The structures and chemistry of individual hydrocarbons depend a large part on the types of chemical bonds that link together the atoms of their constituent molecules. Hydrocarbons are derived by chemical degradation.
Answer:
5000 molecules of A will needed to react with 5000 molecules of B to gives 5000 molecules of AB.
Explanation:
A+B → AB
Given that 100 molecules of A combines with 100 molecules of B to give 100 molecules of AB.
According to reaction, 1 molecule of AB is produced by 1 molecule of A.
Then 5000 molecules of AB will be given by:
molecules of A
5000 molecules of A will needed to react with 5000 molecules of B to gives 5000 molecules of AB.
It gives each organelle in the cell its own specific function
The pH can be determined by the base dissociation constant value (Kb). The pH of the solution after 15 mL of ammonia is added to the solution will be 10.26.
<h3>What is pH?</h3>
The pH of the solution can be given by the pOH value that is determined by the concentration and the base dissociation constant.
The balanced chemical reaction is given as,
HCl + NH₃ → NH₄Cl
The moles before reaction was 0.015L× 0.15M = 0.00225 moles and, 0.025 L × 1.00 M = 0.025 moles
The moles after reaction are 0.00225 moles - 0.025 moles = 0.02275 moles
pOH is calculated as,
pOH = 4.74 + log ( 0.00225 ÷ 0.02275 )
= 3.73
Further pH is calculated as,
pH = 14 - 3.73
= 10.26
Therefore, 10.26 is the pH of the solution.
