What else can I help you with?
Is calcium safe to touch?
The calcium could react with the moisture on your skin, and calcium reacts with water by releasing hydrogen,I think it also boils, also, if you look on youtube for a video, you can see what calcium does to the water.
What is ther reaction between dissolving limestone chips in hydrochloric acid?
Limestone is a compound known chemically as calcium carbonate. It reacts with hydrochloric acid to form calcium chloride, carbon dioxide gas and water. The carbon dioxide is responsible for the fizzing you see in the reaction. The reaction is as follows: CaCO3 + 2HCl --> CaCl2 + CO2 + H2O
What is the Equation for when carbonate reacts with acid?
A reaction between an acid and a carbonate gives a salt, water and carbon dioxide. So the word equation is: acid + carbonate -----> salt + carbon dioxide + water eg: hydrochloric acid + calcium carbonate ----> calcium chloride + carbon dioxide + water See: http://www.sky-web.net/science/reaction-types.htm
What happens when magnesium oxide is put in hydrochloric acid?
When magnesium oxide is put in hydrochloric acid, it will react to form magnesium chloride and water. The chemical reaction can be represented as: MgO + 2HCl -> MgCl2 + H2O. This reaction is a classic example of an acid-base reaction where the base (MgO) reacts with the acid (HCl) to form a salt (MgCl2) and water.
Is the reaction between Sulfuric acid and Calcium carbonate an example of neutralisation?
H2SO4 + CaCO3 --> CaSO4 + H2O + CO2It is balancedGenerally, when you see a carbonate group in the reactants part of a reaction, the products will contain CO2 in it.--------------------------------------…ADDITIONAL REQUESTED DETAILS--------------------------------------…CaCO3 is highly insoluble in water and will not usually dissolve in any significant amount in water unless CO2 is present and dissolved in the water. I don't think your reaction will actually proceed.This is the only possible reaction and it is highly unlikely to happen at all, infact the reverse reaction is much more favored.CaCO3(s) + H2O(l) → Ca(OH)2(s) + CO2(g)This is what we call acid rain.
What would you see when water is added drop by drop to cold calcium oxide?
When water is added drop by drop to cold calcium oxide (CaO), a vigorous exothermic reaction occurs, producing calcium hydroxide (Ca(OH)₂) and releasing heat. Initially, you might see the calcium oxide fuming or bubbling as it reacts with water, creating a slaked lime paste. The reaction can produce steam, and the temperature of the mixture will increase significantly due to the heat generated. Eventually, you would observe a thick, milky solution of calcium hydroxide forming.
What is the name of the binary compound that has the formula CaO?
CaO is the chemical formula of calcium oxide.
What happend when you mix carbon dioxide with lime water?
Lime water reacts with carbon dioxide to produce a precipitate of calcium carbonate (CaCO3): Ca(OH)2 (aq) + CO2 (g) → CaCO3 (s) + H2O (l) As you can see, it also produces water (H20). Thus, lime water can be used to detect the presence of carbon dioxide.

Why the lime water turn cloudy?
CO2 (Carbon Dioxide). Carbon dioxide in the gas you put the limewter near reacts with calcium hydroxde to form white particle solids of calcium carbonate which is sparing soluble. you see these particles as a suspension, much like milk
What happens when copper oxide reacts with dilute sulpuric acid?
Let's see! CuO + H2SO4 --> CuSO4 + H2O ======================== This reaction is what I think would theoretically happen here; a salt, copper sulfate, and water produced.
Small pieces of calcium are added to a beaker of cold water why do the calcium pieces move up and down?
Calcium oxidizes when combined with water. If you were to pour calcium powder into a beaker of water, you would see a much more dramatic effect, as the increased surface area of the powder catalyses the reaction. Also, calcium pellets (resembling gravel) react similarly with water, oxidizing and bubbling, and raising the temperature of the water. Your calcium samples must have been small enough to float to the surface on the gaseous bubbles created during the oxidation, and sank to the bottom once again after the bubbles were released.

Does citric acid dissolve calcium carbonate?
Yes, citric acid can dissolve calcium carbonate. When citric acid comes in contact with calcium carbonate, it reacts to form calcium citrate and carbon dioxide gas, thereby dissolving the calcium carbonate.

How do we know that sodium reacts with water just by looking?
because when it combined with water you will see it boiling
The method for making an exothermic reaction?
Exothermic reaction of calcium oxide 1AimTo see how the mass of calcium oxide affects the temperature change produced in a reaction with waterTheoryAdding Calcium Oxide to water produces an exothermic reaction as aqueous Calcium Hydroxide is formed. The total energy released will increase as more bonds are broken by using a greater mass of Calcium HydroxideEquipmentCaO powderDe-ionised water50 ml measuring cylinderInsulating beakerBalance (.01g resolution)Temperature probe and data loggerStirring rodMethodIn an insulating beaker combine 50ml of water with 1g of CaOStir and record the maximum temperature reached using a temperature probe and dataloggerRepeat the experiment by using fresh water and increasing the mass of CaO used by 1gSafetyAs CaO will react exothermically with water care should be taken to avoid contact with skin where reaction with moisture could cause irritation and in extreme cases burns.
