Elina [12.6K]

Answer:

155 A

Explanation:

Given data

  • Transported charge (Q): 93.0 Coulomb
  • Elapsed time (t): 601 ms = 0.601 seconds

We can determine the magnitude of the electric current (I) using the following expression.

I = Q / t

I = 93.0 C / 0.601 s

I = 155 C/s

I = 155 A

The magnitude of the electric current is 155 Ampere.

Please help me with this chemistry question. Image attached.
Leya [2.2K]

Answer:

Moles of zinc chloride produced are 0.09942 moles.

Explanation:

Zn+2HCl\rightarrow ZnCl_2+H_2

Mass of zinc used = 6.5 g

Moles of zinc =\frac{6.5 g}{65.38 g/mol}=0.09942 mol

According to reaction, 1 mol of zinc gives 1 mole of zinc chloride,then 0.09942 moles of zinc will give :

\frac{1}{1}\times 0.09942 =0.09942 mol of zinc chloride

Moles of zinc chloride produced are 0.09942 moles.

Categorize each hydrocarbon as being saturated or unsaturated.
Black_prince [1.1K]

As you have not provided the options, still we can figure out the answer by understanding the key difference between saturated and unsaturated hydrocarbons.

SATURATED HYDROCARBONS are those hydrocarbons which only consist of a carbon carbon single bonds. All the bonds are sigma there are no pi bonds at all. Examples are shown below.

While, UNSATURATED HYDROCARBONS are those hydrocarbons which may contain either a double bond or triple bonds or both of them between the carbon atoms as shown below.
