Answer:
The answer is B. Limiting factors can lower birth rates, increase death rates.
When a pot of water sits on a hot stove, the metal pot is
heated, and then transfers its heat to the water. A student claims that
conduction is the only type of heat
transfer occurring. The statement that explains why the student’s idea is
incorrect Conduction cannot occur between two different phases of matter. The answer
is letter A.
The answer the the question is 22
1) since we are given percentages, we can assume we have 100 grams of the molecule.
55.6 % Cu ----> 55.6 grams Cu
16.4 % Fe------> 16.4 grams Fe
28.0% S--------> 28.0 grams S
2) convert each gram to moles using the molar masses given



3) we divide the smallest value of moles (0.293) to each one.
Cu --> 0.876 / 0.293= 3
Fe---> 0.293 / 0.293= 1
S-----> 0.875 / 0.293= 3
4) let's write the empirical formula
Cu₃FeS₃
