What is the balanced symbol equation and the physical state of calcium oxide plus hydrochlroric acid-- calcium chloride plus water?
CaO(aq) + 2HCl(aq) -> CaCl2(aq) + H2O(l) An ionic bonded and dissociated compound, calcium oxide, reaction with a fully dissociated strong acid, hydrochloric acid that produces a dissociated salt, calcium chloride and water.
What is the state of matter calcium hydride is in?
Calcium Hydride is a solid.
What is hydrogen oxide in its solid state?
Ice.
What physical state is sodium oxide at room temperature?
Sodium oxide is a soft solid at room temperature.
What is the electron configuration of calcium in its excited state?
The electron configuration of calcium is [Ar]4s2.
What is the oxidation state of Calcium-?
The oxidation states of calcium are +2, +1. It is considered to be a strongly basic oxide.
Why can't calcium carbonate exist in a liquid state nor in the gaseous state?
At high temperature calcium carbonate (CaCO3) is decomposed in calcium oxide (CaO) and carbon dioxide (CO2).
What is the chemical formula acid?
AnswerLimestone is largely composed of calcium carbonate, also known as CaCO3.This can become quicklime (Calcium Oxide) and carbon dioxide from high levels of heat. This can be shown as:Calcium Carbonate = Calcium Oxide + Carbon Dioxide.CaCO3 = CaO + CO2Quicklime can become slaked lime (solid state) or limewater (aqueous state) or calcium hydroxide from adding water. This produces heat in an exothermic reaction.Calcium hydroxide = Calcium Oxide + WaterCaOH2 = CaO + H2
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.
When calcium oxide changing to calcium hydroxide is a chemical?
Anytime you have a reaction that changes the state of the matter, such as the change from calcium oxide to calcium hydroxide, it is a chemical reaction. Ex. CaO+H2 reacts to form CaOH you then must balance the charges by putting a 2 in front of CaO and CaOH 2CaOH + H2 reacts to form 2CaOH
What is the balanced symbol equation and the physical state of calcium oxide plus hydrochlroric acid-- calcium chloride plus water?
CaO(aq) + 2HCl(aq) -> CaCl2(aq) + H2O(l) An ionic bonded and dissociated compound, calcium oxide, reaction with a fully dissociated strong acid, hydrochloric acid that produces a dissociated salt, calcium chloride and water.
What Is The Chemical State of a Marble?
The chemical name of marble is calcium carbonate formed by the reaction of calcium oxide with carbon dioxide... CaO + CO2 --> CaCO3 I hope this would help u...........
What state is mercuric oxide in?
Mercuric oxide is in the solid state.
What is the final oxidation state of calcium after reaction?
The final oxidation state of calcium after a reaction depends on the specific reaction and compounds involved. Calcium commonly forms a +2 oxidation state by losing two electrons. However, it can also form other oxidation states, such as +1 in certain compounds or complexes. To determine the final oxidation state after a reaction, one must consider the rules of oxidation states and analyze the compound formed.
What is quick lime used for?
Quicklime (Calcium Oxide) is an efficient scavenger of moisture in its dehydrated state. A material that is mostly calcium oxide (CaO) in natural association with a lesser amount of magnesium oxide. Quicklime is capable of combining with water to form hydrated lime.
How can you tell difference between calcium oxide and calcium carbonate?
There are several tests, ranging from a product test (react the sample with acid and then find out what is produced) to a phase test (heat a sample to the midpoint of the melting points of the "suspects" and observe its state).
What is the state symbol for calcium oxide?
symbol of calcium is Ca
