What mass of CO2 can be produced from the decomposition of 4.8 moles of Fe2(CO3)3?

633.6 g of can be produced from the decomposition of 4.8 moles of

Explanation:

The balanced chemical equation for decomposition of is :

According to stoichiometry :

1 mole of produce = 3 moles of

Thus 4.8 moles of will rproduce=  of

Mass of

Thus 633.6 g of can be produced from the decomposition of 4.8 moles of

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
