Why do Adams become magnets win their electrons are properly arranged
kogti [31]
Atoms become "magnets" when their electrons are properly arranged because whenever they have not enough or too many electrons, they will want to either give away an electron or take an electron, causing them to bond to other things.

For the following reaction, 6.80 grams of hydrochloric acid are mixed with excess iron. The reaction yields 8.51 grams of iron(I
Orlov [11]

Answer:

A. 11.83g

B. 71.9%

Explanation:

We'll begin by writing the balanced for the reaction. This is shown below:

Fe + 2HCl —> FeCl2 + H2

A. Step 1

Determination of the mass of HCl that reacted and the mass of FeCl2 produced from the balanced equation. This is illustrated below:

Molar Mass of HCl = 1 + 35.5 = 36.5g/mol

Mass of HCl from the balanced equation = 2 x 36.5 = 73g

Molar Mass of FeCl2 = 56 + (35.5x2) = 56 + 71 = 127g

Summary:

From the balanced equation above,

73g of HCl produced 127g of FeCl2.

A. Step 2:

Determination of the theoretical yield of FeCl2.

The theoretical yield of FeCl2 can be obtained as follow:

Fe + 2HCl —> FeCl2 + H2

From the balanced equation above,

73g of HCl produced 127g of FeCl2.

Therefore, 6.80g of HCl will produce = (6.80 x 127)/73 = 11.83g of FeCl2.

Therefore, the theoretical yield of FeCl2 is 11.83g

B. Determination of the percentage yield.

Actual yield = 8.51g

Theoretical yield = 11.83g

Percentage yield =?

Percentage yield = Actual yield/Theoretical yield x100

Percentage yield = 8.51/11.83 x100

Percentage yield = 71.9%

Therefore, the percentage yield of FeCl2 is 71.9%
