The answer to this is True
The reason why iron oxide has more mass than the iron is because Iron oxide has oxygen atoms, and pure iron does not.
When iron rusts and forms iron oxide, the iron oxide has more mass than the iron. Which statement correctly explains this
observation?
(A)Iron oxide has oxygen atoms, and pure iron does not.
(B)The oxygen atoms in iron oxide have more mass than the iron atoms in pure iron.
(C)The iron atoms in iron oxide have more mass than pure iron.
(D)There are more iron atoms in iron oxide than in pure iron.
When a chemical reaction takes place, other atoms are combined with pure elements to form compounds. This addition of another atom (oxygen) after reaction makes iron oxide formed heavier than pure iron.
Iron oxide is a chemical substance formed when pure iron rusts. The formation of iron oxide is a chemical reaction.
Hence, the correct answer to the question is; the iron is heavier because Iron oxide has oxygen atoms, and pure iron does not.

The advice that will be given in the purchase of crystal candlestick is to go to
Betty's Breakables if the price is above $25.00.
In this scenario, we were told that Betty's Breakables offers 40% discount,
while Annie Attic offers $10 discount.
<h3>Calculation</h3>
Let's assume the price is $25.00, the discount at Betty's Breakables will be
= 40/100 × $25.00
= $10.
At Annie Attic, he was offered a $10 discount which is the same. However
there will be more gain on the discount if the price is above $25.
Let's assume the price is $30 , the discount will be $12 at Betty's Breakables
which is more than that at Annie Attic in which the discount remains at $10.
It is therefore cheaper to go to Betty's Breakable if the price of the
candlestick is above $25.
