is a specific formula to use for these type of problems.
ln (P2/ P1)= Δvap/ R x (1/T1 - 1/T2)
R= 8.314
P1= 92.0 torr
T1= 23 C + 273= 296 K
P2= 351.0 torr
T2= 45.0 C + 273= 318 K
plug the values and solve for the unknown
ln( 351.0/ 92.0)= Δvap/ 8.314 x (1/296 - 1/318)
Δvap= 47630.6 joules
