NH₄Cl → NH₄⁺ + Cl⁻
NH₄⁺ (the ammonium cation)
Answer:
6
Explanation:
im guessing because there is no diagram
Answer:
1st one is...
Explanation:
The 1st one is change in size or shape. 2nd one is formation of precipitate. 3rd one is physical change. 4th one is formation of gas.
<span>the chemistry of carbon compounds (other than simple salts such as carbonates, oxides, and carbides).</span>
Assuming that the reaction is unimolecular on both
reactant and product sides such that:
HA + OH-
--> A- + H2O
Therefore the amount of A- left is:
mmol HA = 9.00 - 3.00 = 6.00 <span>
mmol A- = 3.00
pKa = - log Ka = 5.25
</span>
<span>Calculating for pH:
pH = 5.25 + log 3.00/6.00</span>
<span>
pH = 4.95 </span>
