n the first step of the industrial process for making nitric acid, ammonia reacts with oxygen in the presence of a suitable cata

MariettaO [177]

Answer:

10.54 L

Explanation:

Given that:-

Moles of $O_2$ = 1.00 moles

According to the given reaction:-

$4NH_3+7O_2\rightarrow 4NO_2+6H_2O$

7 moles of oxygen gas reacts with 4 moles of ammonia

1 mole of oxygen gas reacts with $\frac{4}{7}$ moles of ammonia

Moles of ammonia = 0.5714 moles

Also, Given that:

Temperature = 850 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

So,

T₁ = (850 + 273.15) K = 1123.15 K

n = 0.5714 moles

P = 5.00 atm

Using ideal gas equation as:

$PV=nRT$

where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature

R is Gas constant having value = 0.0821 L atm/ K mol

Applying the equation as:

5.00 atm × V = 0.5714 moles ×0.0821 L atm/ K mol × 1123.15 K

⇒V = 10.54 L

<u>10.54 L of $NH_3$ required.</u>

Predict the bond angles for each of the following labeled bonds.

boyakko [2]

The bond angles a and b are 120° respectively. The bond angle c is 111.4° .while the bond angle d is 120°. The bond angles e and f are 120° respectively.

In the carbonate ion, all the bond angles and bond lengths are equal hence three equivalent resonance structures can be drawn for the ion. All the bond angles, ( a and b) in carbonate ion all have bond angle of 120°.

The bond angle marked c in OCCl2 has a bond angle 111.4°, the bond angle marked d in the compound has the bond angle, 120°.

There are three bond angles present in the nitrate (NO3-) ion. Three resonance structures contribute to this bond. Based on these structures, the bond angles e and f in the molecule is 120°.

A/1 * B/C = D

grigory [225]

Answer : 4.8 florins can you exchange for your 4 guilders.

Solution : Given,

The current exchange rate for every 2.4 florins is 2.0 guilders

As per question,

The exchange rate is 2.0 guilders for every 2.4 florins

The exchange rate is 1 guilders for every $\frac{2.4}{2.0}$ florins

The exchange rate is 4 guilders for every $\frac{2.4}{2.0}\times 4=4.8$ florins

Therefore, the 4.8 florins can you exchange for your 4 guilders.

What is the formula of the ionic compound expected to form between the elements cl and al?

patriot [66]

Ionic compounds are those compounds which are made up of ions. These ions can exist as positive or negative ions. Those ions which has tendency to lose electrons are said to be cations (positive ions) such as metals and those ions which has tendency to gain electrons are said to be anions (negative ions) such as non-metals.

The formula for ionic compounds are given as:

First, the symbols of the cation and anion should be identified. After that, charge on the cation and anion should be identified. Write the chemical formula with the help of drop and swap method.

Now,

The chemical symbols for Aluminium is $Al$ and for chlorine is $Cl$ .

The charge on $Al$ is +3 and on $Cl$ is -1, neglect the positive and negative signs and by using drop and swap method i.e. the charge on the aluminium will go as a subscript of the chlorine and the charge on the chlorine will go as a subscript of the aluminium which is shown in the image.

Thus, the chemical formula between $Al$ and $Cl$ is $AlCl_{3}$ .
