The total area that could be covered by this roll of tape is 0.1524 m².

<h3>What is the double-sided tape?</h3>

A double-sided tape is a tape that can be stick from both sides. It is used to stick something on a surface. A rectangle is an object that has four sides in which two sides are equal.

If we unroll the tape, we will see that it is a rectangle with dimensions:

length = 6.35 m

width = 1.2 x 10⁻² m

Since the tape has two sides, the total area of the tape is:

A = 2 x (length x width)

A = 2 x 6.35 x 1.2 x 10⁻²

A = 0.1524 m²

Thus, the total area of the tape is 0.1524 m²

The following balanced equation shows the formation of ethane (C2H6).

almond37 [142]

Answer:

Explanation:

Well, we can see from the equation that hydrogen gas and ethane are in a 2:1 ratio based on their mole coefficients.

You need 2 mol H2 to make 1 mol C2H6. So that means you need 2*13.78 mol H2 to make 13.78 mol C2H6!

2*13.78 = 27.56 mol

C is correct.

Saponification is a chemical reaction _____. A. due to the presence of a strong organic acid. B. that results in an alcohol and

dezoksy [38]

Answer:

that results in an alcohol and a carboxylic acid.

Explanation:

Saponification is a chemical reaction process of alkaline hydrolysis of esters(R'COOR group) by which soap is obtained.

For Example, when a base such as sodium hydroxide [NaOH] is used to hydrolyze an ester, the products are a carboxylate salt and an alcohol. Because soaps are prepared by the alkaline hydrolysis of fats and oils.

In a saponification reaction, alkaline hydrolysis of fats and oils with sodium hydroxide yields propane-1,2,3-triol and the corresponding sodium salts of the component fatty acids.

i.e Fat or oil + caustic alkali ⇒ Soap + propane-1,2,3-triol

As a specific example, ethyl acetate and NaOH react to form sodium acetate and ethanol:

WHICH IS WHICH?

Aleksandr-060686 [28]

Answer:

- First: element.

- Second: Compound.

- Third: element.

- Fourth: Compound.

Explanation:

Hello.

In this case, since elements are composed the same atom and compounds are composed by two different atoms, we can see that:

- First: it is an element as each sphere seems to be the same.

- Second: It is a compound as two different type of spheres are shown, white and black, considering each sphere is a different element.

- Third: it is an element because the spheres are equal, in fact, it is a diatomic element as two atoms are joined per molecule.

- Fourth: It is a compound as well since each molecule has two colored spheres and one white sphere, meaning that it has two different atoms per molecule.

Best regards.!
