Cyclopentane is NOT an isomer of pentane.
Isomers must have the same molecular formula.
The molecular formula of pentane is C₅H₁₂, while the molecular formula of cyclopentane is C₅H₁₀.
The two molecules cannot be isomers.
We can use the ideal gas law equation to find the volume of N₂ gas at STP
PV = nRT
where
P - standard pressure - 101 325 Pa
V - volume
n - number of moles - 21.0 g / 28 g/mol = 0.750 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - standard temperature - 273 K
substituting the values in the equation
101 325 Pa x V = 0.750 mol x 8.314 Jmol⁻¹K⁻¹ x 273 K
V = 16.8 L
volume of N₂ at STP is 16.8 L
Answer:
2) MgO ---→ Mg + O2
Explanation:
Chemical decomposition is defined as the breakdown or breaking of a single molecule or entity into two or more smaller fragments.
Chemical decomposition is usually regarded as the exact opposite of chemical synthesis. In most cases, the chemical reaction in which two or more products are formed from a single reactant is called a decomposition reaction.
