B. elements
It's called the periodic table (of the elements)
Centimeters are units of length.
- P2H2 Oxidation State - Diphosphene
P2H2 has an oxidation number of +1. In P2H2, the oxidation
number of H is -1
- H2C2O4 Oxidation State - Oxalic Acid
C has an oxidation number of +3 in H2C2O4. O has an oxidation
number of -2 in H2C2O4. H2C2O4 has an oxidation number of +1.
- CrO2 Oxidation State - Chromium(IV) Oxide
CrO2 has an oxidation number of +4.
<h3>Explain oxidation?</h3>
The oxidation state, also known as the oxidation number, is an atom's hypothetical charge if all of its bonds to other atoms were fully ionic.
The sum of the oxidation states of all the atoms in an ion equals the ion's charge.
A substance's more electronegative element is given a negative oxidation state. The one that is less electronegative is given a positive oxidation state.

Answer:
474.3 cm³
Explanation:
Given data:
Initial volume of chlorine gas = 568 cm³
Initial temperature = 25°C
Final volume = ?
Final temperature = -25°C
Solution:
Initial temperature = 25°C (25+273 = 297 K)
Final temperature = -25°C (-25 +273 = 248 K)
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 568 cm³ × 248 K /297 K
V₂ = 140864 cm³.K / 297 K
V₂ = 474.3 cm³
