Twenty-four grams of magnesium metal reacts with sixteen grams of oxygen gas to form magnesium oxide. according to the law of conservation of mass, how much magnesium oxide will there be after the chemical change is complete? never mind i got it

The law of conservation of mass dictates that the total mass of reactants must be equal to the total mass of the products. Thus:

mass(MgO) = mass(Mg) + mass(O)

mass(MgO) = 24 + 16

mass(MgO) = 40 g

The answer is 40 g.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

it is a good conductor
