In the electrolytic cell, depending on the polarity of the battery, either a more vigorous reaction (though the same as the voltaic cell) would occur, or the reverse would.

Why are there 2 chloride ions for every 1 calcium in calcium chloride
tensa zangetsu [6.8K]

Answer:

See explanation

Explanation:

Calcium is divalent. This means that it donates two electrons during ionic bond formation. Since chlorine atom can only accept one electron during ionic bond formation, two chlorine atoms must accept the two electrons donated by calcium.

For this purpose, each time CaCl2 is formed, there must be two chlorine atoms for each calcium atom.

What is the percentage composition of each element in Fe(OH)3
Bezzdna [24]

Answer:

Fe =52.2%, O = 44.9%, H = 2.81%

Explanation:

Percentage composition is also known as percentage by mass.

First, find the Mr of the compound.

Mr of Fe(OH)₃ = 55.8 + (16 × 3) + (1 × 3)

= 106.8

Now Divide the mass of the element, as per the compound, by the Mr of the compound found and times that by 100.

% composition of Fe = \frac{55.8}{106.8} × 100 = 52.2%

% composition of O = \frac{16*3}{106.8} × 100 = 44.9%

[There are 3 oxygen atoms in the compound Fe(OH)₃, so we will multiply the atomic mass of oxygen with the number of atoms in the compound: 16×3 ]

% composition of H = \frac{1*3}{106.8} × 100 = 2.81%

[There are 3 hydrogen atoms in the compound Fe(OH)₃, so we will multiply the atomic mass of hydrogen with the number of atoms in the compound: 1×3 ]
