It should be noted that A compound is a new substance with unique chemical and physical properties formed when two or more elements are chemically bonded during a physical reaction.
Answer:
0.016 moles of product will obtain.
Explanation:
Given data:
Moles of K = 0.032 mol
Moles of product = ?
Solution:
Chemical equation:
4K + O₂ → 2K₂O
Now we will compare the moles of K with K₂O.
K : K₂O
4 : 2
0.032 : 2/4 ×0.032 = 0.016 mol
0.016 moles of product will obtain.
<span>This is because the theory is supported by the <span>Doppler</span> shift effect phenomenon observed in the universe. The Doppler shift effect shows the galaxies are continually moving away from each other , meaning they were once close together, and probably a singularity in the beginning as explicated in Big Bang Theory, and that a force/energy is driving them further apart.</span>
