Which is more basic calcium carbonate or calcium oxide?
Calcium oxide is a compound of calcium and oxygen and has the formula CaO. It is very basic (alkaline) and will react with water to form calcium hydroxide, Ca(OH)2 which is a strong base. Calcium oxide is commonly called lime or quicklime.Calcium carbonate is a compound of calcium, carbon, and oxygen with the formula CaCO3. It is mildly basic and will not react with water nor is it water soluble. It is commonly called calcite, limestone, or marble.
Name the alkali metals?
List of Alkali: Lithium hydroxide Sodium hydroxide Potassium hydroxide Rubidium hydroxide Caesium hydroxide Francium hydroxide Strontium hydroxide Barium hydroxide Ammonium hydroxide Calcium hydroxide Magnesium hydroxide
Your skeleton stores calcium. How does calcium get into your body?
The right way
How are the salts named?
Salts made of a metal and a nonmetal are named this way: [metal] [nonmetal root]-ide Examples: sodium + chlorine = sodium chloride potassium + iodine = potassium iodide Salts made from a metal or other complex cation and a nonmetal or other complex anion are named based on the cation and anion names: ------------------------------- ammonium ion + hydroxide ion = ammonium hydroxide sodium ion + hypochlorite ion = sodium hypochlorite calcium ion + chloride ion = calcium chloride
How does calcium enter your body?
You ingest calcium in the food you eat and the milk you drink.
Is calcium hydroxide safe to consume?
It is unsafe to drink because and any hydroxide is created by hydrochloric acid, Calcium Hydroxide is therefore unsafe to drink. However the dilute solution of Calcium Hydroxide is Limewater, which is not recommended to drink because it is the main way to test for Carbon Dioxide. It can make you feel sick and cause painful vomiting, but other than that has no other affect on the human body.
Why can calcium hydroxide be used to test for carbon dioxide?
I have just answered this question as part of homework myself, limewater is a common name for Ca(OH)2 (calcium hydroxide) and when limewater and carbon dioxide meet they instantly react in a visible way. The limewater turns cloudy, sort of like when milk and water meet. Hope this helps

Why is magnesium hydroxide used as an antacid instead of sodium hydroxide?
Sodium Hydroxide is way too basic (very high pH) and would cause internal damage.
Is calcium hydroxide like carbon dioxide?
Well ... they're both chemical compounds ... Other than that, no; they're different in just about every possible way.
What gas is produced when calcium metal is dropped in water?
HYdrogen. The Group (II) Alkaline Earth elements, of which calcium is one, react in a similar way the Group (I) Alkali metals, but less vigorously. So like sodium and water produces sodium hydroxide and hydrogen . # Then calcium and water produce calcium hydroxide and hydrogen. Here is the reaction eq'n. Ca(s) + 2H2O(l) = Ca(OH)2(aq) + H2(g) .
Sulphuric Acid plus Calcium Hydroxide equals?
Calcium Sulphate and water. The easy way to see this is that you have an acid reacting with an alkali (hydroxides are always alkalis), so the reaction is a neutralisation reaction, meaning that it produces water. This leaves a sulphate ion and a calcium ion, which react to form the salt calcium sulphate.
Is calcium nitrate plus ammonium hydroxide a physical change?
No, it is a chemical change. Rearrangement of atoms to make different compounds is one way to define a chemical reaction.
Why is a chemical reaction created between calcium and water?
Calcium is not found as the metal in nature. It prefers to be a compound. Nature abhors energy and always tries to minimize it. That is why iron and steel rust. Nature prefers iron to be lower energy- rust. In the same way, calcium is far lower energy and far more stable as calcium hydroxide than calcium metal. So calcium reacts with water because it is so energetically favorable. Ca + 2H2O -------> Ca(OH)2 + H2
How is calcium used in muscle contraction?
Calcium binds to troponin, which moves the tropomyosin out of the way so that myosin can bind to actin; this ultimately causes a power-stroke.
