Determine the mass of oxygen produced in the decomposition of 25.0 g of potassium
chlorate, which would also yield the formation of potassium chloride. Show steps please!

9.80g of O2.

Explanation:

Step 1:

The balanced equation for the reaction. This is given below:

2KClO3 —> 2KCl + 3O2

Step 2:

Determination of the mass of KClO3 that decomposed and the mass of O2 produced from the balanced equation. This is illustrated below:

Molar Mass of KClO3 = 39 + 35.5 + (16x3) = 122.5g/mol

Mass of KClO3 from the balanced equation = 2 x 122.5 = 245g

Molar Mass of O2 = 16x2 = 32g/mol

Mass of O2 from the balanced equation = 3 x 32 = 96g.

From the balanced equation above, 245g of KClO3 decomposed to produce 96g of O2.

Step 3:

Determination of the mass of O2 produced in the decomposition of 25.0g of KClO3. This is illustrated below:

From the balanced equation above, 245g of KClO3 decomposed to produce 96g of O2.

Therefore, 25g of KClO3 will decompose to produce = (25x96)/245 =

9.80g of O2.

Therefore, 9.80g of O2 is produced from the decomposition of 25g of KClO3.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
