A would be correct. Hope i helped.
Answer:
n = 2 mol
Explanation:
Given data:
Pressure = standard = 1 atm
Temperature = standard = 273.15 K
Volume = 44.8 L
Number of moles = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
1 atm × 44.8 L = n × 0.0821 atm.L/ mol.K × 273.15 K
44.8 atm.L = n × 22.43 atm.L/ mol
n = 44.8 atm.L / 22.43 atm.L/ mol
n = 2 mol
Answer:
the time required for one half of a sample of a radioisotope to decay
Answer:
By presenting the results in a poster session.
Explanation:
Several scientists from different countries are asked to examine the results of an experiment before a journal will print it.
The answer is A because energy is always required to break a bond which is bound energy and and energy is also required to break a bound to make another or new energy
