On the first graph the beginning flat line is the reaction. Then comes the hill will it be call the activation energy. The final flat line would be the produce. Same names apply to the 2 graph too
They vibrate back and forth
Answer: The molecular formula is 
Explanation:
We are given:
Mass of 
= 0.1605 g
Mass of 
= 0.0220 g
mass of 
= 0.1425 g
Step 1 : convert given masses into moles.
Moles of C =
Moles of H =
Moles of S =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C = 
For H = 
For S =
The ratio of C : H: S= 3: 5: 1
Hence the empirical formula is 
The empirical weight of = 3(12)+5(1)+1(32)= 73g.
The molecular weight = 146 g/mole
Now we have to calculate the molecular formula.
The molecular formula will be=
La materia no se crea ni se destruye solo se transforma
Explanation:
«En toda reacción química la masa se conserva, es decir, la masa total de los reactivos es igual a la masa total de los productos».
Los átomos ni de crean ni se destruyen,durante una reacción química.Por lo tanto una ecuación química ha de tener el mismo numero de atomos de cada elemento a ambos lados de la flecha. Se dice entonces que la ecuación esta balanceada
Espero y te sirva!!
It is either D or B
