Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction.
Q. Is 2Mg O2 2MgO exothermic?
2Mg+O2–> 2MgO + Heat. This is an exothermic reaction.

Q. Is mg o2 -> 2mgo balanced?
Now, there are equal amounts of magnesium atoms and oxygen atoms on both sides, and so the equation is balanced.
Q. What type of reaction is CuCO3?
decomposition reaction
Q. Did Pb2+ react with KI?
Yes, Pb2+ react with KI. KI is a compound. It is a combination of potassium (K) and iodine (I).
Q. What is the Colour of CuCO3?
green
Q. What is the product of CuCO3?
[Note: Shipped as a liquefied compressed gas. Solid form is utilized as dry ice.]…Search by products (CuO, CO 2)
| 1 2 | |
|---|---|
| 1 | CuCO3 → CO2 + CuO |
| 2 | (CuOH)2CO3 → H2O + CO2 + CuO |
| 3 | O2 + CaCO3 + Cu2S → CO2 + CuO + CaSO3 |
| 4 | O2 + CaCO3 + Cu2S → CO2 + CuO + CaSO4 |
Q. Why is CuCO3 green?
Copper carbonate always stays as copper carbonate hydroxide in the atmosphere. The copper powder reacts with oxygen, forming an opaque coating of copper oxide that tends to be green or bluish-grey in color. Hence, the colour of copper carbonate is green. So, the correct answer is option B.
Q. Is CuCO3 a base?
Copper Carbonate is a very weak base. CuCO3 does not exist. What is commonly called copper carbonate is Cu(OH)2.
Q. What is CuCO3 CuO CO2?
Cupric Carbonate = Tenorite + Carbon Dioxide.
Q. What type of reaction is so3 CaO → caso4?
CaO + SO 3 → CaSO. 4 This is an acid-base reaction (neutralization): CaO is a base, SO 3 is an acid.
Q. Is 2kclo3 2kcl 3o2 a redox reaction?
Answer. Explanation: KClO3 is a decomposition reaction. As there is change in oxidation number, so it is a redox reaction where oxidation and reduction takes place.
Q. What type of reaction is Ca OH 2 CO2 CaCO3 H2O?
Insoluble milky white precipitate of calcium carbonate and water is produced when calcium hydroxide reacts with carbon dioxide gas. The reaction follows a double displacement reaction.
Q. Is Ca Oh 2 CO2 an acid base reaction?
This is an acid-base reaction (neutralization): Ca(OH) 2 is a base, CO 2 is an acid. [Note: Readily absorbs CO2 from the air to form calcium carbonate.]
Q. Why does Limewater turn milky?
Carbon dioxide reacts with calcium hydroxide solution to produce a white precipitate of calcium carbonate. Limewater is a solution of calcium hydroxide. If carbon dioxide is bubbled through limewater, the limewater turns milky or cloudy white.
