41.9 g of MgO is produced in the reaction.
Given,
[tex]2Mg + O_2 = MgO[/tex]
Mass of Mg = 25g
Molar mass of Mg =24.3g
Moles of Mg=25/24.3=1.04
Mass of oxygen=25g
Molar mass of oxygen=32
Moles of oxygen=25/32=0.78
So, from above we can say that Mg is limiting reagent.
Moles of MgO =1.04
Molar mass of MgO =40.3
Mole =given mass/ molar mass
1.04 =mass/ 40.3,
Mass = 1.04×40.3=41.9 g
An activity that results in the chemical conversion of one group of chemical compounds into another is known as a chemical reaction. Chemical reactions are changes that traditionally only affect the locations of electrons in the formation and breakage of chemical bonds between atoms, with no change to the nuclei (i.e., the elements present). These changes are generally captured by a chemical equation. Chemical reactions between unstable and radioactive materials, where both electronic and nuclear changes may take place, are the focus of the subfield of chemistry known as nuclear chemistry.
Reactants or reagents are the material(s) that are initially incorporated into a chemical reaction.
