1.5 moles of gas
Reaction of Al with to form is given below...
2 Al + 1.5 →
Here, 2 moles of Aluminum reacts with 1.5 moles of
atomic weight of aluminum = 27 g / mole
so, 1 mole of aluminum contains 27 g
then how many moles are there if it has 54 g in it.
moles of aluminum in 54 g = 54/27 = 2 moles
As per the equation mentioned above,
2 moles of aluminum reacts with 1.5 moles of .
∴1.5 moles of oxygen gas (02) are needed to completely react with 54.0 g of aluminum.

Answer:
Newton's third law
Explanation:
A fish swimming uses its fins to push the water backward making it swim forward is obeying Newton's third law of motion.
<em>Newton's third law of motion states that "action and reaction are equal and opposite". </em>
When the fish uses its fin to push the water backward, it reacts by being propelled in the opposite direction which is in the forward sense.
The third law is clear indicator that forces are always in pairs. As the fish swims, a net force between the oppositely directed forces do not cancel out.
For the empirical formula I got H28C1
I’m not sure how to do the others sorry
It would be plastic Becaus we can recreate things with plastic and other things that are recyclable. Since,we mostly cut down trees everyday for paper,not knowing that we are wasting natural resources, and destroying animal homes and food.
