hello everyone before you all start getting angry, i am a bit slow. To write my notes out my teacher is very agresive and angry.

Please can you tell what happens when you mix zinc and hydrochloric acid i saw the experiment, but could not write it down in time.

Thank you

2nd
What happens or is the result when iron and hydrochloric acid is mixed, once again i saw the experiment but could not get it written down because i am a litlle slow. I
Get a 90 per cent of my questions right when i do them in my own time:the education system in england does not allow for this sorry folks:

Any help would be great thanks

This is a 'reactivity' experiment. These kind of experiments are usually to determine whether a metal is reactive or not.

But here's the reaction anyhow:

Zn + 2HCl = ZnCl2 + H2

Any metal plus an acid = a metal salt (halides for HCL and sulphates for H2SO4) and hydriogen gas. Hydrogen gas is diatomic and always H2, so make sure you have the equation balanced.

ITS
zinc + hydrochloric acid = hydrogen + zinc chloride
AND
iron + hydrochloric acid = hydrogen + iron chloride

This is from 2007 - I would guess OP has his answer. I have requested that your other thread be removed. You have too much time on your hands.

Well, since this thread was revived... it means that there might still be more people looking at it.

The above statement I quoted is wrong. Usually, the reaction of a metal and an acid is for the production of hydrogen gas in the laboratory.

When Zinc is mixed with Hcl they react which cause a gas called Hydrgon to be realased. When you light a stick and places it in the gas a loud pop goes off. The flame which reacts with the HCl and Zinc from the test tube.

Zn(s) + HCl (aq)----> ZnCl2(aq) + H2(g)

[JudyKayTee]

Zn(s) + HCl (aq)----> ZnCl2(aq) + H2(g)

This is from March 2007 - please keep an eye on the dates when you answer.
