Answer: A. There will be fewer producers in that area.
Explanation: Answer A is correct because all plants, including grass, is a producer. Since there is an increase in grass eating animals (Antelope), more grass will be consumed, decreasing the amount of grass aka producer.
The mass of piece of sterling silver jewelry is 33.24 g. It contains 92.5% silver Ag by mass. Since, sterling silver is an alloy of Ag-Cu thus, percentage of Cu will be:
% Cu=100-92.5=7.5%
Thus, mass of copper will be:
Molar mass of Cu is 63.546 g/mol, thus, number of moles of Cu can be calculated as follows:
Here, m is mass and M is molar mass.
Putting the values,
Now, in 1 mole of Cu there are 
thus, in 0.03923 mol, number of Cu atoms will be:
Thus, number of atoms of Cu will be
.
Answer:
<u>49 moles of atoms</u>
Explanation:
There are 7 individual atoms in each molecule of H2SO4: (2 hydrogens + 1 sulfur + 4 oxygens).
Therefore, if 7 moles are decomposed, there would be 7 times that amount of individual atoms:
7 x 7 = 49 moles of atoms
