1. The equation representing the equation is ~
[tex] \mathrm{Na + Cl\rightarrow NaCl}[/tex]
The given reaction is a redox reaction because there's a transfer of electron from Sodium (Na) to chlorine (Cl)
where sodium is oxidized (due to loss of electron) and chlorine get reduced (due to gain of electron).
2. Sodium is a highly reactive element which belongs to the 1st group of periodic table, hence it can catch fire if it is kept free in atmosphere. so in order to prevent that it is stored in kerosene oil, which doesn't let Sodium come in contact with air .

Suppose a high-flying jumbo jet with a mass of 45,000 kg cruises at constant velocity when the thrust of its engine is a constant 80,000 N. What is the acceleration of the jet?
Answers
Answer:
1.78 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass
From the question we have
[tex]a = \frac{80000}{45000} = \frac{80}{45} \\ = 1.77777...[/tex]
We have the final answer as
1.78 m/s²Hope this helps you

why do garden manure and compost fertilize the soil
Answers
gardens arent real the government is lying the world is a simulation
As the soil absorbs manure, nutrients are released. This enriches the soil, which in turn helps the plants. The most important benefit of using manure in the garden is its ability to condition the soil For instance, mixing manure with sandy soils helps to retain moisture levels.
If you increase the force on an object, its acceleration increases. True or false
Answers
Answer:
true
Explanation:
from Newton's second law of motion ,we can understand that acceleration of a body is directly proportional to the force applied on it and inversely proportional to its mass ,so as the force applied increase,the acceleration also increases

NO2 is a reddish brown color while N2O4 is colorless. Based on this information only, which type of spectroscopy would be a good choice to determine the identity of an unknown sample that contains either
NO2 or N2O4?
Answers
Spectroscopy is is an area of science that deals with interaction of matter and the electromagnetic spectrum. Colorimetry can distinguish between a colorless and a colored substance.
The type of spectroscopy that would be a good choice to determine the identity of an unknown sample is a type of spectroscopy that deal with the interaction of visible light with matter.
A type of spectroscopy that deals with interaction of visible light with matter is colorimetry. Colorimetry can measure the concentration of a substance as a function of the amount of light that is absorbed by the substance.
Since NO2 has a reddish brown color, its concentration can be measured using colorimetry. The concentration of N2O4 can not be measured using colorimetry because it is colorless.

14. An atom has 10 protons, 8 electrons, and 7 neutrons. What is the charge of the
atom and what type of ion is it?
Answers
The charge on an atom = # of protons - # of electrons
= 10 - 8
= +2
∴ the atom is a CATION (ion) of +2 charge.

6) Which of the following would travel the farthest in column chromatography?
a. CH3CH2CH2COOH
b. C6H6
c. CH3OH
d. C8H18
Answers
The answer would be C8H18, or octane. Column chromatography is a separation technique that works off of polarity. The stationary phase, in column chromatography, are non-modified silica gels. Silica gels are normally polar. This means the solvent that will elute first are non-polar molecules...then polar molecules. The polar silica gels have a stronger interaction with polar molecules like CH3OH, and therefore will lag the solvent. Additionally, as you decrease the carbons, in hydrocarbons, the molecule becomes more polar. This is not C6H6 isn't the answer and octane is.
C8H18 will travel the farthest in column chromatography.
Chromatography is know as a process of analyzing and purifying organic compounds.There are different forms of chromatography. there is the column chromatography, Gas chromatography etc.
Alkanes are known to be least polar and as such would travel farthest into the mobile phase of the four functional groups. C8H18 belongs to the alkanes family.
