Answer:

Chemical properties, such as combustibility, are generally observed as the identity of a substance changes and one or more new substances form.

Explanation:

Chemical change involves formation of new substances. Therefore, the correct answer is "Chemical properties, such as combustibility, are generally observed as the identity of a substance changes and one or more new substances form."

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.

Answer:

Explanation:

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

Answer:40=6*6(6+5)8x42

Explanation: so yea

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.

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.

Explanation:

Answer:7.229 grams of oxygen is formed by the complete reaction of 35.23 g of metallic sodium with oxygen at 130–200 °C, a process that generates sodium oxide, which in a separate stage absorbs oxygen: 4 Na + O2 → 2 Na2O. The ozone oxidizes the sodium to form sodium peroxide.

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.
