The limiting reagent will be Al
<h3>What are limiting reagents?</h3>
They are reagents that limit the quantity of products that are formed in reactions.
From the equation of the reaction:
The mole ratio of Al to O2 is 4:3.
With 2 moles of Al and 2 moles of O2, Al becomes limiting while O2 is in excess.
With 2 moles of O2, the amount of Al required should be:
2 x 4/3 = 2.67 moles.
With 2 moles of Al, the amount of O2 required should be:
2 x 3/4 = 1.5 moles
Thus, O2 is in excess by 0.5 moles.

Answer:
A solid metal bead of the same size is dropped into the same cup and sinks to the bottom of the cup. How do the pebble and the metal bead compare? They both have the same mass. They are both denser than water.

Answer:
The flame will burn out
Explanation:
The oxygen will be kept out of the jar, without oxygen the flame cannot last long. The flame will eventually burn out. Nitrogen gas has no role to play in the burning. Nitrogen slows down the burning rate.
C
high specific heat capacity means water stores a lot of heat
when it is hot outside, water stores the heat, causing it to not be as hot as it could be without water
when it is cold outside, the heat from inside the water is transfered outside so that the temperature isn't as cold as it could be
so A and B are wrong (opposite)
In the case of internal temperature, the high specific heat of water should prevent variation, but I'm not too sure
<span>The
equilibrium constant is a value which represents the equilibrium of a reaction.
It is a reaction quotient when the reaction reached equilibrium. If Keq is
greater than 1, the mixture contains mostly the products. On the other hand, if
Keq is less than 1, the mixture contains the reactants. For this case, the equilibrium is towards the reactants or to the left.</span>
