i lowkey feel like im doing this whole chem exam for u lol. good luck anyway! u rock!
Answer:
See Explanation
Explanation:
From the parameters given here in this question;
n= 1.46 moles
P= 0.982 miles
T= 13°C + 273 = 286 K
R= 0.0821 L.atm/mol.K
We are to find the volume using the ideal gas equation which states that;
PV=nRT
V= nRT/P
V= 1.46 × 0.0821 × 286/0.982
V= 34.9 L
b) Boyle's law can be proven from the kinetic theory of gases. Boyle's law states the relationship between the volume and pressure of an ideal gas. Boyle's law states that the pressure of a given mass of ideal gas is inversely proportional to it's volume at constant temperature and pressure. This is the only correct statement among the options listed in the question.

Looking at the molecular formula of Cr₂O₃, we know that oxygen has an oxidation state of -2, and three oxygen atoms means they are providing a total charge of -6 to the species. Since the compound is charge-neutral overall, the two chromium atoms must have a total charge of +6 to balance the -6; therefore, each chromium atom must have a charge of +3. This means that the chromium atoms in this molecule are Cr³⁺. To name this compound we will refer to the metal as chromium(III), to give a full name of chromium(III) oxide.
Since chromium can have multiple oxidation states, such as Cr²⁺ or Cr⁴⁺, it is a Type II ion.
