Reactions ?
does calcium, copper, iron, magnesium or sodium not react with water and acids?
does calcium, copper, iron, magnesium or sodium react with acids and react with water slower?
does calcium, copper, iron, magnesium or sodium react quickly with acid and acids?
does calcium, copper, iron, magnesium or sodium react steadily with acids?
Which one for which?
I'm stuck!
Answers:
The reactivity increases as you go from copper to iron, magnesium and sodium.
Copper does not react with water (or steam) and only reacts with fairly concentrated acids. (especially oxidising acids like nitric)
Iron will only react with steam if the iron is heated strongly and reacts quite slowly with dilute mineral acids. (e.g. hydrochloric acid) (To cause iron to rust other chemicals are needed in addition to water)
Magnesium reacts very slowly with water but quite rapidly with steam. It reacts rapidly with dilute acids.
Calcium reacts quickly with cold water and quite violently with dilute acids
Sodium reacts vigorously with cold water, violently with hot water and is too dangerous to add to dilute acids.
Use your text book and do your own homework. You'll learn much more that way. (Sorry, I know you'll hate that answer right now. But if you want to get anywhere in life you have to do some of your own work sometime.)
If you can't make heads or tails of your textbook, you might learn something from finding a examples by lookign through search engine results.
Didn't the professor show you a reaction or two in class? Magnesium is REALLY IMPRESSIVE by the way.
You might look for something called "the Reactivity Series."
1)Na
2)Cu
3)Fe
4)quickly but not explosively:Ca
5)Mg
these would be my answers, but a couple of the questions are ambiguious, i've answered useing each element just once, which is probably what they want.
don't mix any type of metal with an acid. as far as sodium goes if you come across some, no water, it will explode
as far as any type of metal, don't mix with acids. sodium will explode with contact with water. Magnesium will react with HCL acid and produce hydrogen gas.bad stuff if your around a fire or static electricicity. You did not mention Lithium in it's solid form, it can burst into flames at humidity levels of 70% . don't do a science project on anything that you are not sure about your hyothesis. calcium, copper, and iron are slow in reaction with acids. In general don't mix acids with bases..vinegar and baking soda are safe but don't mix them in a sealed container. Be safe!

all these metals react with acids - HCl, H2SO4 & HNO3. to give various salts, sodum will however react with an explosion even in water.
