What is the enthalpy of cadmium carbonate and cadmium oxide?
The enthalpy of cadmium carbonate (CdCO3) is -867 kJ/mol, and for cadmium oxide (CdO) it is -136 kcal/mol.
A metal forms two oxidesThe higher oxide contains 80 percent metal 0.72g of lower oxide gave 0.8g of the higher oxide when oxidised Show that the data illustrates the law of multiple proportions?
To show the law of multiple proportions, we can calculate the ratio of the masses of the higher oxide produced from the same mass of the metal in the lower oxide. For the lower oxide: 0.72g of lower oxide contains 20% non-metal, so the metal content is 80%. For the higher oxide produced: 0.72g of lower oxide gives 0.8g of higher oxide, which means the mass ratio is 1:1, consistent with the law of multiple proportions.
What compound has a lower percent of mass by nitrogen- NO or N2O3?
The oxide N2O3 has a lower percent of mass nitrogen.
How much energy is involved in the formation of 5 grams of rust?
The energy involved in the formation of 5 grams of rust can be calculated using the enthalpy of formation of iron(III) oxide (rust), which is -824 kJ/mol. First, convert the mass of rust to moles, then use the molar enthalpy of formation to calculate the energy involved.
Does aluminum melt at a higher temperature than aluminum oxide?
Aluminum oxide has a higher melting point than aluminum. Aluminum oxide melts at around 2072°C, while aluminum melts at a lower temperature of around 660°C.
Lattice enthalpy of magnesium oxide and sodium chloride?
The lattice enthalpy of sodium chloride is 789 kJ/mol.
What is the enthalpy of cadmium carbonate and cadmium oxide?
The enthalpy of cadmium carbonate (CdCO3) is -867 kJ/mol, and for cadmium oxide (CdO) it is -136 kcal/mol.
What is the synthesis of phenyl acetaldehyde from styrene oxide please give detail process?
To synthesize phenyl acetaldehyde from styrene oxide, you can first reduce styrene oxide using a reducing agent like lithium aluminum hydride to form 2-phenylethanol. Next, oxidize 2-phenylethanol using a mild oxidizing agent such as pyridinium chlorochromate to obtain phenyl acetaldehyde. Both steps need to be conducted under appropriate conditions to ensure successful conversion.
How do you convert acetic acid to acetaldehyde?
Acetic acid can be converted to acetaldehyde using an oxidizing agent such as silver oxide or chromic acid. The reaction involves breaking the carbon-carbon bond in acetic acid to form acetaldehyde as a primary product. This reaction is commonly known as dehydrogenation of acetic acid.
What are 10 gases?
Argon, Ether, Oxygen, Hydrogen, Methane, Nitrogen, Helium, carbon dioxide, Nitrous Oxide, carbon monoxide, xenon, Neon, Radon, Krypton, Chlorine, Ozone, Fluorine, Acetaldehyde,

The oxide N2O3 has a lower percent of mass nitrogen.
Why does calcium oxide react with silicon oxide to form slag?
Calcium oxide reacts with silicon oxide to form slag because the calcium oxide is a strong base that can react with acidic silicon oxide to form calcium silicate, which is a compound that has a lower melting point than the individual oxides. This helps to lower the overall melting point of the mixture and promotes the separation of impurities from the desired metal during the smelting process.
What is the bond length of nitrous oxide?
This might not be of much help, but it is longer than Nitrogen monoxide, as the bond enthalpy is higher in a N-O bond. There is not much on this issue on the Internet unfortunately.
What is the difference between nitrous oxide and halothane in relation to blood solubility?
nitrous oxide : lower solubility halothane : higher solubility

What is the balanced symbol equation for converting limestone into calcium oxide?
The balanced symbol equation for converting limestone (CaCO3) into calcium oxide (CaO) is: CaCO3 (s) -> CaO (s) + CO2 (g)
