A geomagnetic storm (commonly referred to as a solar storm) is a temporary disturbance of the Earth's magnetosphere caused by a solar wind shock wave and/or cloud of magnetic field that interacts with the Earth's magnetic field.
Solar flares, coronal mass ejections, high-speed solar wind, and solar energetic particles are all forms of solar activity.
Answer:hey did you ever get an answer? I need it for this exam
Explanation:
Answer:
B. Na
Explanation:
To identify an atom, you simply need to look at the number of protons. This atom has 11 protons. On the periodic table, you can see that the element with 11 protons is sodium (Na).
Answer:
-122 J/K
Explanation:
Let's consider the following balanced reaction.
N₂(g) + 2 O₂(g) ⇒ 2 NO₂(g)
We can calculate the standard reaction entropy (ΔS°) using the following expression.
ΔS° = Σ ηp × Sf°p - Σ ηr × Sf°r
where,
- η: stoichiometric coefficients of products and reactants
- Sf°r: entropies of formation of products and reactants
ΔS° = 2 mol × 240.06 J/K.mol - 1 mol × 191.61 J/K.mol - 2 mol × 205.14 J/K.mol
ΔS° = -121.77 J/K ≈ -122 J/K
Chemical energy is kept inside the bonds that are connected to withatoms with other atoms and molecules with other molecules.
Because chemical energy is kept in likestorage. It is an shape of potential energy.
When a chemical reaction takes place, the stored chemical energy is let out.
