Answer:
1. volcano
4. glaciers
Explanation:
this isnt really helpful but there is 2 sorryy
Explanation:
The given data is as follows.
Enthalpy of vaporization,
= 38.56 kJ/mol
Temperature (T) = 
= (78.4 + 273) K
= 351.4 K
Now, we will calculate the change in entropy using the formula as follows.


= 
= 0.109 kJ/mol K
Thus, w ecan conclude that the entropy change for vaporization is 0.109 kJ/mol K.
Tetrahedral arrangement is resulted upon mixing one s and three p atomic orbitals, resulting in 4 hybridized

<h3>What is
orbital hybridization?</h3>
In the context of valence bond theory, orbital hybridization (or hybridisation) refers to the idea of combining atomic orbitals to create new hybrid orbitals (with energies, forms, etc., distinct from the component atomic orbitals) suited for the pairing of electrons to form chemical bonds.
For instance, the valence-shell s orbital joins with three valence-shell p orbitals to generate four equivalent sp3 mixes that are arranged in a tetrahedral configuration around the carbon atom to connect to four distinct atoms.
Hybrid orbitals are symmetrically arranged in space and are helpful in the explanation of molecular geometry and atomic bonding characteristics. Usually, atomic orbitals with similar energies are combined to form hybrid orbitals.

Answer:
D. 2NH₃(g) ⟶ N₂(g) + 3H₂(g)
Explanation:
A chemical equation must show the correct formulas for reactants and products.
A and B are wrong, because they have NH₃ as a product.
C is wrong. H₃ does not exist.
A is correct. The equation for the decomposition of ammonia is
2NH₃(g) ⟶ N₂(g) + 3H₂(g)
Answer:
λ = 5.56 × 10⁻³ m
Explanation:
You have to use the formula c = λv to solve the problem. Review what you are given. You are given v and c, where v = 5.40 × 10¹⁰ Hz and c = 3.00 × 10⁸ m/s. The value c is for the speed of light and is something you need to memorize. You will use it often in physics and sometimes in chemistry.
Now that you figured out what you know, you can see that there is only one unknown, allowing you to solve.
c = λv
λ = c/v
λ = (3.00 × 10⁸ m/s)/(5.40 × 10¹⁰ Hz)
λ = 5.56 × 10⁻³ m
