Answer:
Provide reinforcement for appropriate behavior.
Explanation:
The use of reinforcements by teachers have been effective in eliminating overt behaviors by students. Different types of “reinforcers” have been tried out and deemed successful in changing student behavior. Nodding of head, clapping and smiling (which express approvals of actions) are some of the social reinforcers, pre-planned by teachers to help instill acceptable deeds.
In some other cases, other powerfully motivating reinforcers have been for the student to select class activities they wish to participate in and the preferred classmate they hope to have in such activities.
Answer: The number of gram of ammonia gas () contained in the a 3.0L vessel at 305 K with a pressure of 1.50 atm is 3.048 g.
Explanation:
Given: Volume = 3.0 L
Temperature = 305 K
Pressure = 1.50 atm
Formula used to calculate the number of moles is as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.
It is known that moles is the mass of substance divided by its molar mass.
Hence, mass of ammonia gas (molar mass = 17.03 g/mol) is as follows.
Thus, we can conclude that the number of gram of ammonia gas () contained in the a 3.0L vessel at 305 K with a pressure of 1.50 atm is 3.048 g.
