Answer:Answer:

For 1: The correct answer is Model 1, 2, and 4.

For 2: The correct answer is Option 1.

Explanation:

For 1:

An element has 3 subatomic particles: electrons (E), neutrons (N) and protons (P).

Atomic number is defined as the number of protons or number of electrons.

Atoms having same number of protons are same. From the given models, Model 1, 2 and 4 have 2 protons with different neutrons. Hence, these models belong to same element.

For 2:

A compound is defined as a substance in which two or more types of elements combine in a fixed ratio. For Example:  is a compound made out of atoms of carbon and oxygen.

Hence, the correct answer is Option 2.

1. A rock sample has a mass of 16 grams:
Morgarella [4.7K]

Answer:

(3) 4 cm' and 2.0 g/cm3

Explanation:

Given:

volume= V= 8 cm³

mass= m= 16 g

The density is the mass per volume of a substance, so the density of the rock is:

density= d= 16 g/8 cm³= 2 g/cm³

When we cut the rock in half, we have a half volume and a half mass:

V= 8 cm³/2= 4 cm³

m= 16 g/2= 8 g

But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:

d = m/V= 8 g/4 cm³= 2 g/cm³
