How many numbers of atoms there are in 1.14 mol of (SO3)

Chemistry
1 answer:
Pachacha [2.7K]3 years ago
8 0

called the Avogadro number 

N(A)= 6.02 x 10^23 mol^-1 

1 mole of SO3 will contain 6.02 x 10^23 mol^-1 of SO3 molecules. 

thus, 1.14moles will contain; 

= 1.14mol x [3mol O/1mol SO3] x [6.02 x 10^23

atoms O/1mol O] 

= 2.05884 x 10^24 oxygen atoms 

= 1.14mol x [1mol S/1mol SO3] x [6.02 x 10^23

atoms O/1mol O] 

= 6.8628 x 10^23 sulfur atoms 

hope this helps:-)

Calculate the pH of a solution with an H+ ion concentration of 9.36 x 10-3 M ?
mel-nik [20]

Answer:

The answer is 2.03

Explanation:

The pH of a solution can be found by using the formula

pH = - log [ {H}^{+} ]

where H+ is the Hydrogen ion concentration

From the question we have

pH =  -  log(9.36 \times  {10}^{ - 3} )  \\  = 2.02872415...

We have the final answer as

<h3>2.03 </h3>

Hope this helps you

Describe the experimental basis for believing that the nucleus occupies a very small fraction of the volume of the atom.
svetlana [45]

Explanation:

Rutherford conducted an experiment in which he took a thin gold particle film on which he passes alpha- particles. He noticed that:

  • Most of the alpha particles get through the film and can be detected by the detector.
  • Around small portion of the alpha particle deflected at small angles.
  • A very very few alpha particle (approximately 1 out of 1 million alpha particles) just retraced their path which means come back from the center.

He concluded that:

<u>Most of the space of the atom is empty and in the center of the atom , there is solid mass which is the cause of the alpha particles to come back. He gave the term nucleus to this solid mass.</u>

The reaction of iron with oxygen to form iron oxide is an example of an oxidation–reduction reaction: 4fe + 3o2 → 2fe2o3. in thi
nadya68 [22]

Answer:-

Oxygen gains electrons and is reduced.

Explanation:-

For this reaction the balanced chemical equation is

4Fe + 3O2 --> 2Fe2O3

When Oxygen is present as oxygen gas, the oxidation number of O is Zero since it is the only element present in Oxygen gas.

Similarly Iron is present in Fe with oxidation number Zero.

In the case of Fe2O3, Oxygen has the oxidation number -2 while Iron has +3.

So the oxidation number of Oxygen goes from Zero to -2.

Since the oxidation number decreases Oxygen is reduced.

Since reduction involves gain of electrons, Oxygen gains electrons.
