Is quicklime a pure substance?
Quicklime is prepared industrially and is fairly pure -CaO. However, strictly speaking there are always impurities present such as MgO, CaCO3, Ca(OH)2 and other trace elements.
What does molten slag contain?
molten slag mainly contain CaO, MgO, FeO, SiO2 etc.
How many moles are in 106 grams of MgO?
(106 g MgO / 1) * ( 1 mol MgO / 40.3044 g MgO) = 2.63 mol MgO.
What is mgo stand for?
If "mgo" is supposed to be a chemical formula, it should be written as MgO and then stands for magnesium oxide.
What is the compound of mgo in chemistry?
MgO, magnesium oxide an ionic compound
What is the long form of- CaO- P205- MgO-Si O2?
CaO is calcium oxide. P2O5 is diphosphorous pentoxide. MgO is magnesium oxide. SiO2 is silicon dioxide.
What is in cement?
Cement consists of the following composition,Cao - 60 -67 %SiO2 - 17-25%Al2O3 - 3-8%Fe2O3 - 0.5-6%MgO - 0.1-4%Alkalies - 0.4-1.3%SO3 - 1-3%
Which have the highest boiling point mgo and cao or nacl and hcl or co2 and so2?
swiggiity swag mgo is the drag
What is the soundness of cement?
soundness is nothing but volumetric change of the cement .Presents of chemicals such as CaO,MgO will react with the water present in the cement paste and it will increase the volume of cement paste while hardening.It may causes cracks in the building to avoid that it is necessary to find the soundness of cement before using that.It may vary to each type of cement even for each batch.Soundness should not exceed 10mm for OPC.
What is self fluxing?
Generally the Iron ore contains Silica as main gangue material. To remove silica in the form of Slag, we add CaO or MgO as flux material. But if the ore itself have the higher content of CaO or MgO along with Silica, the ore will be SELF FLUXED and no need to add external Flux. So, the self fluxing is an advantage in the case of iron ores having CaO or MgO in gangue.
Chemical reaction examples?
Fire Burning,Iron Rusting
How can you separate calcium oxide to its components?
By the reduction of calcium oxide you can prepare calcium: CaO + Mg = Ca + MgO 3CaO + 2Al -> Al2O3 + 3Ca
Oxides will react with hydrochloric acid but not with aqueous sodium hydroxide?
co --carbon monoxide
What are five realistic examples of ionic bonding?
Ionic bonding: NaCl, KBr, CuCl2, LiCl, NaI Covalent bonding: SiO2, CaO, MgO, UO2, ThO2
Difference between acidic pellets and basic pellets?
if the ratio of (Cao+Mgo)/(Al2o3+Sio2) >0.3 then the pellet is called as Basic pellet if it is less it is called Acidic pellet
Is dolomitic limestone same as agricultural limestone or horticultural hydrated limestone?
dolomitic limestone is different from agricultural or hydrated limestone the difference is in the MgO content and hardness Dolomitic Limestone is harder than both and its MgO content is higher. The CaO is lower in Dolomitic limestone and High in the later.
A stone roof is supported by collumns made up of limestone why might this be unsafe after a fire in a building explain the chemical process involved in the weakening of the structure?
Limestone is CaCO3. Let us decompose it:CaCO3 ---> CaO + CO2Heating the limestone will cause the above reaction to take place and replace the relatively firm structure of the limestone rock with a more powdery structure of the CaO. Another example might be this:Mg + (1/2)O2 ---> MgOThe relatively hard structure of the magnesium metal is replaced by a powdery MgO and the MgO structure falls apart into a heap of MgO dust.Source(s):ChemTeam
