Answer:
The mass of silver chloride produced = 2.202 g
Explanation:
Equation of the reaction is given below
3AgNO₃(aq) + FeCl₃(aq) ----> 3AgCl(s) + Fe(NO₃)₃(aq)
molar mass of AgNO₃ = 170 g/mol
molar mass of FeCl₃ = 233.5 g/mol
molar mass of AgCl = 143.5 g/mol
3 moles of silver nitrate reacts with 1 mole of iron (iii) chloride to give 3 moles of silver nitrate
4.15 grams of AgNO₃ = 4.15/170 = 0.0244 moles of AgNO₃
1.11 grams of FeCl₃ = 1.11/233.5 = 0.0047 moles of FeCl₃
mole ratio of AgNO₃ to FeCl₃ = 0.0244/0.0047 = 5 : 1
therefore, FeCl₃ is the limiting reactant
0.0047 moles of FeCl₃ reacting will produce 0.0047 * 3 moles of AgCl = 0.0141 moles of AgCl
0.0141 moles of AgCl = 0.0141 * 143.5 g of AgCl = 2.02 g of AgCl =
Therefore mass of silver chloride produced = 2.202 g
Explanation:
Because molarity is mol/L, we'll have to convert 17g to mol.
After obtaining the mol, we'll divide that by the volume to obtain Molarity.
To solve this we use the equation,
M1V1 = M2V2
where M1 is the concentration of the stock
solution, V1 is the volume of the stock solution, M2 is the concentration of
the new solution and V2 is its volume.
65 x V1 = 2 x 200 L
V1 = 6.15 L
Answer:
3–ethyl–4–methylhexane.
Explanation:
To name the above compound, do the following:
1. Determine the functional group of the compound.
2. Locate the longest continuous carbon chain. This gives the parent name of the compound.
3. Identify the substituent group attached to the compound.
4. Give the substituent the lowest possible count.
5. Combine the above to name the compound.
Now, we shall name the compound given in the question above as follow:
1. The compound contains only single bond. Therefore, the compound belong to the alkane family.
2. The longest continuous carbon chain is 6 i.e hexane.
3. The substituent group attached are:
i. Methyl, CH3.
ii. Ethyl, CH2CH3.
4. we shall name the substituents alphabetically i.e ethly will come before methyl. Therefore,
Ethyl is located at carbon 3.
Methy is located at carbon 4.
5. Therefore, the name of the compound is:
3–ethyl–4–methylhexane.
I think it is enzymes.Inside our body most of the chemical reactions are speeds up by enzymes.These enzymes decreases the minimum energy that is required for the reaction to happen. ;-]. Actually it works like a catalyst.
