After a good long amount of research, I found that the scientific answer to this question would be a big ol’ dink
Answer: The rate constant for the reaction is 
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample = 559 min
a = let initial amount of the reactant = 
a - x = amount left after decay process = 
The rate constant for the reaction is
ΔΗ= -115.6 kJ/mol
H2 has a Mr of 2, so as mol=mass/mr we can work out that there are 4 moles of H reacting
Therefore we multiply -115.6 by 4 = -462.4
The mineral is Iron Sulphide. It is not a mixture, but a compound. A mixture is when two substances are together, but not chemically bonded. For example, if I add food colouring to water, I have made a mixture because the food colouring has not chemically bonded to the water. If I react Iron with Suphur, the resulting substance is a compound. The resulting mineral will not burn or be magnetic because the compound has different properties to the elements themselves. For example, chlorine gas is toxic and sodium reacts violently with water, but sodium chloride is table salt, nor toxic nor explosive.
Hope this helps
Answer:
The mass of 0.100 mole of neon is 2.018 grams.
Explanation:
As we know the formula to find mass:
Number of moles = Mass/ Molar mass
0.100 = Mass/ 20.17
0.100 x 20.17 = Mass
Mass=2.018 grams.
