Explanations:- Looking at the given name, the parent chain name is Oct and Oct stands for eight carbons.

The suffix -ene at number 5 stands for a double bond between carbon number 5 and 6.

Bro stands for Br. Since the name has dibromo means there are two Br at number 3 and 7 carbons.

Similarly, there are two Cl at number 4 and 6 carbons.

Suffix -ol is used for OH group. The given name has 1,2-diol means there are two OH groups at number 1 and 2 carbons.

So, to draw the structure of the compound we put 8 carbons in a chain and then but a double bond between number 5 and 6 carbons. Put OH at number 1 and 2 carbons, put Br at number 3 and 7 carbons and Cl at number 4 and 6 carbons. If any of the carbons octet (four bonds) is still incomplete then we attach H atoms to it.

So, the structure of the compound is as given below:

The concentration of potassium cyanide (KCN) in a sample of water is 9.65 x 10-7 M. Assume the density of

bagirrra123 [75]

The concentration in ppm is 0.06 ppm

<h3>How to convert to PPM?</h3>

There are several unit of concentration in chemistry. Let us recall that concentration is the amount of substance that is present in a solution. Thus we have;

Concentration = 9.65 x 10-7 M

Molar mass of potassium cyanide = 65 g/mol

Thus;

M = ppm/MM * 1000

M = molar concentration

MM = molar mass

M * MM * 1000 = ppm

ppm = 9.65 x 10-7 M * 65 g/mol * 1000

ppm = 0.06 ppm

How can you distinguish between a physical change and a chemical change?

AleksAgata [21]

Answer:

Physical Change

When a substance undergoes a physical change, its composition remains the same despite its molecules being rearranged.
Physical change is a temporary change.
A Physical change affects only physical properties i.e. shape, size, etc.
A physical change involves very little to no absorption of energy.
Some examples of physical change are freezing of water, melting of wax, boiling of water, etc. .
In a physical change, no new substance is formed.
Physical change is easily reversible i.e original substance can be recovered.

Chemical Change

When a substance undergoes a chemical change, its molecular composition is changed entirely. Thus, chemical changes involve the formation of new substances.
.A chemical change is a permanent change.
Chemical change both physical and chemical properties of the substance including its composition
During a chemical reaction, absorption and evolution of energy take place.
A few examples of chemical change are digestion of food, burning of coal, rusting, etc.
A chemical change is always accompanied by one or more new substance(s).
Chemical changes are irreversible i.e. original substance cannot be recovered.

an aqeous solution of oxalic acid h2c2o4 was prepared by dissolving a 0.5842g of solute in enough water to make a 100 ml solutio

vampirchik [111]

The question is incomplete, here is the complete question:

An aqeous solution of oxalic acid was prepared by dissolving a 0.5842 g of solute in enough water to make a 100 ml solution a 10 ml aliquot of this solution was then transferred to a volumetric flask and diluted to a final volume of 250 ml. How many grams of oxalic acid are in 100. mL of the final solution?

<u>Answer:</u> The mass of oxalic acid in final solution is 0.0234 grams

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$ ......(1)

Given mass of oxalic acid = 0.5842 g

Molar mass of oxalic acid = 90 g/mol

Volume of solution = 100 mL

Putting values in equation 1, we get:

$\text{Molarity of oxalic acid solution}=\frac{0.5842\times 1000}{90\times 100}\\\\\text{Molarity of oxalic acid solution}=0.0649M$

To calculate the molarity of the diluted solution, we use the equation:

$M_1V_1=M_2V_2$

where,

$M_1\text{ and }V_1$ are the molarity and volume of the concentrated oxalic acid solution

$M_2\text{ and }V_2$ are the molarity and volume of diluted oxalic acid solution

We are given:

$M_1=0.0649M\\V_1=10mL\\M_2=?M\\V_2=250.0mL$

Putting values in above equation, we get:

$0.0649\times 10=M_2\times 250.0\\\\M_2=\frac{0.0649\times 10}{250}=0.0026M$

Now, calculating the mass of glucose by using equation 1, we get:

Molarity of oxalic acid solution = 0.0026 M

Molar mass of oxalic acid = 90 g/mol

Volume of solution = 100 mL

Putting values in equation 1, we get:

$0.0026=\frac{\text{Mass of oxalic acid solution}\times 1000}{90\times 100}\\\\\text{Mass of oxalic acid solution}=\frac{0.0026\times 90\times 100}{1000}=0.0234g$

Hence, the mass of oxalic acid in final solution is 0.0234 grams
