The answer here is B: Max Planck
N(CaCO3)=m÷M
m being the mass of the sample and M being the molar mass of the compound; Molar mass is to be obtained by adding the atomic masses of all the elements in the compound.
therefore,
n(CaCO3)=m÷M
=28g÷100 g.mol
=0.28 mol
therefore, there are 0.28 moles in 28g of Calcium Carbonate.
Answer: The equilibrium will shift to the left to favor the reverse reaction.
Explanation:
This is a direct application of Le Chatelier's principle.
Le Chatelier's principle predicts that if a chage is introduced in a system in equilibrium, the system will react to compensate the change.
The increase in the concentration of CO, which is in the right side of the chemical equation, takes the system out of the equilibrium.
Chemically, the greater number of molecules of CO means that more CO will react to favor the reverse reaction and restore the equilibrium with the increase of molecules in the left side (CH4 and H2O).
He stated that most of the mass of the atom is concentrated in the center of the atom which was against the plum pudding model, so he disproved to that
