It depends on the compound.
Answer: The partial pressure of is 0.35 atm.
Explanation:
Given: Total pressure = 0.98 atm
Partial pressure of = 0.48 atm
Partial pressure of Ar = 0.15 atm
Partial pressure of = ?
Total pressure is the sum of partial pressure of each component present in a mixture of gases.
Hence, partial pressure of is calculated as follows.
Total pressure =
Substitute the values into above formula as follows.
Thus, we can conclude that the partial pressure of is 0.35 atm.
Answer:between 25 and 40 degrees Fahrenheit
Explanation:
Heat pumps do not operate as efficiently when temperatures drop to between 25 and 40 degrees Fahrenheit for most systems. A heat pump works best when the temperature is above 40. Once outdoor temperatures drop to 40 degrees, heat pumps start losing efficiency, and they consume more energy to do their jobs.
Answer: 8.57 ml of KOH is required to reach the equivalence point.
Explanation:
To calculate the volume of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is KOH.
We are given:
Putting values in above equation, we get:
Thus 8.57 ml of KOH is required to reach the equivalence point.
Answer:
The temperature over the land has become higher than the temperature over the water.
Explanation:
The air over the warmer land becomes heated and rises, and the cooler and denser air over the water moves in to take its place.
A is wrong. Clouds move where the upper air currents take them.
B is wrong. The highest air temperature of the day may still be lower than that of the air over the water.
D is wrong. Higher air temperature over the water would create a land breeze.
