    Re: Chemistry heat

    Why did you write the problem two times?

    Q=mcΔt

    Q mΔt=c
    This last equation obviously should be c = Q / (m Δt).

    C = 2.09 joules
    g c
    The answer is correct, but please write expressions in one line and use parentheses to change the order of operations, e.g., C = 2.09 J / (g C).
