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 
Velocity = 15 m/s
90/2 = 45 m
45/3 (seconds to reach) = 15 m
Conductive when liquid - ions are charged particles, but ionic compounds can only conduct electricity if their ions are free to move. So ionic compounds do not conduct electricity when they are solid, but they do conduct electricity when they are dissolved in water or when they are melted.
Trail mix becasue it is a mixture of different things
Answer:
i think its false because heat is defined as the sum of kinetic enegry present in the molecules of substances.
