Given that I no not see any explanation in the previos answer, I think you can benefit of this.
Exothermic refers only to the fact that the reaction releases energy in the form of heat when occurs. So, the enthalpy is higher at start and lower and the end.
Seen in this way, you can deduct that the change in enthalpy is negative, which is what the third option says.
Answer:
1a) Obtuse
1b) Alternate inner angles
1c) x = 101 degrees
2a) Obtuse
2b) Alternate outer angles
2c) x = 147 degrees
Step-by-step explanation:
I hoped these helped. If possible, may I have brainliest :)
Answer:
A must be true
Step-by-step explanation:
Since ABE and angle ACE are right angles the rest of the 2 angles are right angles either therefore EC = AB
Answer:
yes
Step-by-step explanation:
No because y=5 is a horizontal line on a graph, in this scenario the x-values would stay the same
