Quartz is the type of mineral used for both mechanical and chemical weathering
Answer:
fossil fuels are non-renewable resources .
Hydrogen is the limiting reactant because when doing a stoichiometry equation for the reactants, hydrogen will be used completely by having a smaller yield and oxygen will be excess (7 moles to be exact)
This is false, because copper is an element.
To be solution, it has to have at least 2 different substances. Solid solution of metals is often called alloy.
Answer:
28,125 g
Explanation:
m(O₂) = 100 g
n(O₂) =M(O₂)/m(O₂)=32 gram per mole / 100 g = 0,32 mole
O₂ + 2H₂ ⇒ 2H₂O , n(H₂O) = 2 × n(O₂)
m(H₂O) = M(H₂O)/2 × n(O₂) = 18 grams per mole / 2 × 0,32 mole = 28,125 g
