Answer:
its either C or D my guess is C though because 35.0g of hyddrogen is =1.03 mol
Explanation:
The metal is lead, Pb.
One unit of the oxide contains one atom of O (16.00 u).
∴ Mass of oxide = 16.00 u O × (100 u MO/7.17 u O) = 223.15 u MO
Mass of M = mass of MO – mass of O = 223.15 u -16.00 u = 207.2 u
The only element with an atomic mass of 207.2 u is lead (Pb) and the formula of the oxide is PbO.
Answer:
I would say A, Gravity can help erosion to occur.
Explanation:
While B,C,D do help cause erosion, that isn't the only way erosion can occur.
