Answer:
Hydrogen Peroxide
Explanation:
Hydrogen peroxide is a chemical compound with the formula H₂O₂. In its pure form, it is a very pale blue, clear liquid, slightly more viscous than water. Hydrogen peroxide is the simplest peroxide. It is used as an oxidizer, bleaching agent, and antiseptic. Concentrated hydrogen peroxide, or "high-test peroxide", is a reactive oxygen species and has been used as a propellant in rocketry. Its chemistry is dominated by the nature of its unstable peroxide bond.
The limiting reactant is Cl₂ (chlorine).
Explanation:
We have the following chemical reaction:
2 Al (s) + 3 Cl₂ (g) → 2 AlCl₃ (s)
And we start with 2.7 g of Al and 3.12 g of Cl₂.
First we calculate the number of moles of each reactant.
number of moles = mass / molar weight
number of moles of Al = 2.7 / 27 = 0.1 moles
number of moles of Cl₂ = 3.12 / 71 = 0.044 moles
From the chemical reaction we see that 2 moles of Al are reacting with 3 moles of Cl₂ so 0.1 moles of Al are reacting with 0.15 moles of Cl₂ which is a quantity higher than our available one of 0.044 moles of Cl₂. The limiting reactant is Cl₂.

Answer:
The pressure will be halved with respect its initial value
Explanation:
Based on Boyle's law, <em>the pressure exerted by a quantity of an ideal gas is inversely proportional to the volume it occupies if the temperature and remains constant</em>
<em />
Thus, if volume of a gas is doubled while the temperature is unchanged, <em>the pressure will be halved with respect its initial value</em>
