Which of these oxides will likely form a colored solution when dissolved in water?
Alik [6]

Mn₂O

Explanation:

The oxide that will most likely form colored solutions is Mn₂O.

This is because most transition metals form colored compounds. Manganese is a transition metal belonging to the d-block on the periodic table.

  • Other examples of transition metals are scandium, titanium, iron, copper, cobalt, nickel, zinc
  • They belong to the d-block on the periodic table.
  • They have variable oxidation states.
  • Most of their solutions are always colored.

What volume will be occupied by 33.0 grams of CO2 at 500 torr and 27 °C?
wlad13 [49]

Answer:

V = 27.98 L

Explanation:

Given data:

Mass of CO₂ = 33.0 g

Pressure = 500 torr

Temperature = 27°C

Volume occupied = ?

Solution:

Number of moles of CO₂:

Number of moles = mass/molar mass

Number of moles = 33.0 g/ 44 g/mol

Number of moles = 0.75 mol

Volume of CO₂:

PV = nRT

R = general gas constant = 0.0821 atm.L/ mol.K  

Now we will convert the temperature.

27+273 = 300 K

Pressure = 500 /760 = 0.66 atm

By putting values,

0.66 atm×V = 0.75 mol × 0.0821 atm.L/ mol.K  × 300 K

V = 18.47 atm.L/0.66 atm

V = 27.98 L
