The mass is simply the product of volume and density. But
first, let us convert the volume into cm^3 (cm^3 = mL):
volume = 2.5 cups * (240 mL/cup)
volume = 600 mL = 600cm^3
So the mass is:
mass = 600 cm^3 * (1 g / cm^3)
<span>mass = 600g</span>
It would be solid
hope this helps
Answer:
A. One unpaired electron
B. 5 unpaired electrons
Explanation:
In A ,Fe is in +3 oxidation state and Electronic configuration- [Ar]3d5
And NO2 is a strong field ligand hence it causes pairing in t2g orbitals and results one unpaired electron in dZX orbital.
In B, also Fe is in +3 oxidation state but F is weak field ligand hence causes no pairing of Electrons hence it results 5 unpaired electrons with electronic configuration t2g^3 eg^2
Answer:
Explanation:
a) Volume of the gas nRT / P
= 1,04 X 8.3 X 298 / 11 X 10⁵ m³
= 233.85 x 10⁻⁵ m³
= 233 x 10⁻² L
2.33 L
P₁V₁ / T₁ =P₂V₂/T₂
(11 X 2.33) / 298 = (1 X 24.2) / T
T = 281.37 K
= 8.37 degree
b ) w = p x change in volume
= 10⁵ x ( 24.2 - 2.33 ) x 10⁻³ J
= 21.87 X 10² J
2187 J
q = n x Cp x (25 - 8.37 )
= 1.04 x 35.66x 16.63 J
= 616.65 J
ΔU = Q - W
= 616.65 - 2187 J
= - 1570.35 J
