Your instances of “Delta H equals something” are separate equations. Each should be preceded by a space to separate them from the chemical reaction. (Delta H etc. is an expression of the change that happened in the preceding reaction.)
Can you provide a sum braille sample of the following thermochemistry example. We have two different braille books that show the delta H differently (456, 145, 6, 125 or 46, 6, 125), the first way is notated as enthalpy.
