Is there a gas form of calcium?
It burns in air or pure oxygen to form the oxide and reacts rapidly with warm water (and more slowly with cold water) to produce hydrogen gas and calcium hydroxide. On heating, calcium reacts with hydrogen, halogens, boron, sulfur, carbon, and phosphorus.
What state of matter can calcium be found in?

What are 3 interesting facts about calcium?
Calcium is nature’s most renowned structural material. Indeed, calcium is a necessary component of all living things and is also abundant in many non-living things, particularly those that help support life, such as soil and water. Teeth, sea shells, bones and cave stalactites are all products of calcium.
What are the source of calcium?
Sources of calcium
- milk, cheese and other dairy foods.
- green leafy vegetables – such as curly kale, okra but not spinach (spinach does contain high levels of calcium but the body cannot digest it all)
- soya drinks with added calcium.
- bread and anything made with fortified flour.
Where is most of the body’s calcium found?
Calcium is the most plentiful mineral found in the human body. The teeth and bones contain the most calcium. Nerve cells, body tissues, blood, and other body fluids contain the rest of the calcium.
What are the negative effects of calcium?
Too much calcium can have negative side effects. Symptoms such as constipation, gas, and bloating may indicate that you’re getting too much calcium. Extra calcium may also increase your risk of kidney stones. In rare cases, too much calcium can cause deposits of calcium in your blood.
What are some unique properties of calcium?
Calcium is a trimorphic type of metal, which is harder than sodium but softer compared with aluminum. Unlike other alkaline metals, calcium is less chemically reactive and doesn’t burn skin. Calcium combines with other elements to form certain compounds that are abundant in the earth’s crust.
What happens if you don’t get enough calcium?
If your body doesn’t get enough calcium and vitamin D to support important functions, it takes calcium from your bones. This is called losing bone mass. Losing bone mass makes the inside of your bones become weak and porous. This puts you at risk for the bone disease osteoporosis.
Which fruit is the rich source of calcium?
A Guide to Calcium-Rich Foods

| Broccoli, fresh, cooked | 1 cup | 60 mg |
| Oranges | 1 whole | 55 mg |
| Seafood | Serving Size | Estimated Calcium* |
Is CaSO4 a solid liquid or gas?
The CaCO3 is solid (s) and you know this because it is insoluble. The CaSO4 is also insoluble, so is (s). The CO2 is, of course, a gas (g) and finally the H2O is liquid (l) at room temperature. Just like HCl is naturally a gas (g) but become acid when placed in water as HCl (aq).
Is CuCl2 a solid liquid or gas?
Calcium Chloride (chemical formula CaCl2) is the ionic compound of calcium and chlorine. It is a salt that behaves as a typical ionic halide, being solid at room temperature and highly soluble in water. Common applications include brine for refrigeration plants, ice and dust control on roads, and desiccation.
Is CaCl2 a solid liquid or gas?
Chemical Information. Calcium Chloride CaCl 2 is an inorganic salt, which exists in a solid form or as a liquid solution. Solid calcium chloride is a white, crystalline substance in the form of flake, granule or powder.
Is caesium a solid liquid or a gas?
Cerium is a grey, shiny or lustrous metal. At room temperature Cerium is a solid. It melts and becomes a liquid at 798 oC and boils and becomes a gas at 3424 oC. It burns in air to form a compound with one cerium atom and two oxygen atoms.
