Which of the following bases is the STRONGEST? The base is followed by its Kb.A. C6H5NH2, 4.0 × 10-10 B. NH3, 1.76 × 10-5 C. CH3
Kamila [148]

Answer:

(D) (CH3CH2)2NH

Explanation:

In order to decide which base is strongest we need to calculate its PKb

PKb = -log [Kb]

A large Kb value and small PKb value gives the strongest base

 Compound                   Kb                           PKb      

(A) C6H5NH2 -         4 x 10^-10                      9.349

(B) NH3                     1.76x 10^-5                    4.754

(C) CH3NH2              4.4x 10^-4                     3.357

(D) (CH3CH2)2NH   8.6x 10^-4                     3.066

(E) C5H5N                  1.7x10^-9                      8.77  

Clearly (CH3CH2)2NH is the strongest base.

What is soil? where do the water and nutrients found in the soil come from?
Liono4ka [1.6K]

Answer:

Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life.

We get these from the plants that grow, and the animals that we eat that eat the plants. Most soils have a large supply of nutrients in them, and they get taken up by plants when plants absorb water. Soils need to be healthy to grow large quantities of plants, and animals need plants to grow strong.

The practice of making operations "carbon neutral" is a way to offset whatever damage is being done to the environment due to gr
Marianna [84]

Answer:

True

Explanation:

The greenhouse effect is the process whereby there is radiation from a atmosphere planet and the planet increase the temperature of the planet's surface to a temperature above normal.In this process the Earth's atmosphere becomes thicker with the influence substances such as gases

and the radiation coming from the sun is trapped, then the Earth becomes warmer. Green house effect is seen in global warming.

Carbon neutral can be described as a process of removing huge amount of carbon dioxide from the atmosphere in order to achieve zero carbon neutrality.It is also reffered to as carbon neutrality, and this can be achieved by actions of organizations, businesses and individuals .

Carbon neutral can be achieved in two ways;

: 1.) Maintaining a balance between carbon dioxide emissions and carbon removal by means of the process called carbon offsetting

2 ) the process of removal of carbon dioxide from the atmosphere in order to balance up emissions in another place.

Carbon positive is crucial to increase the positive influence of our daily activities on climate change and our resources.

while reduce the negative effect of our activities and business on evironment.

Therefore, the practice of making operations "carbon neutral" is a way to offset whatever damage is being done to the environment due to greenhouse gas emissions by purchasing credits from "carbon-positive" projects to balance out emissions is true because the harmful gasses that is been released to the atmosphere is balance up by the carbon neutral process hence the reduction in green house effect.
