Predict the geometry about each interior atom in acetic acid:

aleksandr82 [10.1K]

The atomic structure of the acetic acid is:

H O

l l

H – C – C – O – H

l

H

We can see from the structure that there are 2 interior atoms, and these are all Carbon atoms.

The geometry is:

Tetrahedral on First Carbon

Trigonal Planar on Second Carbon

Single and double replacement reactions practice WS CuCl2 +<br> F2 »<br> CuF2<br> +<br> Cl2

Lapatulllka [165]

CuCl2+F2—>CuF2+Cl2.
This is a single replacement because there is one compound and one element. Picture Cu as ‘A’ Cl2 as ‘B’ and F2 as ‘C.’ So AB+C—>AC+B. A and B “broke up” and that resulted to A going with C to create the compound CuF2 leaving Cl2 alone.

What two parts are needed to make a neutral atom of neon

almond37 [142]

Answer:

it needs two electrons in the first and eight to fill the second.

Explanation:

Because neon has two atomic shells, it needs two electrons in the first and eight to fill the second. Neon has a total of ten electrons which means two filled shells.

The flask contains 10.0 mL 10.0 mL of HCl HCl and a few drops of phenolphthalein indicator. The buret contains 0.130 M NaOH . 0.

Lyrx [107]

The question is incomplete, here is the complete question:

The flask contains 10.0 mL of HCl and a few drops of phenolphthalein indicator. The buret contains 0.130 M NaOH. It requires 32.4 mL of the NaOH solution to reach the end point of the titration. What is the concentration of HCl ?

<u>Answer:</u> The concentration of HCl is 0.421 M

<u>Explanation:</u>

To calculate the concentration of acid, we use the equation given by neutralization reaction:

$n_1M_1V_1=n_2M_2V_2$

where,

$n_1,M_1\text{ and }V_1$ are the n-factor, molarity and volume of acid which is HCl

$n_2,M_2\text{ and }V_2$ are the n-factor, molarity and volume of base which is NaOH.

We are given:

$n_1=1\\M_1=?M\\V_1=10.0mL\\n_2=1\\M_2=0.130M\\V_2=32.4mL$

Putting values in above equation, we get:

$1\times M_1\times 10.0=1\times 0.130\times 32.4\\\\M_1=\frac{1\times 0.130\times 32.4}{1\times 10.0}=0.421M$

Hence, the concentration of HCl is 0.421 M
