Hey There!!~
Your best answer choice is 10280 or 10,280.
Because, 1 x 1025 = 1025 + 3 = 1028 x 10 = 10280 or 10,280.
Hope This Helps....!!

Answer:
The coefficient of O2 is 11
Explanation:
Step 1:
The equation for the reaction:
FeS2 + O2 → SO2 + Fe2O3
Step 2:
Balancing the equation. The equation can be balance as follow:
FeS2 + O2 → SO2 + Fe2O3
There are 2 atoms of Fe on the right side and 1 atom on the left. It can be balance by putting 2 in front of FeS2 as shown below:
2FeS2 + O2 → SO2 + Fe2O3
There are 4 atoms of S on the left side and 1 atom on the right side. It can be balance by putting 4 in front of SO2 as shown below:
2FeS2 + O2 → 4SO2 + Fe2O3
Now, there are a total of 11 atoms of O on the right side and 2 atoms on the left side. It can be balance by putting 11/2 in front of O2 as shown below:
2FeS2 + 11/2O2 → 4SO2 + Fe2O3
Multiply through by 2 to clear the fraction as shown below:
4FeS2 + 11O2 → 8SO2 + 2Fe2O3
Now the equation is balanced.
The coefficient of O2 is 11
Explanation:
- Electrons are negatively charged particles that orbits the nucleus.
- Chemical and physical properties of elements are usually determined by the number of electrons they posses.
- Electrons are the basis of the chemical changes in which atoms undergo.
- Chemical properties of atoms are a function of the number of electrons they posses.
- When atoms combine, they do so in order to attain stability.
- Combination of atoms involves the loss or gain or sharing of electrons between atoms.
- When atoms combine with one another, they form chemical bonds.
- These chemical bonds can be between two atoms or between molecules.
- The nature of the chemical bonds determines the physical and chemical properties of a host of compounds.
- For example, metallic bonds in metals is responsible for their conductivity and malleability.
- It is also responsible for the wide range of reactions they undergo.
