Hello!
In this case, since the ionization of ammonia, which is a weak base, is written as:
We can see that the ammonium ion is the conjugate acid whereas the hydroxide ions the conjugate base; that is why we use the Henderson-Hasselbach equation to compute the pH, given the pKb of ammonia 4.75:
![pH=pKb+log(\frac{[conj\ acid]}{[base]} )](https://tex.z-dn.net/?f=pH%3DpKb%2Blog%28%5Cfrac%7B%5Bconj%5C%20acid%5D%7D%7B%5Bbase%5D%7D%20%29)
In such a way, for the given moles of ammonia, base, and those of ammonium chloride, conjugate acid form, we obtain:
Best regards!
Answer:
They have properties of both metals and nonmetals
Explanation:
- Elements in the periodic table may be divided into Metals, non-metals, and metalloids.
- Metals are the elements that react by losing electrons to form stable positively charged ions known as cations. Examples are group 1, 2, and 3 elements together with transition elements.
- Non-metals are those elements that react by gaining electrons to form stable negatively charged ions called anions. Examples include oxygen, carbon, sulfur, etc.
- Metalloids, on the other hand, are elements that have both metallic and non-metallic properties.
- Metalloids occur between metals and non-metals in the periodic table. Examples include Boron and silicon among others.
