Answer:
Percentage of an aldrin in the sample is 44.41%.
Explanation:
Molarity of the silver nitrate solution = 0.03337 M
Volume of the silver nitrate = 23.28 mL = 0.02328 L
Moles of silver nitrate = n
n = 
According to reaction 1 mole of silver nitrate recats with 1 moles of chloride ions.
Then 0.0007768 moles of silver nitrate will react with:
chloride ions.
In one mole of aldrin there are 6 moles of chloride ions.
Then moles of aldrin containing 0.0007768 moles chloride ions are:
Moles of aldrin present in the sample = 0.0001295 mol
Mass of 0.0001295 moles of aldrin present in the sample :
0.0001295 mol × 364.92 g/mol =0.04726 g
Percentage of an aldrin in the sample:
<u>Answer:</u> The chemical equation is written below.
<u>Explanation:</u>
Combustion reaction is defined as the chemical reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule.
The chemical equation for the combustion of ethyl chloride follows:
We are given:
When 4 moles of ethyl chloride is burnt, 5145 kJ of heat is released.
For an endothermic reaction, heat is getting absorbed during a chemical reaction and is written on the reactant side.
For an exothermic reaction, heat is getting released during a chemical reaction and is written on the product side
So, the chemical equation follows:
Hence, the chemical equation is written above.
Answer:
Rydberg constant 3.3 x 10¹⁵ Hertz is equal to 1.090 x 10⁷ m⁻¹
Explanation:
Given;
Rydberg constant as 3.3 x 10¹⁵ Hz
1 Rydberg constant = 3.3 x 10¹⁵ Hz
1 Rydberg constant = 1.090 x 10⁷ m⁻¹
Therefore, Rydberg constant 3.3 x 10¹⁵ Hertz is equal to 1.090 x 10⁷ m⁻¹
Answer:
Polymerization.
Explanation:
Polymerization can be defined as a type of chemical reaction in which molecules that are relatively small in size chemically combine to form a huge chain of molecules.
Simply stated, polymerization refers to a chemical reaction where two or more smaller molecules react to produce larger molecules of the same network or repetitive structural units.
In polymerization, the relatively small molecules are generally referred to as monomers while the larger molecules they produce are known as polymers.
Polymerization is given by the chemical formula;
nA -----> A(n).
In this scenario, Luis uses a stencil to repeat the same design on each wall to form one long grapevine with a bunch of grapes every foot along its length.
Hence, the type of chemical reaction this best model is polymerization because it involved repeating the same design (monomers) to form a long grapevine with a bunch of grapes (polymers).
Answer: Molarity of 
in the original sample was 1.96M
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.
Now put all the given values in the formula of molarity, we get
Thus molarity of in the original sample was 1.96M
