luda_lava [24]

Answer:

When you put sugar inside of a cup with water, the sugar is still visible because it's molecules have just gotten in touch with water molecules. The sugar molecules are still attracted to each other but as you stir it, it seems to disappear but not completely. When the water is stirred sugar mix with water and water molecules place themselves between the sugar ones.

Conclusion: It suggests that the sugar molecules are more attracted to water molecules which is why they easily separate from each other.

Explanation: The given compound is an organic compound because it has hydrogen and carbon atoms in it.

Skeletal structure of an organic compound is defined as a structure which is composed of the skeletal atoms that are used to define a structure.

In organic chemistry, the skeletal atoms are hydrogen and carbon. The atoms other than hydrogen and carbon are termed as heteroatoms and are shown in the structure.

The skeletal structure of 3-methyl-1-butanethiol is given in the image attached.

Here, the functional group is thiol group which has a heteroatom S.

For the reaction, 2cr2+ + cl2(g) ---> 2cr3+ + 2cl- e cell (standard conditions) = 1.78v calculate ecell (standard conditions)

PolarNik [594]

Answer:

-1.78 V

Explanation:

There are several rules required to calculate the cell potential:

given standard cell potential, we may reverse the equation: the products of a given reaction become our reactants, while reactants become our products in the reversed equation. For a reversed equation, we change the sign of the cell potential to the opposite sign;
if we multiply the whole equation by some number, this doesn't influence the cell potential value. It only produces a different expression in the equilibrium constant.

That said, notice that the initial reaction with respect to the final reaction is:

reversed: chromium(III) cation and chloride anion become our reactants as opposed to the products in the initial reaction, so we change the sign of the cell potential to a negative value of -1.78 V;
each coefficient is multiplied by a fraction of $\frac{1}{2}$ . It doesn't influence the value of the cell potential.

Thus, we have a cell of E = -1.78 V.
