write the equation for the combined gas law using temperature in degree Celsius. explain why the Kelvin scale is convenient
Answers
Answer:
Explanation:
Combine Gas law is a combination of three gas laws which are Boyle's Law, Charles' Law, and Gay-Lussac's Law.
Combine gas law states that the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant.
Hence the equation becomes:
where P = pressure,
V = volume,
T = absolute temperature,
k = constant.
Now we know that Kelvin = °Celsius + 273
For all gas law problems it is necessary to work in the Kelvin scale because temperature is in the denominator in the combined gas laws (P/T, V/T and PV/T) and can be derived in the ideal gas law to the denominator (PV/RT) . If we measured temperature in Celsius we could have a value of zero degrees Celsius and this would solve as no solution, as you cannot have zero in the denominator.
However, if we reached zero in the Kelvin scale this would be absolute zero and all matter would stop and therefore there would be no gas laws to worry about.

Answer : The correct option is, hydration
Explanation :
Hydration : It is a process in which the ion or substance combines with water and kept in the solution. In the hydration process the solvent is water molecule.
For example : When the sodium chloride is dissolved in the water then the positive sodium ion get surrounded by the water molecule through their oxygen ends and the negative chloride ion get surrounded by the water molecule through their hydrogen ends.
Dissociation : It is a process in which the compound splits or dissociates into to two or more smaller ions, atoms or particles.
Electrolyte : it is a process in which the a molecule is completely dissociates into their respective ions in the aqueous solution.
Ionization : It is a process in which a molecule acquire a positive or negative charged by the gaining or losing electrons.
Hence, the correct option is, hydration.

If an object is flat and it falls it will go against the air (Air-Resistance) when falling down, which it will make the block go slower then a sphere which has no sides and will fall faster then the square or Block because there isn't a flat side it wont go against the air ( Air-Resistance).

The answer option which lists celestial bodies in order, from closest to furthest from the Earth is: A) moon, sun, near edge of milky way, center of milky way.
A planet can be defined as a large celestial body that has sufficient mass to allow for self-gravity and make it assume a nearly circular shape (hydrostatic equilibrium).
Basically, a planet revolves in an orbit around the Sun in the solar system and has a cleared neighborhood.
In Science, planets are broadly grouped into two (2) main types and these are;
I. Inner planets: these planets are closest to the Sun and comprises Mars, Mercury, Venus, and Earth.
II. Outer planets: these planets are mainly located beyond the asteroid belt and includes Uranus, Jupiter, Neptune, and Saturn, from left to right of the solar system.
On the other hand, a list of the celestial bodies in order, from closest to furthest from planet Earth are:
- Moon: its distance from planet Earth is about 405,696 kilometers.
- Sun: its distance from planet Earth is about 149,597,870 kilometers.
- Near edge of milky way: its distance from planet Earth is about 1,000,000,000,000,000,000 kilometers.
- Center of milky way: is the farthest from planet Earth.

The moon is right next to Earth.
Earth orbits around the sun.
Our solar system is at the edge of the Milky Way. So the edge of the Milky Way would be nearer than the center.

Explanation:
(2) different physical properties and the same chemical properties
(3) the same physical properties and different chemical properties
(4) the same physical properties and the same chemical properties
Answers
Justification:
1) Any chemical compound has its unique physical and chemical properties.
2) Although formed by the same elements, N and O, NO₂ and N₂O are different compounds, so each will have its proper physical and chemical properties.
3) The union of the atoms by chemical bonds confere the properties to a matter, so being the bonds in N₂O different to the bonds in N₂O means they are different compounds.
