The answer is A, underground
The amount of sodium bromide that would be formed from the reaction will be 7.5524 grams
<h3>Stoichiometric calculation</h3>
Looking at the equation of the reaction:

The mole ratio of CuBr2 and NaCl is 1:2.
Mole of 16.4 grams of CuBr2 = 16.4/223.37
= 0.0734 moles
Mole of 22.7 grams of NaCl = 22.7/58.44
= 0.3884 moles
Equivalent mole of NaCl = 0.1468 moles
Thus, NaCl is in excess while CuBr2 is limiting.
Mole ratio of CuBr2 and NaBr = 1:1
Mass of 0.0734 mole NaBr = 0.0734 x 102.894
= 7.5524 grams

Answer:
Explanation
Hardness has been defined the level of difficulty with a smooth surface of a mineral may be scratched. The hardness of a mineral species is upon the strength of the bonds which compose its crystal structure Hardness is measured of how easily a material can be scratched or indented Hard materials are often very brittle.
