Answer:
The volume increases,
Final volume is 2.1L
Explanation:
Based on Boyle's law, the absolute temperature of a gas is directly proportional to the volume of the gas.
As the balloon change increases its temperature, the volume increases
The Boyle's equation is:
V1T2 = V2T1
<em>Where V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.</em>

Replacing:
V1 = 2.0L
T2 = 35°C + 273.15 = 308.15K
V2 = ?
T1 = 25°C + 273.15 = 298.15K
2.0L*308.15K = V2*298.15K
2.1L = V2
<h3>Final volume is 2.1L</h3>

Answer:

Explanation:
Hello,
In this case, the undergoing chemical reaction is:

Next, we compute the reacting moles of each reactants:


Then, as magnesium and hydrohloric acid are in a 1:2 molar ratio 0.153 moles of magnesium will completely react with 0.306 moles of hydrochloric acid yet we only have 0.144 moles, therefore, limiting reactant is hydrochloric acid. Thus, we compute the produced moles of hydrogen:

Finally, we use the ideal gas equation with T=298K and 1atm (STP conditions) to compute the liters of hydrogen gas:

Best regards.
Answer:
A
Explanation: The real molecule is too small so had to build a model to make it viewable
