A solution of toilet bowl cleaner has PH of 13 the solution is?
AlladinOne [14]
The solution is an alkali.

Usually with the pH value range of 14, substances with pH 7 can be called neutral. Meanwhile substances lower than pH 7 are acids, the lower the pH is, the more acidic it is. Such as cola, it has a pH 2, which is very acidic.
In opposite, the substances with pH over 7 are called alkalis. Again, the larger the pH value is, the more alkaline it is. So pH 13 is a strong alkaline therefore it it corrosive and can clean the toilet well.

Part A What are plate boundaries at which lithospheric plates that a) move toward each other, b) move past each other, and c) mo
Alex787 [66]

Answer:

a. Convergent boundary

b. Transform boundary

c. Divergent boundary

Explanation:

Convergent boundary are boundary where tectonic plates collide with each other. This kind of boundary might involve a collision between continental and oceanic plates, continental and continental plates and oceanic and oceanic plates. Generally, convergent boundary are regions for mountainous structures . Example of mountain formed through convergence are mountain Everest and Himalayas .

Transform boundary are boundary where tectonic plates move past each other . This kind of boundary is responsible for the creation of Extensive Fault like the San Andrea Fault.

Divergent boundary are boundary where tectonic plates move away from each other.  The diverging movements brings about oceanic ridges. The mid oceanic ridges is where magma rises to the surface to form a new crust. The up welling of this magma causes further separation of this plates.

The picture above illustrate convergent, divergent and transform boundary.
