How to separate these pure substance?if it is not possible, please write cannot be separate
Oxgen
Water
Gold
Carbon Dioxide
Carbon
Answer:
Oxgen- cannot be separated
Water - chemical change
Gold - cannot be separated
Carbon Dioxide - chemical change
Carbon - cannot be separated
Explanation:
A pure substance, which can either be an element or a compound, contains only one type of such element or compound. In opposition to a mixture, pure substances cannot be separated by physical means.
- Elements as a pure substance cannot be separated because it contains only one type of atom. However, compounds contain two or more types of atoms, and hence, can only be separated into its individual atoms via chemical means.
In this question, oxygen (O2), Gold (Au) and carbon (C) are all elements and hence cannot be separated. Carbon dioxide (CO2) and water (H2O) are compounds because they contain two different atoms respectively, hence, can be separated into individual atoms.

A rock mass is 100g. Determine the density of the rock if it has a volume of 20cm3.
Answer:
The answer is 5.0 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 100 g
volume = 20 cm³
We have
[tex]density = \frac{100}{20} = \frac{10}{2} \\ [/tex]
We have the final answer as
5.0 g/cm³Hope this helps you

Which statement best explains why the air pressure is greater at the poles than at the equator
Answer:
At the equator, the altitude is lower, and also because of the direct heating of sun rays on the surface, the temperature is much higher than at the poles. This makes the air near the surface hot and lighter and hence it rises up which results in lower air pressure.

How many atoms are in the following formula?
3Al2O3
Answer:
15 atoms total
Explanation:
2 Al atoms + 3 O atoms = 5 Al2O3 atoms
5 Al2O3 atoms * 3 = 15
another way to do it is:
2 Al atoms * 3 = 6 Al atoms
3 O atoms * 3 = 9 O atoms
6+9 =15 atoms total
The number of atoms in the given 3Al₂O₃ is 15 atoms.
What are atoms?Atoms are the smallest unit of every matter. It contains charged particles present inside the atoms. They are electrons, protons, and neutrons. Atoms are of four types, description, isotopes, radioactive, and ions.
These atoms are the ions, that are charged, and the charged ions make bonds with each other to form compounds. Aluminum oxide is a compound that is formed by combining aluminum and oxygen atoms.
The compound is 3Al₂O₃
This means there are three moles of aluminum, and three moles of oxygen.
2 Al atoms + 3 O atoms = 5 Al₂O₃ atoms
5 Al₂O₃ atoms x 3 = 15
The elaborative way is:
2 Al atoms x 3 = 6 Al atoms
3 O atoms x 3 = 9 O atoms
6 + 9 =15 atoms total
Thus, the number of atoms is 15 atoms.

How much space does 2 x 10^22 atoms of copper take up?
Answer:
2.35mL
Explanation:
The amount of space a substance holds is its volume.
Density = mass (g) /volume (L)
Where;
mole = mass/molar mass
Since 1 mol of Cu contains 6.022 × 10^22 atoms.
There are 2 x 10^22/6.022 × 10^22 moles in 2 x 10^22 atoms of copper
2 x 10^22/6.022 × 10^22
2/6.022 × 10^(22-22)
0.332 × 10^0
0.332mol
Mole = mass/molar mass
0.332 = mass/63.5
mass = 63.5 × 0.332
mass = 21.08g
Density = mass/volume
Density of copper (Cu) is 8.96 g/cm³
8.96 = 21.08/v
V = 21.08/8.96
V = 2.35mL or cm³

If a p-wave arrives at 2:10:00 and the s-wave arrives at 2:15:20, how many kilometers from the epicenter is a location?
Answer:
2.67 x 10⁷km
Explanation:
Given parameters:
Time of arrival of p-waves = 2: 10: 00
Time of arrival of s-waves = 2: 15: 20
Unknown:
Distance of wave from epicenter = ?
Solution:
To find the distance of the wave from the epicenter;
Distance = 3 x 10⁸ x time interval
Time interval = Time of arrival of p-waves - Time of arrival of s-waves
= 2: 10: 00 - 2: 15: 20
= 5min 20s
= 320s
Now, we need to convert the time to hrs;
3600s = 1hr
320s = [tex]\frac{320}{3600}[/tex] = [tex]\frac{4}{45}[/tex]hr
So,
Distance = 3 x 10⁸ x [tex]\frac{4}{45}[/tex] = 2.67 x 10⁷km
