Answer:
Bohr's model
Explanation:
Rutherford's experimental evidence best supports the Bohr's model. Recall that in the Bohr's model, the Rutherford model was regarded as a fundamental stepping stone.
Experimental evidence from the Bohr's model shows that the atom is not a sphere of positive charges in which negative charges were embedded. It would have been impossible for Neils Bohr to build the quantum theory from such a model.
Hence, the nuclear theory of Rutherford provided a fundamental stepping stone and experimental backup for the Bohr's model of the atom.
All other models mentioned in task 1 (Dalton, Thompson and Bohr) all mention the fact that the atom is made of particles. Thompson effectively described the particles as negative and positive in nature. Bohr took the idea further by proposing that the negative particles (electrons) were actually found in energy levels that are quantized.
Answer: 0.45 moles of
will be produced from 0.15 moles of propanol.
Explanation:
The balanced chemical reaction is:
is the limiting reagent as it limits the formation of product and
is the excess reagent.
According to stoichiometry :
2 moles of
produces = 6 moles of
Thus 0.15 moles of
will produce=
of
Thus 0.45 moles of
will be produced from 0.15 moles of propanol.
D. impermeable rocks
Explanation:
Impermeable rocks is the factor among the give choices that will increase the amount of water runoff on the surface.
Surface run-off is liquid water that flows and moves on the earth surface.
- An impermeable rock is a rock that lacks porosity and permeability.
- Porosity is the amount or percentage of void spaces in rock.
- Permeability is the inter-connectivity of the pores.
- When a rock is impermeable, it will not allow water to infiltrate.

Answer:
In physics, action is an attribute of the dynamics of a physical system from which the equations of motion of the system can be derived through the principle of stationary action. ... Action has dimensions of energy⋅time or momentum⋅length, and its SI unit is joule-second.
