Answer : The enthalpy change for the reaction is, 97.7 kJ
Explanation :
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
The given main chemical reaction is,

The intermediate balanced chemical reaction will be,
(1)

(2)

(3)

Now we are multiplying reaction 1 by 2 and reversing reaction 3 and then adding all the equations, we get :
(1)

(2)

(3)

The expression for enthalpy of main reaction will be,



Therefore, the enthalpy change for the reaction is, 97.7 kJ
Pretty sure it's 6 the atomic mass
Explanation:
What would a biologist see if she examined a small piece of a leaf from a plant and a small piece of a root from the same plant through a microscope? Both the leaf and the root would be made up of cells. The leaf would be made up of cells, but the root would not be made up of cells.
Answer:
The stronger acid is HBrO3.
Explanation:
It has an additional oxygen making it more electronegative, in turn making it a stronger acid.
Answer:
They explode!!!
Explanation:
When atoms separate they release all the energy and particles in themselves and cause a chain reaction to all other atoms causing an explosion
Hope this helps, and have a nice day!
