Answer:
The total pressure after one half is 6.375 atm.
Explanation:
The initial pressure of product is increases while the pressure of reactant would decrease.
Balanced chemical equation:
2N₂O → 2N₂ + O₂
The pressure of N₂O is 5.10 atm. The change in pressure would be,
N₂O = -2x
N₂ = +2x
O₂ = +x
The total pressure will be
P(total) = P(N₂O) + P(N₂) + P(O₂)
P(total) = ( 5.10 - 2x) + (2x) + (x)
P(total) = 5.10 + x
After one half life:
P(N₂O) = 1/2(5.10) = 5.10 - 2x
x = 5.10 - 1/2(5.10) /2
x = 5.10 - 0.5 (5.10) /2
x = 5.10 - 2.55 / 2
x = 2.55 /2 = 1.275 atm
Thus the total pressure will be,
P(total) = 5.10 + x
P(total) = 5.10 + 1.275
P(total) = 6.375 atm
Each kind of scientist is matched with an aspect of the hot spring he or she is most likely to study as follows:
- <u>Geologist:</u> rocks around and under the hot spring.
- <u>Ecologist:</u> relationships between organisms and the hot spring.
- <u>Sociologist:</u> human behavior around the hot spring.
- <u>Meteorologist:</u> atmosphere and weather around the hot spring.
<h3>What is a scientific observation?</h3>
A scientific observation can be defined as an active acquisition of knowledge (information) through one of the sense organs, while using scientific tools and instruments.
<h3>The types of
scientific observation.</h3>
In Science, there are two main types of scientific observation and these include the following:
<h3>What is a
hot spring?</h3>
A hot spring can be defined as a natural or an artificially-induced phenomena in which very hot groundwater flows out from the Earth's crust due to the heat present in the geosphere.
In this exercise, you're required to match each kind of scientist with an aspect of the hot spring he or she is most likely to study as follows:
- <u>Geologist:</u> rocks around and under the hot spring.
- <u>Ecologist:</u> relationships between organisms and the hot spring.
- <u>Sociologist:</u> human behavior around the hot spring.
- <u>Meteorologist:</u> atmosphere and weather around the hot spring.

Answer:
Molecules
Explanation:
Electromagnetic waves are not like sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air, solid objects and even space.
