A catalyst can cause a reaction to occur that does not normally happen at room temperature by reducing the activation energy needed to undergo the reaction.
<h3>What is a catalyst?</h3>
Catalysts are substances, often enzymes, used to speed up or commence a chemical reaction. They do this by reducing the necessary energy amount needed to begin the reaction, known as activation energy, or simply by changing the way in which the reaction takes place, which can allow for a reaction to take place even at <u>room temperature </u>when it would otherwise not occur.
Therefore, we can confirm that a catalyst can cause a reaction to occur that does not normally happen at room temperature by reducing the activation energy needed to undergo the reaction.

Answer:
yeesss. I am sooooo ssaaaddddd
The lack of an outlet will affect the composition of these lakes by causing an accumulation of organic and inorganic nutrients due to decomposition of living materials.
<h3>What is a lake?</h3>
Lake is a small stream of running water or a channel for water.
Lakes are usually a standing body of water or slow moving. This means that some lakes, including the Great Salt Lake and the Dead Sea, have no outlet.
The lack of an outlet will affect the composition of these lakes by causing an accumulation of organic and inorganic nutrients due to decomposition of living materials.

Actually, we can answer the problem even without the first statement. All we have to do is write the reaction for the production of sulfur trioxide.
2 S + 3 O₂ → 2 SO₃
The stoichiometric calculations is as follows:
6 g S * 1 mol/32.06 g S = 0.187 mol S
Moles O₂ needed = 0.187 mol S * 3 mol O₂/2 mol S = 0.2805 mol O₂
Since the molar mas of O₂ is 32 g/mol,
Mass of O₂ needed = 0.2805 mol O₂ * 32 g/mol = 8.976 g O₂
