Question

Chemical reactions project modeling the conservation of mass pls help just need answer

Answer 1

The law of conservation of mass states that

In any chemical reaction mass is neither created nor destroyed rather it remains conserved

• Mass of reactants=Mass of products

Look the chemical reaction below

`\\ \sf\longmapsto 2H_2+O_2=2H_2O`

Count the mass on both sides and simplify

• It will be 18g and ratio remains one
