Hey, cheers spending some time on this :p
I feel like I failed to properly elaborate what my problem with the question was, because I do have the basics down, but the question itself was defined so vaguely, probably on purpose, that I just need some help on clearing out the fog...
And that's to say, with which reagents am I working here? I mean, is my equation truly just:
"Cr + H+"? That can't be right, can it? I'm sure there's more going on, that's not explicitly written. :s It's implied that there is water involved in a follow-up question, but it's not explicit.
EDIT: A friend of mine noted that "water can't be part of the equation, metals and acid produce "salt" and hydrogen gas. The 'water' can only be the source of the acid. I assume you need to add an equation of the water's-breakdown to H3O+ and OH-"
I am translating from another language, so the terms are most likely incorrect, sorry about that. <:
Any thoughts on how this might lead me to the initial equation, to this incredibly vague question?
