Explanation:
Answer:
The answer to your question is 0.98 g of H₂
Explanation:
Data
mass of H₂ = ?
mass of Zn = 31.8 g
Balanced chemical reaction
Zn + H₂SO₄ ⇒ ZnSO₄ + H₂
Process
1.- Calculate the molar mass or atomic mass of Zinc and hydrogen
The Atomic mass of zinc = 65 g
The Molar mass of H₂ = 2 g
2.- Use proportions and cross multiplication to find the mass of H₂ formed.
65 g of Zn ----------------- 2 g of H₂
31.8 g of Zn -------------- x
x = (31.8 x 2) / 65
x = 63.6/65
-Result
x = 0.98 g of H₂
Answer:

A Barometer is used to mesure atmosphereic pressure
Answer: The name of the above compound is Hexane
Explanation: The Formula for Homolougous series i.e Alkane family is CnH2n+2
The number of the Carbon above is 6 and the number of the Hydrogen is 14.
That means it corroborates with the above formula for the alkame family
C6H(2×6)+2 =C6H12+2
Final answer is C6H14
From the number 6 means "Hex" with the family name "ane"
The name results to Hexane
