I see others have asked the same question but I do not understand the answers given. Question is to do with zinc solid and dilute sulphuric acid. What substance is left?
I see by other posts that Bob Pursley answered this question. I haven't seen his answer but here is a hint.
Zn(s) + H2SO4(aq) ==> ZnSO4(s) + H2(g)
s = solid
aq = aqueous solution
g = gas
bob pursley didn't give mea or monty the answer he just copied what mea had said. The actual question was what substance is left after putting solid zinc and dilute suphuric acid together, apart from zinc sulphate. Can you put it not in a formula, i haven't done formulas yet?
Is it steam?
The legend I supplied with the formulas tells you everything you want to know.
s is solid, aq is for aqueous solution and g is for gas. The left side of an equation is what you put together. The right side is what you get out of the reaction. So what do you think is left? Zn is zinc. H2SO4 is sulfuric acid. ZnSO4 is zinc sulfate. H2 is hydrogen. I hope this helps.
that's what i needed to know thanks
hello haw are you doing today can you tell me what weather fronte means as soon sa posable
what does weather fronte mean
A weather front is a mass of air, cold for a cold front and warm for a warm front, that moves across a wide area of the earth. They are drawn on the map as ) or (. Here is a site that may explain it a little better.
How do we do the calculations when titrating 99% of 0.1molar of sodium hydroxide and 99% of 0.1molar of sulphuric acid in a 1 litre? Please can l have the answer as soon as possible.
