Draw a Lewis structure for HCCl3 . Include all hydrogen atoms and show all unshared pairs and the formal charges, if any. Assume
andrey2020 [161]

Answer:

See answer below

Explanation:

First, let's explain what a Lewis structure is.

A lewis structure in short words is a draw of an atom or molecule showing how the electrons bond with another electrons of atoms, and also shows the unshared pair of electrons, which are the electrons that do not bond in the molecule. In the case of an atom, it shows all the available electrons it has to be shared and bonded with another atom to form a molecule.

With this said, in order to draw the lewis structure we need to know how many electrons the atoms involved have. To know this, we need to write the electronic configuration of the atoms, based on it's atomic number.

In the case of Hydrogen (Z = 1), Carbon (Z = 6) and Cl (Z = 17):

[H] = 1s¹     1 electron available.

[C] = 1s² 2s² 2p²   In this case, we have 4 electrons.

[Cl] = 1s² 2s² 2p⁶ 3s² 3p⁵  In this case, 7 electrons.

Now that we have the configuration, and the available electrons, we need to draw the atoms. The Carbon is the more electronegative atom of them, so, the bonding will be formed based on this atom as the central. So the other atoms will just bond and shared a pair of electron with the carbon. The HCCl₃ can be treated as CH₄, with a tetrahedrical form.

The picture below shows the lewis structure.

Hope this helps

What is the approximate volume injected into a GC? 10-50 μL 500-1000 μL 1-10 μL 100-500 μL 50-100 μL What technique is used to a
DiKsa [7]

Answer:

1-10 μL

Explanation:

Gas Chromatography (GC) is a method of separating the constituents of a complex mixture by taking advantage of their different rates of movement in a solvent over an adsorbent medium. Gas Chromatography (GC) is a means of separation and analysis that utilises fractional separation. It is based on the principle that if a fluid containing a number of substances is allowed to pass through an adsorbent medium , the different substances in the fluid may travel at different rates and be separated.

The approximate volume injected through an inlet by using a split injection into a Gas Chromatography (GC) contains a sample with an approximate value of analyte which varies from  1-10 μL.

In order to adjust for injection volume inaccuracy, the technique used is known as  Internal Standard.

Ammonium perchlorate NH4ClO4 is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen
svet-max [94.6K]

Answer: 0.99 grams of chlorine gas is produced by the reaction of 3.3g of ammonium perchlorate

Explanation:

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}  

\text{Number of moles of } NH_4ClO_4=\frac{3.3g}{117.5g/mol}=0.028moles

The decomposition of ammonium perchlorate is :

2NH_4ClO_4\rightarrow Cl_2+N_2+2O_2+4H_2O

According to stoichiometry :

2 moles of NH_4ClO_4 produce =  1 mole of Cl_2

Thus 0.028 moles of NH_4ClO_4 produce=\frac{1}{2}\times 0.028=0.014moles  of Cl_2  

Mass of Cl_2=moles\times {\text {Molar mass}}=0.014moles\times 71g/mol=0.99g

Thus 0.99 grams of chlorine gas is produced by the reaction of 3.3g of ammonium perchlorate
