Answer:
Nitrogen A would be more nucleophilicity (figure 1.)
Explanation:
In the <u>DMAP </u>molecule we will have 2 nitrogens label as "nitrogen A" and "nitrogen B". For nitrogen B we will have more<u> steric hindrance</u> due to the 2 methyls groups and the benzene ring. What will hinder the attack from this nitrogen (nitrogen B) to an <u>electrophile</u>. On the contrary, the attack of nitrogen A could easily occur.
Answer : The balanced redox reaction will be,
Explanation :
The given chemical equation is,
In the half reaction method, the number of atoms in each half reaction and number of electrons must be balanced.
The half reactions in the acidic medium are :
Reduction : ......(1)
Oxidation : .......(2)
Now multiply the equation (1) by 2 and equation (2) by 3 then added both equation, we get the balanced redox reaction.
Thus, the balanced redox reaction will be,
The balanced equation for the reaction is as follows
Cu₂O + 2HCl ---> 2CuCl + H₂O
Molar ratio of Cu₂O to CuCl is 1:2
mass of Cu₂O reacted - 73.5 g
Number of moles of Cu₂O reacted - 73.5 g / 143 g/mol = 0.51 mol
According to the molar ratio,
when 1 mol of Cu₂O reacts then 2 mol of CuCl is formed
therefore when 0.51 mol of Cu₂O reacts then - 2 x 0.51 mol of CuCl is formed
number of CuCl moles formed - 1.02 mol
mass of CuCl formed - 1.02 mol x 99 g/mol = 101 g
mass of CuCl formed is 101 g
Answer:
Explanation:
The solution of known concentration is expressed as molarity. Molarity is the mole fraction of solute (i.e. the dissolved substance) per liter of the solution, Molarity is also commonly called molar concentration.
Mathematically;
To copy and complete the road map from the given question, we have the following array:
Volume A (L)
↓
d. multiplied by the molarity of A
↓
moles A
↓
b. multiplied by the moles of B / moles of A
↓
moles B
↓
c. divided by the molarity of B
↓
volume B (L)
