What else can I help you with?
What metal plus base?
When a metal reacts with a base, it can form a salt and hydrogen gas. The metal hydroxide is typically formed when a metal reacts with a base, such as sodium hydroxide or potassium hydroxide. The metal hydroxide is soluble in water and will produce a basic solution.
Which gas is given out when sodium hydroxide reacts with a metal?
Hydrogen gas is given off when sodium hydroxide reacts with a metal. This is due to the displacement reaction that occurs where the more reactive metal displaces hydrogen from water molecules in the sodium hydroxide solution.
What happens when a metal oxide reacts with water?
When a metal oxide reacts with water, it forms a metal hydroxide. This is a chemical reaction where the metal oxide molecule combines with water molecules to produce a new compound. The reaction typically generates heat and produces hydroxide ions in the solution.
How do these show if a metal reacts with the acid?
If a metal reacts with an acid, you will observe bubbles of gas being produced, a change in temperature (either an increase or decrease), and the metal may appear to dissolve or form a metal salt in the solution. These are common indicators that a chemical reaction is taking place between the metal and the acid.
Which metal will react spontaneously with Cu2 (aq) at 25C?
Zinc (Zn) will react spontaneously with Cu2+ ions in aqueous solution at 25°C, since it has a higher potential for oxidation compared to copper. This reaction will result in the displacement of copper from the solution by zinc as zinc's oxidation potential is higher.
Which non-metal will ignite spontaneously if it is exposed to oxygen?
When a non metal reacts with oxygen it produces acidic or neutral oxides
When an acid reacts with a metal the liquid changes colour to green?
This depends on the metal; nickel chloride solution is green.

Hydrogen gas is given off when sodium hydroxide reacts with a metal. This is due to the displacement reaction that occurs where the more reactive metal displaces hydrogen from water molecules in the sodium hydroxide solution.
When a metal reacts with water what products are made?
When a metal reacts with water, it can produce metal hydroxide and hydrogen gas. The metal hydroxide is a basic compound that dissolves in water to form a basic solution, while the hydrogen gas is released as a byproduct of the reaction.
What happens when a metal oxide reacts with water?
When a metal oxide reacts with water, it forms a metal hydroxide. This is a chemical reaction where the metal oxide molecule combines with water molecules to produce a new compound. The reaction typically generates heat and produces hydroxide ions in the solution.
Which gas is produced when a metal reacts with a dilute acid?
Hydrogen gas is produced when a metal reacts with a dilute acid. This reaction occurs when the metal displaces hydrogen from the acid, forming metal salts and releasing hydrogen gas as a byproduct.

What are the chemical properties of Europium?
Europium is the most active of the lanthanides. it reacts quickly with water to give off hydrogen. it also reacts strongly with oxygen in the air, catching fire spontaneously. Scientists must use great care in handling the metal.
What substance reacts with water to give a solution of pH value greater than 7?
For example an alkali metal.
What is formed when a metal oxide react with water?
When a metal oxide reacts with water, it forms a metal hydroxide. This reaction typically involves the metal oxide releasing hydroxide ions when it reacts with water molecules. Metal hydroxides are basic compounds that can dissociate in water to form metal cations and hydroxide anions.
