Give the following for SO2 and BrF5:
frosja888 [35]

Answer:

The given molecules are SO2 and BrF5.

Explanation:

Consider the molecule SO2:

The central atom is S.

The number of domains on S in this molecule is three.

Domain geometry is trigonal planar.

But there is a lone pair on the central atom.

So, according to VSEPR theory,

the molecular geometry becomes bent or V-shape.

Hybridization on the central atom is

sp^{2}.

Consider the molecule BrF5:

The central atom is Br.

The number of domains on the central atom is six.

Domain geometry is octahedral.

But the central atom has a lone pair of electrons.

So, the molecular geometry becomes square pyramidal.

The hybridization of the central atom is sp^{3} d^{2}.

The shapes of SO2 and BrF5 are shown below:

The rock in a particular iron ore deposit contains 82 % Fe2O3 by mass. How many kilograms of the rock must be processed to obtai
Zinaida [17]

Answer:

Mass of rock = 4533.4 kg

Explanation:

Percent composition is percentage by the mass of element present in the compound.

Given that the Fe_2O_3 is 82 % by mass.

It means that 82 kg of Fe_2O_3 is present in 100 kg of rock

To find the mass of rock which contains 2600 kg of iron

2600 kg = 2600*1000 g

2 moles of iron are present in 1 mole of Fe_2O_3

Molar mass of iron = 55.845 g/mol

Mass of 2 moles = 55.845 * 2 = 111.69 g/mol

Molar mass of Fe_2O_3 = 159.69 g/mol

It means,

111.69 g of iron are present in 159.69 g of Fe_2O_3

1 g of iron is present in 159.69/111.69 g of Fe_2O_3

2600*1000 g is present in (159.69/111.69)*2600*1000 g of Fe_2O_3

Mass of  Fe_2O_3 = 3717378.47 g =3717.38 kg

Thus,

82 kg of Fe_2O_3 is present in 100 kg of rock

1 kg of Fe_2O_3 is present in 100/82 kg of rock

3717.38 kg of Fe_2O_3 is present in (100/82)*3717.38 kg of rock

Mass of rock = 4533.4 kg
