It is a graph. It shows observations and then you record your results with any of the graph types.
The negative log function that determines the acidity or alkalinity by hydronium ion concentration is called pH.
The substance having high ![\rm [H]](https://tex.z-dn.net/?f=%5Crm%20%5BH%5D)
will have:
Option B. A low ![\rm [OH ^{-}]](https://tex.z-dn.net/?f=%5Crm%20%5BOH%20%5E%7B-%7D%5D)
and a high 
This characteristic can be explained as:
- The concentrations of
![\rm [H^{+}]](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D)
and are inversely dependent on each other so when the concentration of raises then the concentration of drops and vice versa.
- The pH of a solution or substance is calculated with the help of:
![\rm pH = \rm - log \rm [H^{+}]](https://tex.z-dn.net/?f=%5Crm%20%20pH%20%20%3D%20%5Crm%20-%20log%20%20%5Crm%20%5BH%5E%7B%2B%7D%5D)
From the formula, it can be deduced that when the concentration of is high then the pH has a low value and it means that the solution is acidic.
- pH can also be written as:
From this formula we can that when the value of pH is less then the value of pOH will be increased and vice versa.
Therefore, when pOH is in high concentration then is low.

Answer:
<h3>The answer is 2.0 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 4 g
volume = 2 cm³
We have
We have the final answer as
<h3>2.0 g/cm³</h3>
Hope this helps you
Hi!
• For this you want to convert moles to grams
• To do this you would simply multiple your moles times the atomic mass of potassium
3.25 x 39.098= 127.0685
• So your answer for this should be about 127.07 depending on how you need to round!
Answer:
(x+10) (x+3)
Explanation:
1) this quadratic equation is in the form of: ax^2+bx+c
where we need to figure out what*what=c(30)
and what+what=13(b)
factors of 30: -1,-30 1,30 2,15 -2,-15 3,10 -3,-10 5,6 -5,-6
factors of 30 which equal 13: 3,10
lets substitute 3 and 10 in lace of 13x to factor by grouping:
x^2+3x+10x+30
make two sets:
set a) x^2+3x
set b) 10x+30
the GCF in set a is "x":
x(x+3)
The Gcf in set b is 10:
10(x+3)
now combine the terms outside the parantheses:
(x+10)(x+3)=0
Hope this helps!
