In the atom model, the poppy seeds are placed in different places to represent the different position of electrons.
1.velocity-displacement. The first two equations of motioneach describe one kinematic variable as a function of time. ... Velocity is directly proportional to time when acceleration is constant (v ∝ t). Displacement is proportional to time squared when acceleration is constant (s ∝ t2).
This is not a scientific term. The scientific version is Nuclear ___. Depends on the context.
It depends on the unit though if its in miles per hour then you can simply divide 50 by 2
Answer:
Explanation:
The chemical equation considered is:
- <em>Zn(s) + 2H⁺ (aq) → Zn²⁺ (aq) + H₂(g)</em>
That is a redox reaction because one both oxidation and reduction are happening.
The element or species that is being reduced is that whose oxidation number is reduced.
On the left side, hydrogen, H, has oxidation number +1, which is shown by the superscrit + to the right of H: H⁺.
On the right side, hydrogen appears in its elemental form: H₂. Thus, its oxidation number is 0.
That means that the hydrogen ion is being reduced, and the half reaction that represents this is:
Which means that two H⁺(aq) ions gain 2 electrons to produce a molecule of H₂(g). The reduction reactions happen due to the gain of electrons.
