Answer: option A

Explanation:

Since Fluorine belongs to 7A group it should have 7 valency electrons in outer shell which is observed in option A.

But all options have 7 electrons in total. But we know that F has 3 unpaired and one odd electron separately which is coincide with option A hence it is the correct answer.

When 1.57 mol o2 reacts with h2 to form h2o, how many moles of h2 are consumed in the process?

natita [175]

Here we have to get the moles of hydrogen (H₂) consumed to form water (H₂O) from 1.57 moles of oxygen (O₂)

In this process 3.14 moles of H₂ will be consumed.

The balanced reaction between oxygen (O₂) and hydrogen (H₂); both of which are in gaseous state to form water, which is liquid in nature can be written as-

2H₂ (g) + O₂ (g) = 2H₂O (l).

Thus form the equation we can see that 1 mole of oxygen reacts with 2 moles of hydrogen to form 2 moles of water.

So, 1.57 moles of oxygen will consume (1.57×2) = 3.14 moles of hydrogen to form water.

NO2 can react with the NO in smog, forming a bond between the N atoms. Draw the structure of the resulting compound, including f

ELEN [110]

First, let's write down the balanced chemical reaction between the given reactants:

NO₂ + NO → N₂O + O₂

The Lewis structure of the main product is shown in the attached picture. To determine the formal charge of each element, the formula is as follows:

Formal Charge = Valence electrons - Non-bonding valence electrons - (Bonding electrons/2)

For the leftmost N:
Formal charge = 5 - 2 - 6/2 = 0
For the middle N:
Formal charge = 5 - 0 - 8/2 = 1
For O:
Formal charge = 6 - 6 - 2/2 = -1

An important reaction sequence in the industrial production of nitric acid is the following: N2(g) + 3H2(g) → 2NH3(g) 4NH3(g) +

frutty [35]

Answer:

The answer to your question is 50 moles of O₂

Explanation:

Balanced Chemical reactions

1.- N₂(g) + 3H₂ (g) ⇒ 2NH₃ (g)

2.- 4NH₃ (g) + 5O₂(g) ⇒ 4NO (g) + 6H₂O (l)

moles of N₂(g) = 20 moles

moles of O₂(g) = ?

Process

1.- Calculate the moles of NH₃

1 mol of N₂ ------------- 2 moles of NH₃

20 moles of N₂ --------- x

x = (20 x 2) / 1

x = 40 moles of NH₃

2.- Calculate the moles of O₂

4 moles of NH₃ -------------- 5 O₂

40 moles of NH₃ ------------ x

x = (40 x 5) / 4

x = 200 / 4

x = 50 moles of O₂
