Answer:
The correct option is c) exothermic, negative.
Explanation:
Reactions that releases heat to the surroundings are called exothermic, and are characterized by negative entalpy (ΔH) values.
Answer:
The correct option is C
Explanation:
From the question we are told that
The reaction is
Generally
Here is the change in enthalpy
is the change in the internal energy
is the difference between that number of moles of product and the number of moles of reactant
Looking at the reaction we can discover that the elements that was consumed and the element that was formed is and and this are both gases so the change would occur in the number of moles
So
The negative sign in the equation tell us that the enthalpy would be less than the Internal energy
A) Burning
Burning is a chemical reaction while the other three answers are physical reactions.
.......,ok first,WHAT THE WORLD THIS THAT!? And this may be how bread formed
Is it 8.06?
Or 58.57?
Don't get mad if there wrong!!
But please let me know if it's right or wrong tho.
