I am pretty sure u have pictures and this one should be the one that erika should make
Hi there!
Zinc: Is qualitative
Chlorine: is quantitative
Gallium: is neither

Answer:
catalysts help speed up reactions which implies that they provide a alternative pathway and when there is less activation energy more particles have more energy to react
Transverse can travel through solids(but not liquids and gas) and longitude can travel through any matter.
Answer:
There are
1.479
×
10
−
13
concentration of hydrogen ions
m
o
l
L
.
Explanation:
Because pH is a logarthmic scale, we can use the formula:
[
H
+
]
=
10
-pH
. Where...
=>
[
H
+
]
is the concentration of hydrogen ions in the solution.
=>
p
H
is the pH of the solution.
=> Where
10
is the base of the power - it's a logarithm formula.
We can now just sub in the values and solve for [
H
+
]
.
[
H
+
]
=
10
-pH
=
10
−
(
12.83
)
=
1.479108388
×
10
−
13
We can round (if required) to
1.479
×
10
−
13
.
Thus, there are
1.479
×
10
−
13
concentration of hydrogen ions
m
o
l
L
.
Hope this helps :)
