Answer:
If the pKa of the acid is low (negative), then the acid is strong.
Explanation:
Ka, <em>the acid ionization constant, </em>measures the strength of an acid in a solution. Stronger acids have higher Ka values.
We defined: pKa = -log[Ka]
This function is a decreasing function, meaning that pKa will be getting smaller and smaller, while increasing Ka (high values of Ka will have negative pKa values). Therefore, stronger acids (high values of Ka), will have low (negative) pKa values.
Solid particles are all compacted together, liquid particles are not as close as solid particles but still move together, and gas particles do not stay together
Boron’s chemistry is not typical of its group. is group 3A (13) shows the increasing metallic character from Al to Tl.
All Boron compounds are covalent whereas the other elements in group 3A (13) form mostly ionic compounds.
Except for Boron, the other elements of group 3A (13) show increasing metallic character from Al to Tl. But Boron is a metalloid.
Compared to the other elements in group 3A, boron has a lower reactivity in chemical terms (13)
The metalloid boron (B), as well as the metals aluminium (Al), gallium (Ga), indium (In), and thallium, are all part of group 3A (or IIIA) of the periodic table (Tl). In contrast to the other members of Group 3A, the element borax primarily forms covalent connections.

It's because the Law of Conservation of Mass WILL NOT be followed if,
from SO2 and water, sulfuric acid is formed. Making a balanced chemical
reaction is not possible, no matter what you do. To obtain or make sulfuric acid, SO2
still needs to be oxidized further to SO3.
