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.


Which have the highest boiling point mgo and cao or nacl and hcl or co2 and so2?

MgO and CaO have higher boiling points compared to NaCl and HCl, and CO2 and SO2. This is because MgO and CaO are ionic compounds that have stronger electrostatic forces between ions, leading to higher boiling points. NaCl and HCl are also ionic compounds but have lower boiling points compared to MgO and CaO. CO2 and SO2 are molecular compounds with weaker intermolecular forces, resulting in lower boiling points compared to the ionic compounds.


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 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%


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


How many moles are in 106 grams of MgO?

To determine the number of moles in 106 grams of MgO, you need to divide the given mass by the molar mass of MgO. The molar mass of MgO is 40.3 g/mol (24.3 g/mol for Mg + 16 g/mol for O). Thus, 106 g / 40.3 g/mol = approximately 2.63 moles of MgO.


How many moles of MgO are produced from 11.2 L O2?

To determine the number of moles of MgO produced from 11.2 L of O2, you would first need to balance the chemical equation for the reaction involving MgO and O2. Then, using the ideal gas law and stoichiometry, you can calculate the moles of MgO produced.


How many moles are present in 1g of MgO?

2 Mg(OH)2 have 10 atoms.


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.


What is the common element in MgO Al2O3 and CaO?

The common element in MgO (magnesium oxide), Al2O3 (aluminum oxide), and CaO (calcium oxide) is oxygen. All three compounds consist of a metal cation (magnesium, aluminum, or calcium) combined with oxygen anions. This results in the formation of metal oxides, which are typically ionic compounds. Additionally, they all exhibit properties common to metal oxides, such as high melting points and basic character.


How many moles are present in 160g of MgO?

To determine the number of moles in 160g of MgO, you first need to calculate the molar mass of MgO, which is 40.3 g/mol for Mg and 16.0 g/mol for O. Adding these together gives a molar mass of 56.3 g/mol for MgO. Next, divide the given mass (160g) by the molar mass of MgO to find the number of moles present. So, 160g / 56.3 g/mol = 2.84 moles of MgO.
