It would have to be 40.0 only because it wouldn’t add up
Electrons are electrochemically negatively charged particles that move random around the nucleus. They have a relatively small mass compared to Protons and Neutrons. They are found in electron clouds that surround the nucleus and their movement and properties provide for the bonding characteristics of each atom.
Answer:
The total work is 4957.45J
Explanation:
For an ideal gas, at constant temperature the definition of work (W) is
where P is the pressure, V the volume, n the moles number, T the temperature and R the gas constant.
To solve the problem is necessary to replace the two steps in the equation
Stape 1: n = 1 mol, R = 0.082atm.L/K.mol, T = 77ºC = 350K, Pi = 5.50atm and Pf = 2.43atm.
Stape 2: n = 1 mol, R = 0.082atm.L/K.mol, T = 77ºC = 350K, Pi = 2.43atm and Pf = 1.00atm.
The total work is the sum of the two steps
Answer:
Check the answers in the explanation
Explanation:
The following are the answers
(1) if the solution is colourless : The answer is B Cr207
(2) If the solution gives no apparent reaction with dilute hydrochloric acid, : The answer is A CO3
(3) if No odour can be detected when a sample of the solution is added drop by drop to a warm solution of sodium hydroxide : The answer is C NH4
(4) If No precipitate is formed when a dilute solution of H2SO4 is added to a sample of the solution : The answer is D ba
