Find the Hybridization of N in compound " NH3 " and determine its shape ~ ​

Answers

Answer 1

Let's check Electronic configuration of N in ground state

[tex]\\ \sf\longmapsto 1s^22s^22p^3[/tex]

In exited state

[tex]\\ \sf\longmapsto 1s^22s^22px^12py^12pz^2[/tex]

3 p orbitals

In hydrogen case

[tex]\\ \sf\longmapsto 1s^1[/tex]

1 s orbital

Hence Hybridization

[tex]\\ \sf\longmapsto s-p-p-p[/tex]

[tex]\\ \sf\longmapsto sp^3[/tex]

Structure is tetrahedral .

Spare way:-

A watch loses 0.15 sec/min, how many seconds are lost in 24 hours?

Answers

Answer:  

0.15 sec/min = 9 sec/hour

9*24 = 216 seconds = 3.6 minutes

Explanation:

Answer:

216 Seconds

Explanation:

If every minute is 60 seconds than 60 multiplied by .15 is 9 Seconds Lost.

If every hour is 60 minutes compared to what we know than 24 hours multiplied by 60 is 1440 minutes.

Do the same math as before: 1440 x .15 = 216 Seconds

Question:-

If a solid object is taken from Earth far into space, which of the following measurements of the object will change the most?

A. density

B. mass

C. volume

D. weight

Answer:-

option D. weight

The first stage of the experiment is focusing only on the physical properties of acidic property.

What is physical property?

A physical property would be any quantifiable attribute whose value describes the condition of a physical system. Changes in a system's physical attributes are able to characterize its transitions between brief states. Physical attributes are sometimes known as observables.

Physical characteristics are frequently classified as intense or extensive. An intense property is independent of the system's size or extent, as well as the amount of material in the item, whereas an extended property has an additive link. The first stage of the experiment is focusing only on the physical properties of acidic property.

Therefore, the first stage of the experiment is focusing only on the physical properties of acidic property.

Charlotte has some copper sulfate solution. She wants solid copper sulfate. Which technique should she use?

Answers

Answer:

She should use the crystalization technique

Explanation:

First, the copper sulfate solution should be filtered to clear any impurities.

By heating the solution of copper sulfate on a china dish, the excess water in the solution evaporates and leaves behind a saturated solution of copper sulfate.

Upon cooling this saturated copper sulfate solution, crystals of solid copper sulfate will be formed on the china dish.

In solid form, copper sulfate appears in triclinic-shaped crystals.

Convert 4.0 moles of krypton into liters of krypton.

Answers

Answer:

4.0 moles of krypton converts to 89.6L.

Explanation:

To convert moles to liters, remember that at standard temperature and pressure (STP), 1 mole is equal to 22.4 liters. Multiply your mole value - in this case, 4.0 - by the molar volume constant, 22.4L, to convert moles into liters. 4.0 x 22.4 is equal to 89.6, thus your answer is 89.6L.

We can check this by dividing 89.6 by 4.0, which will give us the molar volume constant 22.4L, proving that this answer is correct.

Chlorine and oxygen form many different compounds, including CIO, and Cl2O3. How do the names of these compounds differentiate one chlorine oxide from another?​

Answers

Answer:

We can mix two compounds and create a third that bears little resemblance to its parents. For instance, by mixing two parts of hydrogen gas with one of oxygen - liquid water is formed. We should not be misled by the fact that chlorine and chlorine dioxide share a word in common. The chemistries of the two compounds are completely different.

Chlorine and chlorine dioxide are both oxidizing agents (electron receivers). However, chlorine has the capacity to take in two electrons, whereas chlorine dioxide can absorb five. This means that mole for mole, ClO2 is 2.6 times more effective than chlorine.

If equal, if not greater importance is the fact that chlorine dioxide will not react with many organic compounds, and as a result, ClO2 does not produce environmentally dangerous chlorinated organics. For example; aromatic compounds have carbon atoms arranged in rings and they may have other atoms, such as chlorine, attached to these rings, to form a chlorinated aromatic - a highly toxic compound that persists in the environment long after it is produced.  

Chlorine dioxide's behaviour as an oxidizing agent is quite dissimilar. Like ozone, the predominant oxidation reaction mechanism for chlorine dioxide proceeds through a process known as free radical electrophilic (i.e. electron-attracting) abstraction rather than by oxidative substitution or addition (as in chlorinating agents such as chlorine or hypochlorite). This means that chlorinated organic compounds such as THMs and HAAs are not produced as a result of disinfection using chlorine dioxide

Hope this helps, have a nice day! :D

The way that the names of these compounds show that the Chlorine oxides are different is by making reference to the number of individual molecules in the compound.

How are the chlorine oxides differentiated?

The number of chlorine and oxygen molecules in each compound are used to name the compounds which ensures that they are differentiated.

ClO₂ is called "Chlorine Dioxide" which shows that there are two Oxygen atoms.

Cl₂O₃ is called "Dichlorine Trioxide" which shows that there are two Chlorine molecules and 3 Oxygen molecules.
