Explanation:

The given chemical equation is:

2A + 4B -> 2C + 2D

The rate of the reaction is 0.0352 M/s.

During the course of the reaction, the rate of reactants decreases, and the rate of products increases.

The rate of disappearance of B is shown below:

rate=-\frac{1}{4} \frac{d[B]}{dt}

So, rate of change of B is :

rate of change of B =- rate * 4\\=-0.0352 M/s * 4\\=-0.1408M/s\\\\=-0.141M/s

Option C.

Calculate the number of mol of S by 1.81
rodikova [14]
It’s 6.022x10^23. This is how many atoms of any element are in one mole of that element. No matter what it is, there are always 6.022x10^23 atoms per mole. So divide 1.81x10^24 by 6.022x10^23 to get approximately 3 moles of sulfur.
