Find the molar mass of Fe_2O_3
2Fe = 2*56 = 112
3O = 3* 16 = 48
Molar Mass = 160 grams
moles= given mass / molar mass
moles = 28 / 160
moles = 0.175 <<<< answer
When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere. It could be A I’m not sure if this helps.
Answer: Option A
Explanation: 2 Na + Cl2---> 2NaCl
Here Oxidation no of Na is zero while in NaCl is +1. That means oxidation state of Na increased from 0 to +1 hence oxidation
While Cl2 has zero in molecular form and -1 in NaCl hence Reduction (Oxidation no decreased from zero to -1)
Halogens(cl) always shows -1 oxidation state and IA group elements(Na)shows +1 oxidation state
Answer:
Solubility, length, hardness, color, mass, density, weight, volume, boiling, and point.
