Answer:
2.04 mol
Explanation:
At STP, 1 mole = 22.4 L
45.6 L of H2 * (1 mole of H2 / 22.4 L ) = 2.04 mol
Answer:
9 Moles
Explanation:
C2H6 has 6 Hydrogens and Water Has 2 Hydrogens
so it takes 1 mole ethane to produce 3 moles water
1 Mole Ethane ----> 3 Moles Water so 3 ----> 9 moles

Explanation:
According to law of conservation of mass, the mass can neither be created nor destroyed.
Hence, for a chemical equation the left hand side should be equal to the right hand side.
Therefore, the two balanced equations are;
2 CO + O₂ → 2 CO₂
C₂H₄ + 3 O₂ → 2 CO₂ + 2 H₂O
Answer:
D) both the solid and the liquid phase
Explanation:
Metallic substances will conduct electricity in both the solid and liquid phase. Metals are generally conductors of heat and electricity.
- In metals there are free mobile electrons the enables the flow electricity.
- The free mobile electrons is utilized by the metals to conduct electricity.
- Metals generally have metallic bonds that holds their particles together.
- The metallic bonds enables metals to have a sea of delocalized electrons.
- Metals have a large atomic radius and larger electron pool.
