2.258625 *10²³ oxygen atoms will be produced.
<h3><u>Explanation:</u></h3>
Decomposition reaction is defined as the type of reaction where one single reactant breaks to produce more than one product only by means of heat or other external factor.
Formula of magnesium oxide = MgO.
The molecular mass of magnesium oxide = 24 +16= 40.
So in 40 grams of magnesium oxide, number of molecules is 6.023 * 10²³.
So in 15 grams of magnesium oxide,, number of molecules is 6.023 *1023 * 15/40 = 2.258625 *10²³.
From one molecule of magnesium oxide, one oxide atom will be produced.
So number of oxide atoms with 100% yeild = 2.258625 *10²³

Answer:
Benzene Hexachloride
Explanation:
BHC in benzene mean ''Benzene Hexachloride''.
<h2>B = Benzene</h2><h2>H + C = Hexachloride </h2>
As you can see, There are only two words and three letters. Even though it is one word, Hexa = H and Chloride = C
Iron(III) sulfide is the name of the compound written using the Stock system. In the Stock system (named for Alfred Stock) a Roman numeral is used to indicate the oxidation number of the metal. Roman numerals are used in the names of compounds where the metal exhibits two or more oxidation states.
The sum of the oxidation states of a compound must always be zero. The oxidation state of sulfide is -2, and the oxidation state of sulfur, we are told by (III) is +3. You can either use the "criss-cross" trick to get the subscripts where the oxidation number of Fe becomes the subscript of S, and the oxidation number of S becomes the subscript of Fe...
+3-2
.FeS --> Fe2S3 .
