We use the given masses of the reactants to calculate the moles of Mn and Cl. Empirical formula represents the simplest mole ratio of atoms present in a compound.
Moles of Mn =
Moles of Cl = = 0.710 mol Cl
Simplest mole ratio:
So the empirical formula is
Answer: S (s) + O2 (g) => SO2 (g)
Explanation: Picture attached.
Answer: The correct statements are:
- Objects “fall” toward the center of Earth.
- Objects accelerate at a rate of 9.8 m/s each second.
- Objects are pulled by Earth more strongly than they pull on Earth.
Explanation:
The gravity of the earth is the force which attracts the object to the center of the earth. When the any object with mass falls under the action of the gravity attains the acceleration of 9.8 .
- Objects “fall” toward the center of Earth.
- Objects accelerate at a rate of 9.8 m/s each second.
- Objects are pulled by Earth more strongly than they pull on Earth.
