<h3>Answer:</h3>

Single displacement reaction

<h3>Explanation:</h3>

Single replacement reaction is a type of reaction in which a reactive element displaces a less reactive element from its compound.
The reaction given above; Al + H₂SO₄ → Al₂(SO₄)₃ + H₂ is a single replacement reaction.
This is because Aluminium takes the place of hydrogen atoms in sulfuric acid to form aluminium sulfate and hydrogen gas.
Double replacement reaction is where cations or anions are exchanged between two compounds to form new compounds.
For example the reaction; NaCl(aq) + AgNO₃(aq) → NaNO₃(aq) + AgCl(aq) is a double displacement reaction.

12. In a gas mixture consisting of carbon dioxide (CO2) and nitrogen (N2), the carbon dioxide molecules have a root-mean-square

zaharov [31]

Answer:

The correct answer is option e.

Explanation:

The formula used for root mean square speed is:

$\nu_{rms}=\sqrt{\frac{3kN_AT}{M}}$

where,

$\nu_{rms}$ = root mean square speed

k = Boltzmann’s constant = $1.38\times 10^{-23}J/K$

T = temperature

M = Molar mass

$N_A$ = Avogadro’s number = $6.02\times 10^{23}mol^{-1}$

Root mean square speed of carbon dioxide molecule:

$\nu_{rms}= 550 m/s$

Temperature of the mixture = T =?

Molar mass of carbon dioxide = 44 g/mol = 0.044 kg/mol

$\nu_{rms}=550 m/s=\sqrt{\frac{3\times 1.38\times 10^{-23}J/K\times 6.022\times 10^{23}mol^{-1}T}{0.044 kg/mol}}$

T = 533.87 K

Root mean square speed of nitrogen molecule:

$\nu'_{rms}= ?s$

Molar mass of nitrogen = 28 g/mol = 0.028 kg/mol

$\nu'_{rms}=\sqrt{\frac{3\times 1.38\times 10^{-23}J/K\times 6.022\times 10^{23}mol^{-1}\times 533.87 K}{0.028 kg/mol}}$

$\nu'_{rms}=689.46 m/s\approx 689 m/s$

689 m/s is the root-mean-square speed of the nitrogen molecules in the sample.
