An unknown substance dissolves in water but separates and floats in oil.
Answer:
Any polar substance
Explanation:
We know that non polar substances wont dissolve in water because they do not react properly with water molecules, any polar substance would dissolve in water and float in oil.
An unknown substance dissolves in water but separates and floats in oil is any polar substance.
What are polar substances?Polar substance are defined as those whose bonding with atoms like nitrogen, oxygen, or sulfur has resulted in discrete positive and negative charge areas.
It can also be defined as an electrical pole is typically created when a molecule has more positive charges on one end than negative charges on the other, forming an electrical pole.
Non polar substances are defined as a molecule that lacks charges at the ends because its electrons are evenly distributed and those that cancel one another out symmetrically.
It is can also be defined as in covalent compounds, there is no change in electronegativity.
Thus, an unknown substance dissolves in water but separates and floats in oil is any polar substance.

Answer:
[tex]\boxed {\boxed {\sf 600 \ kg/m^3}}[/tex]
Explanation:
We are asked to find the density of a bowling ball. The density of an object is its mass per unit volume. It is calculated by dividing the mass by the volume.
[tex]\rho= \frac{m}{v}[/tex]
The mass of the bowling ball is 3.0 kilograms and the volume is 0.0050 cubic meters.
m= 3.0 kg v= 0.0050 m³Substitute the values into the formula.
[tex]\rho= \frac{3.0 \ kg}{0.0050 \ m^3}[/tex]
Divide.
[tex]\rho= 600 \ kg/m^3[/tex]
The density of the bowling ball is 600 kilograms per cubic meter.
Two containers of gas have the same volume, temperature and pressure. One container has a sample of oxygen gas having a mass of 3.95g. The other container has a gas with a mass of 2.99g. Determine the molar mass of the gas in the second container.
Answer:
24.3
Explanation:
Two containers of gas have the same volume, temperature and pressure. One container has a sample of oxygen gas having a mass of 3.95g. The other container has a gas with a mass of 2.99g. Determine the molar mass of the gas in the second container.
O2 has a molar mass of 16 X 2 =32
the number of moles for O2 is the weight divided by the molar mass or, but since the two container have the same P,V, AND T they have the same number of moles since
PV =nRT
SO
the weight of the gas in the second container divided by its molar mass =
0.123
or
2.99/? = 0.123
so
? = 2.99/o.123 = 24.3

Part D: Bohr’s Atomic Model Question 1 Using what you can recall from this unit, write one or two short paragraphs describing Niels Bohr’s atomic model. If needed, you may search the Internet for descriptions of the model.
Answer:
The Bohr Model is a planetary model in which the negatively-charged electrons orbit a small, positively-charged nucleus similar to the planets orbiting the Sun (except that the orbits are not planar). The gravitational force of the solar system is mathematically akin to the Coulomb (electrical) force between the positively-charged nucleus and the negatively-charged electrons.
Main Points of the Bohr Model
Electrons orbit the nucleus in orbits that have a set size and energy.
The energy of the orbit is related to its size. The lowest energy is found in the smallest orbit.
Radiation is absorbed or emitted when an electron moves from one orbit to another.
Have a great day friend! :D
A small positive charges nucleus is encircled by revolving negatively charged electrons in fixed orbits, according to the Bohr Atomic model.
What are the drawbacks of Bohr’s Atomic Model?The atom is basically depicted in the Bohr model as a central nucleus containing protons along with neutrons, with electrons in circular orbitals at various distances from the nucleus.
These orbits combine to form electron shells or energy levels, which allow you to see how many electrons are in each shell.
He concluded that electrons have more energy when they are located away from the nucleus, whereas electrons have less energy when they are located near the nucleus.
He was unable to explain the specifics of the Hydrogen and Helium atomic spectrums.
He did not explain how spectral lines split in the presence of a magnetic field. He did not explain the intensity of spectral lines.
Thus, these can be concluded regarding the Bohor's atomic model.

B it involves the losing and gaining of electrons
Cit involves the sharing of electrons
Dit involves the moving of electrons between energy levels
Answer:
C. it involves the sharing of electrons
Explanation:
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

Vinegar is an ingredient commonly used by chefs. Scientists also use it as well, although they call it acetic acid. When vinegar is in its liquid or solid (frozen) states, it has a fixed volume. But when vinegar is in its gas state, it takes up the entire volume of whatever container it is in. This is why you can smell an open bottle of vinegar the minute you walk into a kitchen, even though you cannot actually see the gas particles!
Which statement best explains why the volume of vinegar gas is changeable as opposed to the fixed volume of its solid and liquid states?
A. Gas particles are always at a higher pressure than solids and liquids.
B. Gas particles are always at a higher temperature than solids and liquids.
C. Gas particles are spaced far apart and can move freely.
D. Gas particles stay close together but can move around each other.
Answer: C
Explanation: Because gas particles are free to move fast where as liquid can move a little but solid cant so it would be C
