Answer : The volume of container will be 44.8 L
Explanation :
At STP condition,
The temperature and pressure are 273 K and 1 atm respectively.
As we know that at STP, 1 mole of substance occupies 22.4 L volume of gas.
As per question,
1 mole of nitrogen gas occupies 22.4 L volume
and,
1 mole of neon gas also occupies 22.4 L volume
Thus, total volume will be:
Total volume of container = 22.4 + 22.4 = 44.8 L
Hence, the volume of container will be 44.8 L
Answer: 3.72 M
Explanation:
Expression for rate law for first order kinetics is given by:

where,
k = rate constant = 
t = age of sample = 15.0 minutes
a = let initial amount of the reactant = 10.0 M
a - x = amount left after decay process = ?




The concentration of
in a solution after 15.0 minutes have passed is 3.72 M
To convert 3 mol H2O to grams, just multiply by the molar mass of H2O.
<span>3 mol H2O * 18 g H2O / 1 mol H2O = 54 g H2O
Hope this helped.</span>
1.53 moles of Fe is your solution hope it helps!
They go through radioactive decay because when atoms are unstable by going through it they are emitting radiation in natural process and they gain stability by losing energy.
