Answer:
postpurchase dissonance
Explanation:
The feeling of the buyer after the acquisition of the product can influence the repetition of sales and what he tells others about the product purchased.
A phenomenon that usually occurs after the purchase of the product or service is that of: cognitive dissonance.
Each of the alternatives that the consumer has considered has advantages and limitations, that is, when the purchase decision is finally made, the selected product has certain drawbacks while each of the rejected alternatives has some attractive characteristics.
The negative aspects of the article that is selected together with the positive qualities of the products that are rejected create cognitive dissonance in the consumer.
This cognitive dissonance may vary due to the behavior of the following variables:
- The nominal and real value (money) of the purchase
.
- Rejection of similarity of selected and rejected articles.
- The relative importance of the decision.
Answer:
Earth’s climate is changing rapidly. We know this from billions of observations, documented in thousands of journal papers and texts and summarized every few years by the United Nations’ Intergovernmental Panel on Climate Change. The primary cause of that change is the release of carbon dioxide from burning coal, oil and natural gas.
One of the goals of the international Paris Agreement on climate change is to limit the increase of the global surface average air temperature to 2 degrees Celsius, compared to preindustrial times. There is a further commitment to strive to limit the increase to 1.5℃.
Earth has already, essentially, reached the 1℃ threshold. Despite the avoidance of millions of tons of carbon dioxide emissions through use of renewable energy, increased efficiency and conservation efforts, the rate of increase of carbon dioxide in the atmosphere remains high.
International plans on how to deal with climate change are painstakingly difficult to cobble together and take decades to work out. Most climate scientists and negotiators were dismayed by President Trump’s announcement that the U.S. will withdraw from the Paris Agreement.
But setting aside the politics, how much warming are we already locked into? If we stop emitting greenhouse gases right now, why would the temperature continue to rise?
Basics of carbon and climate
The carbon dioxide that accumulates in the atmosphere insulates the surface of the Earth. It’s like a warming blanket that holds in heat. This energy increases the average temperature of the Earth’s surface, heats the oceans and melts polar ice. As consequences, sea level rises and weather changes.

Answer:
i. n = 5
ii. ΔE = 7.61 × 
KJ/mole
Explanation:
1. ΔE = (1/λ) = -2.178 × 
(
- 
)
(1/434 × 
) = -2.178 × (
)
⇒ 434 × = (1/-2.178 × )
But, 
= 2
434 × = (1/2.178 × )
434 × × 2.178 × = 
⇒ 
= 5
Therefore, the initial energy level where transition occurred is from 5.
2. ΔE = hf
= (hc) ÷ λ
= (6.626 × 10−34 × 3.0 × 
) ÷ (434 × )
= (1.9878 × 
) ÷ (434 × )
= 4.58 × 
J
= 4.58 × 
KJ
But 1 mole = 6.02×
, then;
energy in KJ/mole = (4.58 × KJ) ÷ (6.02×)
= 7.61 × KJ/mole
Explanation:
Percentage composition tells you the percentage of each element present in a compound or molecule. This allows you to work out the number of atoms of each element present in the molecule. Percent composition is important because it allows us to determine the percentage of each element that makes up a specific compound. Percent composition is important because it allows us to determine the percentage of each element that makes up a specific compound.
