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
Answer:
51.2g of CO2
Explanation:
The first step is to balance the reaction equation as shown in the solution attached. Without balancing the reaction equation, one can never obtain the correct answer! Then obtain the masses of octane reacted and carbon dioxide produced from the stoichiometric equation. After that, we now compare it with what is given as shown in the image attached.
Answer: D
Explanation: fungi kingdom is Hetrotropiv and is unicellular
Answer:
Either Carnivores or Heterotrophic.
Explanation:
Carnivorous organisms are the more obvious answers in this, but if you want a bit of pizazz, throw in Heterotrophic Fungi.
