The two compounds present in unpolluted air are carbon dioxide and water. You may think that carbn dioxide is a greenhouse gas, yes it is and at the same time not. There animals in the earth that produces carbon dioxide into the atmosphere, the carbon dioxide too, is also need for plan respiration.
Unpolluted air contains small amounts of various compounds. Examples include Carbon Dioxide (CO2) which is used in the process of photosynthesis and Argon (Ar) which remains chemically inactive.
Unpolluted air primarily consists of nitrogen and oxygen, but it also contains small amounts of other gaseous compounds. Two of these compounds found in unpolluted air are carbon dioxide (CO2) and argon (Ar). Carbon dioxide (CO2), which is produced by animals during respiration and used by plants during photosynthesis, and argon (Ar), a noble gas, which is chemically inert and does not directly affect the climate or living organisms.

(2) an indicator (4) thermal energy
Given:
8.32 J of heat
from 23.2 degrees C to 30.5 degrees C
heat capacity of aluminum is 0.90 J/g-K
Required:
m in grams
Solution:
H = mCpT
(8.32 J) = m(0.90 J/g-K)(30.5 – 23.2)K
m = 1.27g
Sam would have to purchase 42 cans of dog food each week.
Determine what the question is asking. Write down the relevant information in simple statements. Assign symbols to unknown values that need to be found. Determine how the statements relate to each other mathematically.
To find the answer we can set up an equation : 3 (x) (d)
x = number of cans each dog eats
d = the number of days in a week.
Thus,
Number of Cans to purchase = 3 (2) (7)=42
Therefore, Sam would have to purchase 42 cans of dog food each week.

O High temperatures and location in high latitudes
O Moderate temperatures and location in mid to high latitudes
O Warmer temperatures and location around the equator
Answer: D
Explanation:
Answer: High temperatures and location in high latitudes
Explanation:
Answer:
Option (2)
Explanation:
The water in most of the region is generally pumped out of the ground for the purpose of irrigation. This rate of pumping is much higher than the rate of replenishment. The over-pumping of water leads to the lowering of the water table
About 60 to 70% of the water that is used for irrigation purposes does not reach the crop. It is because the water most of the time gets percolated down into the deeper zones. In addition to this, the water also leaks through the fractures that are associated with the canals and increasing rate of evaporation.
Thus, the correct answer is option (2).
Answer:b never reaches the crop hopefully helps
