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
m
O
2
=

=
54 g
−

Explanation:
The sustainable use is using heavy metals from old cell phones is Recycling.
<h3>What are heavy metal?</h3>
The heavy metal is any chemical element that has a relatively high density, metal characteristics and is poisonous at lower concentrations.
The cell phones of sustainable use are recycled, uses less energy. Also, they have efficient charging, durability. The sustainable phones are easy and inexpensive to repair.
From recycling of one million cell phones, 75 pounds of gold, 772 pounds of silver, 33 pounds of palladium, and 35,274 pounds of copper is recovered. The sustainable cell phones may also contain tin, zinc, and platinum that are recycled for further use.
