Will you have to show me what you're talking
<span>Yes its H2O , the H2O and the OH- are acid/Base Conjugate pair................just like NH3 and NH4

A scientist would most likely need to update her model when it no longer supports the latest results.
The ionic compound is CaSO4
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
