Answer:
liquids: water and soda
gases: oxygen and carbon dioxide
solid: a chair and a notebook
To find AH°rxn, we use the following equation:
What we're going to do is to sum the enthalpy of the products and then substract with the enthalpy of the reactives:
As you can see, we need to multiply by the coefficients of the reaction.
Now, just replace the values of the table:
So the answer is -822.2kJ/mol.
For b:
Now, just replace the values of the table:
The answer for b is -1036kJ/mol.
Deposits
Explanation:
Glaciers also deposits materials in new places when they melt.
- Glaciers are made up of snow flakes that has compressed through time.
- In temperate and polar regions where they are prevalent, they are powerful agents of denudation.
- They can erode, transport and deposit earth materials in places.
- When a glacier retreats by melting, it deposit some of its materials in new places.
- Most of this sediment are called tillites.
- They are made up of unsorted materials of different size grains.

Answer:
1
Explanation:
Using the Rydberg formula as:
where,
λ is wavelength of photon
R = Rydberg's constant (1.097 × 10⁷ m⁻¹)
Z = atomic number of atom
n₁ is the initial final level and n₂ is the final energy level
For Hydrogen atom, Z= 1
n₂ = 2
Wavelength = 410.1 nm
Also,
1 nm = 10⁻⁹ m
So,
Wavelength = 410.1 × 10⁻⁹ m
Applying in the formula as:
Solving for n₁ , we get
n₁ ≅ 1
