4.  K₂O(s)+CO₂(g)⇒K₂CO₃(s)+energy
The energy level of the reactants is higher than the energy level of the products (you can see this with energy diagrams).

5. 2HgO(s)+energy⇒2Hg(l)+O₂(g)
the energy levels of the products is higher than the energy level of the reactants. (this can also be seen with energy diagrams)

How many times Father is Proxima Centauri from the sun then is earth from the sun answer choices about 269,000 times or about 0.
Bas_tet [7]

Answer:

269,000

Explanation:

The distance between Proxima Centauri and the Sun, d₁₁ = 4.246 light years

The distance between Earth and the Sun, d₂ = 1.58 × 10⁻⁵ light years

The ratio of the distances are;

d₁/d₂ = 4.246/(1.58 × 10⁻⁵) = 268734.177215 ≈ 269,000 times

Therefore, Proxima Centauri is approximately 269,000 times further from the Sun than the Earth is from the Sun
