<h3>
Answer:</h3>
12 moles
<h3>
Explanation:</h3>
The equation for the reaction;
CuO(s) + H₂(g) → Cu(s) + H₂O(g)
We are given;
- Moles of copper, Cu is 12 moles
We are required to calculate the number of moles of CuO required;
- From the reaction 1 mole of CuO reacts to produce 1 mole of copper
- Thus, the mole ratio of CuO to Cu is 1 : 1
- Moles of CuO = Moles of Cu
Thus, moles of CuO = 12 moles
Therefore; 12 moles of CuO will be required.
Answer:
λ = 1×10²⁶m
Explanation:
Given data:
Wavelength of radiation = ?
Frequency of radiation = 3×10⁻¹⁸Hz
Solution:
Formula:
c = f × λ
c = speed of wave = 3×10⁸ m/s
by putting values,
3×10⁸ m/s = 3×10⁻¹⁸Hz × λ
λ = 3×10⁸ m/s / 3×10⁻¹⁸s⁻¹
λ = 1×10²⁶m

The answer is: Survival of the form that will leave the most copies of itself in successive generations.
"Survival of the fittest" is a phrase that originated from Darwinian evolutionary theory.
This is example of natural selection and adaptation.
Genetic variation is important to the population's ability to survive in different situations that affect natural selection.
The environment is constantly changing and different alleles are favored.
