to find the slope, it is rise over run, rise/run
y-intercept is where the line crosses the y-axis
slope is positive or negative depending which way it is leaning, if it goes up-to-down from left-to-right that means it is negative, on the other hand, if it goes down-to-up from left-to-right means it is positive
Hope this helps :)
No, because HPO₄ is a multi-atom ion and has its own name which is Hydrogen phosphate.
The correct answer is option B.
Research focused on how to cure cancer is an example of applied research.
The examples of basic research are :
A.) Research focused on how the human brain works
C.) Research focused on detecting life on other planets
D.) Research focused on human behavior
Applied research targets to solve specific human problems that have commercial value in the present day. Basic research is about understanding the fundamentals of science and nature, and it is essential to laying down the foundation of applied research.
The mass of the solute required is 250.25 g.
<h3>What is the mass of the solute?</h3>
We know that the number of moles of the solute can be used to obtain the mass of the solute that is required. We can now try to find the mass of the solute that is required.
Concentration of the solution = 0.350M
Volume of the solution = 6.5 L
Number of moles of the solute = 0.350M * 6.5 L
= 2.275 moles
We now have the mass of the solute as;
2.275 moles * 110 g/mol
= 250.25 g
Th measured mass of the solute that we would have to use is 250.25 g.

A chemist wants to make 6.5 L of a .350M CaCl2 solution. What mass of CaCl2(in g) should the chemist use?
Given:
0.607 mol of the weak acid
0.609 naa
2.00 liters of solution
The solution for finding the ph of a buffer:
[HA] = 0.607 / 2.00 = 0.3035 M
[A-]= 0.609/ 2.00 = 0.3045 M
pKa = 6.25
pH = 6.25 + log 0.3045/ 0.3035 = 6.25 is the ph buffer prepared.
