They all describe some type of movement.
Answer:
Explanation:
Hello,
At first, the answer is wrong, consider the following procedure:
- the pKs, leads to a Ks of:
- now, stating the equilibrium for the calcium sulfate (whereas x is the change during the equilibrium):
- x becomes the concentration of calcium ions and one of the contributions for the total concentration of sulfate ions, thus:
- finally, since the sodium sulfate is totally dissolved, we just simply add its concentration (equal to the sulfate ions yielded by itself) to the outgoing sulfate concentration from the calcium sulfate:

Answer:
a) 4480L
b) 56L
Explanation:
To answer this question you need to know that Cl2 molecular weight is 71 g/mol and gas volume at NTP is 22.4 L/mol.
a) 14.2 kg of Cl2 in moles will be: 14.2 kg * (1000g/kg) / ( 71g/mol)= 200 mol
The volume of 200 mol of gas in NTP will be: 200 mol * 22.4L/mol= 4480L
b) every mol is made of 6.02 * 10²³ molecules. Then the volume of the gas will be: (15,055×10²³ molecule) / (6.02 * 10²³ molecules/mol) * 22.4 L/mol= 56L
