Answer:
30 g of magnesium would be combined with 20 g of oxygen. The law used solving this problem is the Lavoisier Law of conservation of mass.
Explanation:
If 60 g of magnesium combines with 40 g of oxygen to make 100 g of magnesium oxide, then 30 g of magnesium will combine with 20 g of oxygen to make 50 g of magnesium oxide.
This happens because in a chemical reaction there is no creation or descruction of atoms, only a rearrangement. Therefore, the mass of reactants should be equal to the mass of products.
The following equation represents the proportions of the substances:
Mg + 1/2O₂ → MgO
I believe it’s bacteria but your choice
I looked it up and got Precipitation
At STP the standard temperature is 273.15 K.
At STP the standard temperature is 0*C
Mass= mols x Molar mass
=1.00 mol x 61.0168 g/mol
= 61.02 grams
