"a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction."
a reaction that is caused by chemicals
Answer:
1.8 moles
Explanation:
Number of moles = ?
Pressure = 15.4 atm
Volume = 2.92L
Temperature = 32°C = (32 + 273.15)K = 305.15K
From ideal gas equation,
PV = nRT
P = pressure of the ideal gas
V = volume in which the gas occupies
n = number of moles
R = ideal gas constant = 0.082J/mol.K
T = temperature of the gas
PV = nRT
n = PV / RT
n = (15.4 * 2.92) / (0.082 * 305.15)
n = (44.968 / 25.0223)
n = 1.797 moles = 1.8 moles
Number of moles of the gas is 1.8 moles

<u>Answer:</u> The concentration of
ions is 0.10 M and that of
ions is 0.30 M
<u>Explanation:</u>
We are given:
Concentration of
= 0.10 M
The chemical equation for the ionization of aluminium bromide follows:
![AlBr_3\rightarrow Al^{3+}+3Br^-](https://tex.z-dn.net/?f=AlBr_3%5Crightarrow%20Al%5E%7B3%2B%7D%2B3Br%5E-)
1 mole of aluminium bromide produces 1 mole of aluminium ions and 3 moles of bromide ions
So, concentration of aluminium ions = 0.10 M
Concentration of bromide ions = ![[(3\times 0.1)]=0.3M](https://tex.z-dn.net/?f=%5B%283%5Ctimes%200.1%29%5D%3D0.3M)
Hence, the concentration of
ions is 0.10 M and that of
ions is 0.30 M
