Answer:
0.1440M
Explanation:
Let''s bring out the parameters we were given;
Rate constant = 8.74 x 10^-4s^-1
Initial Concentration [A]o = 0.330M
Final concentration [A]= ?
Time = 800s
The reaction is a first order reaction, due to the unit of the rate constant. In first order reactions, the reaction rate is directly proportional to the reactant concentration and the units of first order rate constants are 1/sec.
Formular relating these parameters is given as;
ln[A] = ln[A]o − kt
Making [A] subject of interest, we have;
ln[A] = ln[A]o − kt
ln[A] = ln(0.330) - ( 8.74 x 10^-4 * 800)
In[A] = - 1.1086 - (6992 x 10^-4)
ln[A] = -1.8079
[A] = 0.1440M
A. MnS(s) + 2H + (aq) > Mn2 + (aq) + H2S(g)
It would convert into thermal that’s all I know.
The answer is Cartography.
They both use the elements Carbon and Oxygen, but carbon dioxide uses two oxygen.
