Answer:
The electron configuration for Cr is [Ar]3d6 4s2 (note that 4s is higher in energy than 3d - that is important). Cr2+ means we remove 2 electrons, and we remove them from the highest energy level, which is 4s, so the electron configuration for Cr2+ is [Ar]3d6.
Explanation:
The answer is (4) amino acid. This molecule has one carboxyl and one amidogen linked at the same carbon atom. This is the property of amino acid. So this is an amino acid.
Answer:
Commonly from a guys perspective and where you live it can be 50/50. In the city life, your gal or lad will likely leave you for another boy or girl since there are more to choose from or rather date.
The volume occupied by the sample is 8.4 cm³
<h3>What is density?</h3>
The density is the ratio of mass of the object to its volume.
Given is the mass m =14.7 g and the density is 1.75 g/cm³, then the volume will be
ρ = m/ V
V =m /ρ
Substitute the values, we get
V = 14.7 /1.75
V = 8.4 cm³
Thus, the volume of the sample is 8.4 cm³.

Answer:
T₂ = 464.75 K
Explanation:
Given data:
Initial Temperature = 398.15 K
Pressure = 248 torr (constant)
Initial Volume = 275 mL (275/1000 = 0.275 L)
Final volume = 0.321 L
Final temperature = ?
Solution:
V₁/T₁ = V₂/T₂
T₂ = V₂ T₁ / V₁
T₂ = 0.321 L × 398.15 K / 0.275 L
T₂ = 127.81 L.K / 0.275 L
T₂ = 464.75 K
