Answer:
32 meters
Explanation:
You use the formula a^2 + b^2 = c^2.
Plug in the length and hypotenuse.
60^2 + b^2 = 68^2
Simplify and Solve:
3600 + b^2 = 4624
4624 - 3600 = b^2
1024 = b^2
Sqrt 1024 = 32
b = 32
equation Fe3O4=Fe+CO2 is an impossible reaction
Answer:
D
Explanation:
When lead ions and sulfate ions bond, they form sediment so neither a nor b can be the answer.
The important thing is that two nitrate ions were originally bonded with one lead ion, while two potassium ions bonded with a sulfate ion.
Finally, since potassium and nitrate ions don't form sediment these two ions must remain. Therefore the answer is D
the correct answer would be the sun
