Select the correct value for the indicated bond angle in each of the compounds.

Ira Lisetskai [31]

Answer:

Bond angle is defined as the angle between two or more bonds or bonded electron pairs in a compound.

Explanation:

a) O−O−O angle of O3 - <120°

b) F−B−F angle of BF3 - 120°

c) F−O−F angle of OF2 - <109.5

d) Cl−Be−Cl angle of BeCl2 - 180°

What is the volume occupied by 3.00 × 1023 molecules of bromine gas at STP?

Jet001 [13]

D. 11.2 L , since we are at STP we will use the ideal gas law. 3.0 x 10²³ 6.02x10²³ / 1 mole and if you continue with this process it will give you 11 L.

Allotropes are different molecular forms of an element, such as dioxygen (O₂) and ozone (O₃). (b) Calculate the ratio of densiti

kipiarov [429]

The ratio of densities, d₀₃/d₀ is 3:2

We know that at STP all gas have the same volume that is $22.4 \mathrm{~L}$ .

Dioxygen $1 \mathrm{mLe} \mathrm{O}_{2}=32 \mathrm{gm} / \mathrm{moL} .$

Ozone 1 mole $\mathrm{O}_{3}=48 \mathrm{gm} / \mathrm{mol}$ .

$\begin{aligned} \therefore \text { density of } \mathrm{O}_{2} \text { at STP } &=\frac{\text { mass of } \mathrm{O}_{2}}{\text { volume }} \\ \text { or, } d_{\mathrm{O}_{2}} &=\frac{32 \mathrm{gm} / \mathrm{mol}_{\mathrm{o}}}{22.4 \mathrm{~L}} \end{aligned}$

$\therefore$ The ratio of densities,

$\frac{d_{3}}{d o_{2}}=\frac{\frac{48 \mathrm{gm} / \mathrm{mol}}{22.4 \mathrm{~L}}}{\frac{32 \mathrm{gm} / \mathrm{mol}}{22.4 \mathrm{~L}}}$

$\frac{d 0_{3}}{d 0_{2}}=\frac{3}{2}$

do3: do2 = 3:2

Oxygen is found naturally as a molecule. two oxygen atoms strongly bind together with a covalent double bond to shape dioxygen or O2. Oxygen is normally observed as a molecule. it is referred to as dioxygen.

After hydrogen and helium, oxygen is the third most plentiful element in the universe and the most established element in the world. two atoms of the factors combine to generate dioxygen, an odourless and colourless diatomic gasoline with the formulation O2, at ordinary temperature and stress.
