What else can I help you with?
What happen when borax is heated strongly?
When heated borax undergoes various transitions,first it loses water molecules and swells,then it turns into a transparent liquid solidifying to for a glass like structure called borax beads. Na2B4O7.10H20 -->heating Na2B4O7 -->heating 2NaBO2 + B2O3 BORAX SODIUM BORIC METABORATE ANHYDRIDE
What is the chemical equation of CaCO3 heated to form CaO and CO2?
It depends on the reaction temperature. At 298K, the heat of reaction is 179 kJ/mol
What is the chemical formula of quicklime?
The Chemical formula for lime is CaO. This comes from Limestone (CaCO3). As Limestone is heated up to 1000 degrees, it lets of Carbon Dioxide and becomes CaO, or quicklime.
What gas is produced when CaCO3 is heated?
When CaCO3 (calcium carbonate) is heated, it decomposes to form CaO (calcium oxide) and CO2 (carbon dioxide) gas is released.
When marble is heated what is the chemical reaction and equation?
When marble (calcium carbonate) is heated, it undergoes thermal decomposition to produce calcium oxide (quicklime) and carbon dioxide gas. The chemical equation for this reaction is: CaCO3(s) -> CaO(s) + CO2(g).
Give equations to represent the following reactions.(a) Borax is heated with CaO?
The chemical equation to represent the reaction between borax (Na2B4O7) and CaO (calcium oxide) when heated is: Na2B4O7 + CaO → CaB4O7 + Na2O In this reaction, borax and calcium oxide react to form calcium tetraborate (CaB4O7) and sodium oxide (Na2O) as the products.
What will happen when limestone is heated at a high temperature?
It will decompose according to: CaCO3(s) --> CaO(s) + CO2
What happen when borax is heated strongly?
When heated borax undergoes various transitions,first it loses water molecules and swells,then it turns into a transparent liquid solidifying to for a glass like structure called borax beads. Na2B4O7.10H20 -->heating Na2B4O7 -->heating 2NaBO2 + B2O3 BORAX SODIUM BORIC METABORATE ANHYDRIDE
What will happen if borax was on your arm?
Borax is harmless.
When did Cao Cao's invasion of Xu Province happen?
Cao Cao's invasion of Xu Province happened in 193.
What happens when borax is heated?
When heated borax undergoes various transitions,first it loses water molecules and swells,then it turns into a transparent liquid solidifying to for a glass like structure called borax beads. Na2B4O7.10H20 -->heating Na2B4O7 -->heating 2NaBO2 + B2O3 BORAX SODIUM BORIC METABORATE ANHYDRIDE
What happen when hydrated borax is heated strongly?
On heating, borax first loses water molecules and swells up.On further heating it turns into a transparent liquid, which solidifies into glass like material known as borax bead. Na2B4O7.10H2O -----heat------>Na2B4O7------heat------>2NaBO2+B2O3 Sodium Boric metaborate anhydride
When did Tran Cao rebellion happen?
Tran Cao rebellion happened in 1516.
When did Rebellion of Cao Qin happen?
Rebellion of Cao Qin happened in 1461.
What happened carbonate heated?
A thermal decomposition reaction occur:CaCO3 = CaO + CO2
What is the chemical equation of CaCO3 heated to form CaO and CO2?
It depends on the reaction temperature. At 298K, the heat of reaction is 179 kJ/mol
If you take borax and boiling water and make crystals is this a physical change or a chemical change?
It is a chemical change, because the borax reacts to the heated water.
