Answer:
Oxide mineral.
Explanation:
Oxide mineral are the minerals in which oxide anion () is bonded to one or more number of the metal ions.
Oxide minerals are naturally occurring compounds with structure based on the close-packed atoms of oxygen in which metal or other various ions occur in the interstices.
Examples are: anatase, brucite, etc.

Step One
Find the moles of HCl
C = 1.0 mol/L
V = 75 mL = 75 / 1000 = 0.75 L
Note the concentration is in Liters.
<em>Formula</em>
n = C*V
<em>Solve</em>
n = 1.0 * 0.075
n = 0.075 moles
Step two
Adjust the number of moles of HCl
How every mol of H2 produced, you will require 2 mol of HCl
2/1 = 0.075/x Cross multiply
2x = 0.075 Divide by 2
x = 0.075 / 2
x = 0.0375 moles of H2 <<<<<<<<< Answer
