Answer:
'Oxidation states have changed.'
Explanation:
Redox Reactions can be identifiable by a change in oxidation number/states of two of the atoms in the reaction. Any reaction in which no oxidation numbers/state change is not a redox reaction.
Answer:
(B) The Jalican government did not intend the new fuel-efiiciency requirement to be a pollution-reduction measure.
Explanation:
What it was expressed is about to reduce dependence on imported oil.
Answer:
The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide.
<span><span>1. </span><span>Fe2O3 or Iron (III)
oxide is an organic compound. It contains 3 main oxides of Iron, the iron (II)
oxide (FeO) and the iron (II, III) oxide (Fe3O4).
Now, let’s find the number of Molecules are there in 79g of Fe203:
The number of Atoms are there:
Molar Mass of Fe2O3 = 160g / mol.
=> 160g of Fe2O<span>3 </span>= 6.02 x 1023 Molecules
=> 79g of Fe2O3 = x
Next, find the value of X, in where:
x = (6.02 x 1023 x 79g) / 160g is approximately
x = 2.97 x 1023 molecules.</span></span>
