The first option Forsure .
The osmium with a density of 22.6g/cm3 has a volume in cm3 of 0.965 cm3
The density formula and the procedure we will use is:
ρ = m/v
Where:
- v= volume
- ρ= density
- m= mass
Information about the problem:
Applying the density formula and isolating the volume (v), we get:
ρ = m/v
v = m / ρ
v = 21.8 g / 22.6g/cm3
v = 0.965 cm3
<h3>What is density?</h3>
It is a physical quantity that expresses the ratio of the body mass to the volume it occupies.

The statement that is true among the given statements is ΔH1 = 2ΔH2. The correct option is d. ΔH1 = 2ΔH2
From the question,
We are to determine which of the given statements is true.
From the given reactions,
We have
1. N2 (g) + O2 (g) ----> 2NO (g) ΔH1
and
2. 1/2 N2 (g) + 1/2 O2 (g) ---> NO (g) ΔH2
ΔH1 is the enthalpy change for reaction 1
and
ΔH2 is the enthalpy change for reaction 2
Enthalpy is an extensive property. The enthalpy change for a given reaction depends on the stoichiometry of the reaction.
From the given equations,
We can observe that the stoichiometry of reaction 1 is twice that of reaction 2.
Therefore, the enthalpy of reaction 1 will also be twice the enthalpy of reaction 2
That is,
ΔH1 = 2ΔH2
Hence, the statement that is true among the given statements is ΔH1 = 2ΔH2. The correct option is d. ΔH1 = 2ΔH2

Lose 1 electron
It will give it to an atom with more electrons. For example, Lithium (which has 1 valence electron) would give it to an atom that has more than 4 valence electrons
