I've just been reviewing reactions involving metals and have come across a few questions i dont understand
1. Write a balanced equation for the following reactions of metals with dilute acids. If no reaction occurs write "No reaction"
a) Sodium + Cold water
b) Zinc + Steam
c) Platinum + Steam
d) Magnesium + Cold water
When writing the equation I put Cold water as a aqueous solution and the same steam.. But in the answers they have them all as a gas. I understand why steam could be a gas but not why water can be called a gas.
I put c) and d) as no reaction however, the book has put that Magnesium does react with gas. Also, why have they called both water and steam a dilute acid? they did the same in the next question too.
2. Write a balanced equation for the following reactions of metals with dilute acids. If no reaction occurs write "No reaction"
a) Potassium + Oxygen
b) Gold + Oxygen
c) Aluminium + Oxygen
d) Copper + Oxygen
Im not sure if there is something that i am just not getting but if anyone is able to help me out it would be appreciated
