Answer:
The balanced chemical equation for this reaction is:
2HCl (aq) + FeS (s) -----> FeCl2 (aq) + H2S (g)
Explanation:
The maximum oxygen uptake is known as the VO2 max.
Answer:24.31
Explanation:Contribution made by isotope of mass 23.99= 23.99×78.99=1894.97
Contribution made by isotope of mass 24.99=24.99×10.00=249.9
Contribution made by isotope of mass 25.98=25.98×11.01=286.04
Total contribution=1894.97+249.9+286.04=2430.91
Average mass=2430.91÷100
=24.31
To find average atomic mass you multiply the mass of each isotope by its percentage, and then add the values up.
35 * 0.90 + 37 * 0.08 + 38 * 0.02 = 35.22
Average atomic mass closest to 35.22 amu.
Answer: The look of the Earth has changed over time but continents have always been part of the picture. They didn't always look the way they do today, but yes, there have always been continents on Earth. Earth's continents are constantly in motion, and by running the tape ... against southern Europe, while the Atlantic will be a far wider ocean than it is today. ... During the war, Hess had used sonar to map some areas of the ocean floor in detail. ... away from both sides of the mid-ocean ridge at the same rate.
