Answer:
a ship floats because of the mass and the parts of the ship help with staying on top of the water the buoyancy force is helpful for the ship to float which means weightless-airlessness and lightness.
Explanation:
The statements that best describes an unintended environmental consequence of aquaculture fish-farm enclosures located in estuaries is Aquaculture enclosures can harbor parasites that can negatively affect wild populations that breed in estuaries.
<h3>What is an estuary?</h3>
An estuary can be regarded as partially enclosed, water body which consists of mixture of freshwater from rivers as well as salt water from the ocean.
However, unintended environmental consequence of aquaculture fish-farm enclosures located in estuaries is that parasite can be easily decrease the populations of breed.

Answer:
The problem tells you that
6 g
of hydrogen gas,
H
2
, react with an unknown mass of oxygen gas,
O
2
, to form
54 g
of water.
As you know, the law of mass conservation tells you that the in a chemical reaction the total mass of the reactants must be equal to the total mass of the products.
In your case, this can be written as
total mass of reactants
m
H
2
+
m
O
2
=
mass of product
m
H
2
O
This means that the reaction must have consumed
