Which alkali metal is the most reactive on the periodic table?
Hydrogen.
What is the outcome of metal plus water?
The outcome of metal reacting with water can vary depending on the specific metal. Some metals will react with water to produce metal hydroxide and hydrogen gas, while others may not react at all. In some cases, the reaction can be violent and produce a lot of heat and potentially dangerous hydrogen gas.
Explain why hydrogen gas is given off when a reactive metal undergoes a single-displacement reaction with water?
In a single-displacement reaction between a metal and water, the metal displaces hydrogen from water molecules. This results in the formation of metal hydroxide and hydrogen gas as a byproduct. The reactivity of the metal determines the amount of hydrogen gas produced during the reaction.
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.
What is the most reactive metal and nonmetal group in the periodic table?
caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
What is displaced from hydrogen when you add a reactive metal?
When you add a reactive metal, such as sodium or potassium, to hydrogen, the metal displaces the hydrogen gas and forms a metal hydride. This reaction is a displacement reaction where the metal takes the place of hydrogen in the chemical compound.
Is lead reactive or nonreactive?
Lead is a moderately reactive metal. It reacts slowly with air and water, but does not react as vigorously as highly reactive metals like sodium or potassium.
Why is copper not used to prepare hydrogen by the action of dilute HCL on metal?
Copper is not suitable for preparing hydrogen by the action of dilute HCl because it is less reactive than hydrogen. In a displacement reaction, hydrogen will not be displaced from hydrochloric acid by copper due to its lower reactivity. Other metals that are more reactive than hydrogen, such as zinc or magnesium, are typically used instead.
What kind of element is hydrogen?
A reactive non-metal.
Which non metal is the most reactive with hydrogen?
fluorine
Which alkali metal is the most reactive on the periodic table?
Hydrogen.
How reactive is zinc?
Zinc is a moderately reactive metal. It reacts slowly with oxygen in the air to form a protective zinc oxide layer on its surface, which prevents further corrosion. It can react with acids to release hydrogen gas and form zinc salts.
What are the products of the reaction between an acid and a reactive metal?
The products of the reaction between an acid and a reactive metal are salt and hydrogen gas. The metal displaces hydrogen from the acid to form the salt, which is often soluble in water, and hydrogen gas is released as a byproduct of the reaction.
What is the outcome of metal plus water?
The outcome of metal reacting with water can vary depending on the specific metal. Some metals will react with water to produce metal hydroxide and hydrogen gas, while others may not react at all. In some cases, the reaction can be violent and produce a lot of heat and potentially dangerous hydrogen gas.
Is copper a reactive metal?
Yes, copper is considered a moderately reactive metal. It can react with oxygen in the air to form copper oxide, which causes the metal to tarnish and turn green. However, copper's reactivity is lower compared to metals like sodium or potassium.
Is potassium more reactive than hydrogen?
Potassium is more reactive than hydrogen. It is a highly reactive metal that reacts violently with water, while hydrogen is a nonmetal gas that is generally unreactive unless under specific conditions.
What is the reactivity of iodine with other elements?
Iodine is moderately reactive with certain elements. It can react with metals like sodium and potassium to form metal iodides. It can also react with nonmetals like hydrogen to form hydrogen iodide. However, iodine is less reactive compared to elements like chlorine or oxygen.
