Question 19

Which of the following statements correctly compares the Plum pudding model and the Bohr model of the atom?

Accepted Answer

The Plum pudding model describes electrons embedded in a positive sphere, while the Bohr model describes electrons orbiting a nucleus.

Answer

Both models describe the atom as having a central nucleus.

Which of the following statements is true about the Chemistry Laws: The law of conservation of Mass, The Law of Definite Proportions, The Law of Multiple Proportions?

Accepted Answer

All of the above statements are true.

Answer

The law of conservation of Mass states that mass is neither created nor destroyed in a chemical reaction.

Answer

The Law of Definite Proportions states that a chemical compound always contains exactly the same proportion of elements by mass.

Answer

The Law of Multiple Proportions states that if two elements form more than one compound, the masses of one element that combine with a fixed mass of the other are in the ratio of small whole numbers.
