A very reactive metal can react too violently with acids to be safe.

What is the outcome of metal plus water?
There are many different kinds of metal. There are highly reactive metals such as sodium, which if placed in water will react immediately, forming a sodium hydroxide solution and releasing hydrogen gas. There are moderately reactive metals such as iron, which if placed in water will slowly start to rust. And there are non-reactive (or inert) metals such as gold, which if placed in water don't do anything. Metal + Water (H2O) produces → Metal Hydroxide (OH-) and Hydrogen gas (H2).
Which alkali metal is the most reactive on the periodic table?
Hydrogen.
Name an alkali metal that is more reactive than K Na or Li Name an alkali metal that is less reactive?
Hydrogen (H) is more reactive. Francium (Fr) is less reactive.
Why most of the transition metal not displace hydrogen in acid?
because some metals are less reactive than hydrogen.
Explain why hydrogen gas is given off when a reactive metal undergoes a single-displacement reaction with water?
All reactive metals undergo a similar single-displacement reaction with water. They all form hydrogen.
What is displaced from hydrogen when you add a reactive metal?
Hydrogen is displaced from acid when you add a reactive metal.

What happen when metal is added to water?
it depends what metal it is, if it is a reactive metal like potassium or sodium it will effervesce (bubble) and create a metal hydroxide and hydrogen. if it is a less reactive metal it will create a metal oxide and hydrogen (zinc, etc)
Which non metal is the most reactive with hydrogen?
fluorine
What kind of element is hydrogen?
A reactive non-metal.
Which alkali metal is the most reactive on the periodic table?
Hydrogen.

Hydrogen (H) is more reactive. Francium (Fr) is less reactive.

because some metals are less reactive than hydrogen.
Why does copper give off no hydrogen when reacting in water?
because it isn't a reactive metal
Does zinc reacts with the acid?
Yes it does. It is a reactive metal and displaces hydrogen from the acids to give a zinc salt and hydrogen gas.
Explain why hydrogen gas is given off when a reactive metal undergoes a single-displacement reaction with water?
All reactive metals undergo a similar single-displacement reaction with water. They all form hydrogen.
Show experiment for metal and hydrochloric acid?
Acid + Reactive Metal -----> Salt + Hydrogen Gas e.g. 2HCl + Zn --------> ZnCl2 + H2
