Answer: 296 grams/cm^3 (3 sig figs)
Explanation: Divide the mass by the volume to get grams/cm^3.
mass=35g
density=5 g/cm3
what is the volume?
[tex]\large \mathfrak{Solution : }[/tex]
given values :
mass = 35 g
density = 5 g/cm³
we know that :
[tex] \boxed{density = \dfrac{mass}{volume} }[/tex][tex]5 = \dfrac{35}{vol} [/tex][tex]vol = \dfrac{35}{5} [/tex][tex]volume = 7 \: cm {}^{3} \: or \: 7 \: litres[/tex]Need help please

The volume of a brick is 52 cubic inches. Which choice best describes its volume?
Answer:
I think he was right but not explaining
Explanation:
I think it is C cause.... the volume of a material is the amount of matter that matterial can hold. it should the the amount of space the whole material takes up.
so C is the answer.

Describe what happens to the arrangement and movement of particles when a substance boils.
Answer:
When boiling a substance, the particles obtain more kinetic and potential energy from the heat being delivered. The kinetic energy means that the particles starts moving more intensely, and the potential energy means that the particles start to move away further from each other, which means the substance expands in volume.
Explanation:
When a liquid is heated, the particles gain energy and begin to move faster and faster, expanding the liquid. As the liquid warms, the most energetic particles at the surface escape as vapor from the surface.
What are particles?A particle is a small localized object to which several physical or chemical properties, such as volume, density, or mass, can be assigned in the physical sciences.
Atoms are small units of matter that contain a number of particles known as subatomic particles. The term particle, on the other hand, refers to any small object.
As a result, the primary distinction between atoms and particles is that atoms are small units composed of multiple particles, whereas particles are minute portions of matter.
When a fluid is subjected to heat, the particles acquire energy and start moving extremely fast, causing the liquid to expand.
The much more energetic particles at the exterior getaway as vapor phase from the surface as the liquid warms.
Thus, the arrangement and movement of the particles gets disturbed when a substance is boiled, and it gets escaped as vapor.

Oxygen has an atomic number of 8. Which of the following could form the nucleus of an atom of oxygen?
6 protons and 8 neutrons.
4 protons and 4 neutrons. 6 protons and 2 neutrons. 8 protons and 10 neutrons.
Answer:
Answer: 8 protons and 8 neutrons
Explanation:
The mass number of oxygen is 16
Atomic number is 8
but proton number = atomic number = 8 protons
[tex]neutrons = mass \: number - atomic \: number \\ [/tex]
neutrons = 16 - 8 = 8 neutrons.
The nucleus of an atom of oxygen typically contains 8 protons and 8 neutrons specifically. So, none of the above options is correct.
What is the formula for calculating the atomic number?The atomic number may be defined as the number of a chemical element in the periodic table through which the elements are arranged in order of increasing the number of protons in the nucleus.
The atomic number of an element = The number of protons in the nucleus of an atom.
Now, according to the question,
If Oxygen has an atomic number of 8, that means the number of protons = 8.
The number of neutrons can be calculated as follows:
Neutrons = mass number - the atomic number.
= 16 - 8 = 8 neutrons.
Therefore, the nucleus of an atom of oxygen typically contains 8 protons and 8 neutrons specifically. So, none of the above options is correct.

how can fossil records be useful to determine the relative ages of rock layers and other fossils?
Answer:
If the same index fossil is found in different areas, the strata in each area were likely deposited at the same time. Thus, the principle of faunal succession makes it possible to determine the relative age of unknown fossils and correlate fossil sites across large discontinuous areas.
is energy absorbed or released to separate the atoms in water molecules
Answer:
First of all, Energy is released when water molecules bond.
Explanation:
When a bond is formed its stability increases from their respective atoms. So energy is released but when we are breaking a bond we are changing a compound to a lower energy state to higher energy state it's stability decreases and requires a bit of extra energy higher stability of bond higher energy required to break it…
