Question 2. (14 mks) Copper(II) oxide catalyses the decomposition of hydrogen peroxide. 0.5 g of the oxide was added to a flask containing 100 cm3 of hydrogen peroxide solution. A gas was released. It was collected, and its volume noted every 10 seconds. This table shows the results: Tunels 0 10 20 30 40 50 60 70 80 90 Volume/cm3 0 18 30 40 48 53 57 58 58 58 name the gas that is formed?​

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.  

yes

indium, and thallium have three electrons i think
