Answer:
Energy is halved.
Explanation:
Energy and Frequency are directly proportional. If frequency decreases, energy increases. If frequency increases, energy increases. If frequency is halved, energy is also halved.
Answer:
Total pressure = 22.15 atm
Explanation:
Given data:
Total pressure = ?
Volume of container = 7.85 L
Number of moles of N₂ = 4.45 mol
Number of moles of O₂ = 2.45 mol
Temperature = 307 K
Solution:
Pressure of N₂:
PV = nRT
P = nRT/V
P = 4.45 mol ×0.0821 atm.L/mol.K ×307K / 7.85L
P = 112.16 atm.L/7.85 L
P = 14.28 atm
Pressure of O₂:
PV = nRT
P = nRT/V
P = 2.45 mol ×0.0821 atm.L/mol.K ×307K / 7.85L
P = 61.75 atm.L/7.85 L
P = 7.87 atm
Total pressure = P(N₂) + P(O₂)
Total pressure = P( 14.28 atm) + P( 7.87 atm)
Total pressure = 22.15 atm

Hello Gary!
*Sorry if I'm late*
Your answer is going to be 65.
Element A (which is actually Zinc) has the atomic number of 65. (I remember having got memorize this also).
Pretty much the explanation is that the number of patrons is equivalent to the element's atomic number!
Hope this helps!
Have a nice day :D
