Combustion reaction is defined as the reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule.
General equation for these reactions are given as:
Redox reaction is a type of reaction in which reduction and oxidation reaction takes place simultaneously. One substance goes oxidation reaction and another goes reduction reaction.
Combustion reactions are also termed as oxidation reactions because oxygen is getting added to both carbon and hydrogen atoms.
Hence, the correct answer is it is an example of combustion.
Answer:
3 moles
Explanation:
SrCO3
Mass = 442.8g
Molar mass = (87.6 + 12 * [16*3]) = 147.6g/mol
Number of moles = mass / molar mass
Number of moles = 442.8 / 147.6
Number of moles = 3
