At 0 °C, some amount of energy is required to change 1 kg of water from a solid into a liquid. If you had a 2 kg piece of ice, w

hat effect would this have on the amount of thermal energy required to change the water from a solid to a liquid? O It would require more energy to change solid water into liquid water because there are more molecules in this larger piece of ice. It would still require the same amount of energy to change solid water into liquid water because the entire piece of ice would still gain the same amount of energy in each case.​

Recall all the models you described in task 1. Think about the results each model would predict for ruthefords experiment. Which
maxonik [38]

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.

In terms of valence electrons, explain why metals form positive ions.
diamong [38]

Answer:

Explanation:

Metal elements form positively charged ions called cations because they are located on the left side of the periodic table These elements all have valence electrons in an s orbital. These electrons are relatively easy for the atom to lose to achieve a stable octet of electrons in its outermost energy shell.
