What else can I help you with?
Is calcium metal more or less dense than water?
Calcium metal is more dense than water. If you had a block of calcium and dropped it in a container of water, it would sink. Note! Calcium reacts with water! Calcium metal is stored in a container beneath kerosene or another liquid to isolate the metal from air. Calcium will chemically react with the moisture in air and will thus be decomposed.
What happens when you touch calcium metal?
Sensory nerves in your finger trigger minute electrical impulses which travel to your brain. Your brain then interprets those impulses as one thing or another and you say, "Hmm, that's what calcium metal feels like."
Why is there a white coating on calcium?
The white coating on calcium is likely calcium carbonate, which forms when calcium comes into contact with carbon dioxide in the air. This reaction creates a thin layer of calcium carbonate on the surface of the calcium, giving it a white appearance.
What gas is formed when sulfur burns?
When sulfur burns, sulfur dioxide gas (SO2) is formed. This gas is known for its pungent odor and is a common air pollutant.
Gas formed when sulfur burns in air?
When sulfur burns in air, it forms sulfur dioxide gas (SO2). Sulfur dioxide is a colorless gas with a pungent smell and is a major air pollutant. It can react with moisture in the air to form sulfuric acid, contributing to acid rain.
What metal burns in air but only reacts slowly in water?
It depends what you mean by slowly! Calcium burns in air and reacts fairly quietly with water, certainly much more slowly than the alkali metals do.
What is the product formed when Oxygen burns in air?
Oxygen can not burn in air.
What is the chemical that is formed when hydrogen burns in air?
Water.
What metal burns with a silver flame in air?
magnesium
When a metal burns the metal combines with oxygen from the air to form a chemical called a what?
oxide.

When magnesium burns in air in addition to the oxide being formed what other product will be formed?
water
What is the poisonous gas formed when methane burns in a limited supply of air?
Carbon monoxide is the poisonous gas formed when methane burns in a limited supply of air.
When calcium is exposed to air what happens?
When calcium is exposed to air, it reacts with the oxygen in the air to form calcium oxide. This reaction produces a layer of white calcium oxide on the surface of the calcium metal, which is commonly known as calcium oxide or quicklime. This layer of calcium oxide can help protect the underlying calcium from further oxidation.
What compounds are formed when nicotine burns in air?
carbon dioxide water
When a metal burns does it combine with oxygen from the air?
yes it does and it forms an oxide.
What is the product formed when calcium hydroxide reacts with air?
When calcium hydroxide reacts with air, it forms calcium carbonate. This is due to the absorption of carbon dioxide from the air, leading to the formation of a white precipitate.
