Law of Definite Proportions states that a compound is composed of the same ratio of elements present. The formation of water has a reaction:
H2 + 1/2 O2 = H2O
The limiting reactant would be the element with the least ratio of molar mass to stoichiometric coefficient, and that would be H2, not O2.
I don’t know the answer either
Proprietățile fizice ale mineralelor depind in cea mai mare măsură de compozitie chimică si structura reticulara reprezintă importanta deosebită în recunoașterea mineralelor
Answer:
If it is pure, the substance is either an element or a compound. If a substance can be separated into its elements, it is a compound. If a substance is not chemically pure, it is either a heterogeneous mixture or a homogeneous mixture. If its composition is uniform throughout, it is a homogeneous mixture.
