The number of mole of oxygen gas, O₂ in the cylinder given the data is 0.5 mole
<h3>Description of mole </h3>
The mole of a substance is related to it's mass and molar mass according to the following equation:
Mole = mass / molar mass
<h3>How to determine the mole of O₂</h3>
From the question given, the following data were obtained:
- Mass of O₂ = 16 g g
- Molar mass of O₂ = 32 g/mol
- Mole of O₂ =?
Mole = mass / molar mass
Mole of O₂ = 16 / 32
Mole of O₂ = 0.5 mole

<span>False. Almost all of the oxygen on Earth is found in the oceans.</span>
The volume of Hydrogen gas : 24 L
<h3>Further explanation</h3>
Given
16 L Ammonia(NH₃)
Required
The volume of Hydrogen gas
Solution
Reaction
N₂ + 3H₂ ⇒ 2NH₃
Avogadro's hypothesis:
In the same T,P and V, the gas contains the same number of molecules
So the ratio of gas volume will be equal to the ratio of gas moles
V₁/n₁=V₂/n₂
From the equation, mol ratio of H₂ : NH₃ = 3 : 2, so volume of H₂ :
= 3/2 x volume of NH₃
= 3/2 x 16 L
= 24 L
Answer:
A) Nonmetal carbon shares valence electrons with each nonmetal hydrogen forming four covalent bonds.
Explanation:
Methane is formed when nonmetal carbon shares valence electrons with each nonmetal hydrogen forming four covalent bonds. Nonmetals share electrons to form covalent bonds.
Good luck! :)
