Answer:
FeS
Explanation:
The reason why their is no subscripts is because as put in the question, the charges are equivalent. As you can see, +2 and -2 equal each other out.
Note: S has a charge of -2, not +2. (Look at oxidation rules.)
Answer:
The partial pressure of the gas produced by the reaction is 0.9187 atm
Explanation:
Given;
vapor pressure of water, 
= 0.0313 atm
measured atmospheric pressure, 
= 0.950 atm
partial pressure of the gas produced by the reaction = ?
According to Dalton's law of partial pressure; total pressure is equal to sum of partial pressure of water vapor and gas produced.
= 
= 0.95 - 0.0313
= 0.9187 atm
Therefore, the partial pressure of the gas produced by the reaction is 0.9187 atm
The age of the remnants is calculated as 3807 years.
<h3>What is the half life?</h3>
The half life is the time taken for only half of the number of the radioactive atoms to remain.
Half life of carbon - 14 = 5730 years.
Initial count rate = 8.0 counts per minute per gram
Count rate at time t = 12.7 counts per minute per gram of carbon
Since;
0.693/t1/2 =2.303/t log (N/No)
0.693/5730 = 2.303/t log (12.7/8)
1.21 * 10^-4 = 2.303/t * 0.2
t = 2.303 * 0.2/1.21 * 10^-4
t = 0.4606/1.21 * 10^-4
t = 3807 years
