E= hf
so shorter lambda = larger f= more energy
Answer is A
Answer:
All samples of a given chemical compound will be composed of the same elements in the same proportion.
Explanation:
The law of constant composition or definite proportions states that "all pure samples of the same chemical compound contain the same proportions of the elements by mass". For example, every time water H₂O forms, it would always have the same proportion of hydrogen and oxygen.
a) Oxidised. Oxygen transferred from CuO to Zn.
b) Reduced. Oxygen transferred from Iron oxide to Carbon.
c) Oxidised. Electrons transferred to
d) Reduced. Electrons are gained by $\mathrm{Cu^{+2}}$
