Metals and Non-metals
Metals like aluminium, iron and zinc do not react either with cold or hot water but they react with steam to form metal oxide and hydrogen (g) 2Al + 3H2O → Al2O3 + 3H2 3Fe + 4H2O → Fe3O4 + 4H2 Metals like gold, silver, and copper do not react with water at all
The General Reaction Of An Acid With A Metal Carbonate …
The calcium carbonate will not actually dissolve well in water, but it should be possible to determine that the solution is basic, from the tiny amount of calcium carbonate that will dissolve when the chalk dust is suspended in water.

What does calcium NOT react with? | Yahoo Answers
2008/2/18· most likely Ca will not react with other metals because the elements like to have balance so if Ca has a +2 charge and Al has a +3 charge it will require a lot of energy to get these to react however if an element has a -2 charge Ca will be very reactive on most cases because it get balance +2 + -2 =0 which is what it wants however element can be forced to react with each other so it will

Reaction of calcium with water Calcium reacts slowly with water. This is in contrast with magnesium, immediately above calcium in the periodic table, which is virtually unreactive with cold water. The reaction forms calcium hydroxide, Ca(OH) 2 and hydrogen gas
Calcium - Simple English Wikipedia, the free encyclopedia
It reacts with water to produce hydrogen and calcium hydroxide.It reacts with water very fast when it is powdered. When it is in a chunk, it starts reacting slowly because calcium hydroxide makes a coating that does not dissolve on the calcium. If a little acid is added to calcium hydroxide, it dissolves it, making the calcium react very fast.
Water and Metals - Evolving Sciences
Remeer not all metals are the same. While there are a lot of metals which don’t react with water, there are still quite a few which do. Calcium is a metal, which when placed in water, reacts violently. This is seen in the video to the right.
