Molecular orbital theory correctly predicts paramagnetism of oxygen gas, o2. this is because ________.

1 answer:

3 0

Because the bond order in an oxygen gas is shown to be equal to 2, the idea furthermore supports the prediction of the molecular orbital theory in the paramagnetism of oxygen gas. This theory is primarily used when electrons are not included in the individual bonds for determining molecular structure.

How many moles Of H2O will be produced from 42.0 g of H2O2?

d1i1m1o1n [39]

$Molar{Mass} H_{2}O_{2} =2*16.0+2*1.0= 34.0 g/mol

42.0 g H_{2}O_{2}* \frac{1 mol H_{2}O_{2}}{34.0 g H_{2}O_{2}} = 1.24 mol H_{2}O_{2}

2H_{2}O_{2} --\ \textgreater \ 2 H_{2}O +O_{2}
\\2 mol ----2 mol (from// reaction)

\\1.24 mol ---1.24 mol (from the problem)

Answer: 1.24 mol H_{2}O.$

Consider the redox reaction below.

elixir [45]

Explanation:

Fe²⁺ + 2e⁻ → Fe

In a reduction half, the oxidizing agent is getting reduced. Such ion is donating electrons.

In a reduction process:

there is removal of oxygen from a specie
addition of hydrogen to a specie
gain of electron by an atom
decrease in oxidation number of an atom
decrease in number of electronegative atoms surrounding the element in changing from reactants to products.

Which of the newman structures below represents this conformation of 2-methyl-3-pentanol, as viewed along the c2-c3 bond?

castortr0y [4]

Answer:

(4) option is correct

Explanation:

Given that,

The conformation of 2-methyl-3-pentanol, as viewed along the C₂-C₃ bond.

We need to find the Newman structures

Using given structures

The structure of 2- methyl-3- pentanol is shown in figure.

Through C₂-C₃ carbon shown the structure of Newman projection in figure.

Here, carbon 2 is in front side and carbon 3 is in back side in the figure.

Hence, (4) option is correct.
