    Based on my print example, are the deltaH equations treated separately, or treat it with no space before the delta? Thank you.

    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.

    ΔHvap = m(2259 J/g)
    ΔHfus = m(334 J/g)

     

    Thanks!

    Good day and thank you for your question, Cheryl.

    What you entered in your question I would braille as follows:

    ⠨⠠⠙⠠⠓⠧⠁⠏⠀⠨⠅⠀⠍⠷⠆⠆⠢⠔⠀⠰⠠⠚⠸⠌⠰⠛⠾

    ⠨⠠⠙⠠⠓⠋⠥⠎⠀⠨⠅⠀⠍⠷⠒⠒⠲⠀⠰⠠⠚⠸⠌⠰⠛⠾

     

    You said you have examples where  ⠸⠙⠠⠓  and  ⠨⠠⠓  are used for ΔH (“Delta H”). I do not know why that is.

    The document attached in two file formats shows common print presentations of your examples and their corresponding transcriptions in simbraille.

    I hope this is helpful.
