The chemical make-up changes.
Answer:
In the conservation of mass, mass (which is the same as energy) can never be created or destroyed in the same way oil is formed from the remains of small animals and plants that died and fell to the bottom of the sea and their mass (energy) is conserved as oil.
I would say 44 bc divide and add in the slot will give u the answer
I assume you mean diato
mic elements.
Those are hydrogen, oxygen, nitrogen, fluorine, chlorine, bromine, and iodine. They all exist in the form

(

). Where they are all bonded to another one of themselves (a hydrogen atom binds to another hydrogen atom, a fluorine atom binds to another fluorine atom, etc.)
Answer: c. ΔH˚ is positive and ΔS˚ is positive
Explanation:
According to Gibb's equation:

= Gibbs free energy
= enthalpy change
= entropy change
T = temperature in Kelvin
= +ve, reaction is non spontaneous
= -ve, reaction is spontaneous
= 0, reaction is in equilibrium
Thus for 
Case :
> 
when
both have positive values.


Reaction is spontaneous only at at high temperatures.
