Ytu perform an electrolysis reaction using FeCl, iron (1) chloride. Which of the following will happen?
FrozenT [24]

Answer:

The answer is "Option B"

Explanation:

when we react with FeCl, iron, and chloride to both the electrolysis. So, iron is charged positive ion, as well as passes to the negative, is cathode electrode. But there is a decrease in the cathode.

The equation can be defined as follows:

FeCl_2 \longrightarrowFe + Cl_2

In the above equation, when the iron chloride electrolysis solution, it will give the iron(II) and the chlorine. This process happens when the hydrogen chloride solution at a temperature of about 90 ° C.

The density of a certain type of plastic is 0.81 g/cm3. If a sheet of this plastic is 10.0 m long, 1.0 m wide, and 1 cm thick, w
crimeas [40]

<u>Answer:</u> The mass of plastic sheet is 8.1\times 10^4g

<u>Explanation:</u>

The plastic sheet is in the form of cuboid. To calculate the volume of cuboid, we use the equation:

V=lbh

where,

V = volume of cuboid

l = length of cuboid = 10.0 m = 1000 cm     (Conversion factor: 1 m = 100 cm)

b = breadth of cuboid = 1.0 m = 100 cm

h = height of cuboid = 1 cm

Putting values in above equation, we get:

V=1000\times 100\times 1=10^5cm^3

To calculate mass of a substance, we use the equation:

\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}

We are given:

Density of plastic sheet = 0.81g/cm^3

Volume of plastic sheet = 10^5cm^3

Putting values in equation 1, we get:

0.81g/cm^3=\frac{\text{Mass of plastic sheet}}{10^5cm^3}\\\\\text{Mass of plastic sheet}=8.1\times 10^4g

Hence, the mass of plastic sheet is 8.1\times 10^4g
