Based on your question where there is a concentration of 1 M, the weak acid HN02 is 2% ionized nad the PH of the solution is 1.2. The possibilities that could happen to KNO2(s) if it will dissolved into the solution is that w<span>hen more nitrite is added to the solution, the reaction will shift towards the reactants because of La Châtelier's principle. In doing this, the solution will decrease in hydronium concentration and therefore the pH will increase by some amount.</span>
We can solve this problem using the long hand solution, wherein we 1 by 1 analyze the different equilibrium reactions or by simply using the Henderson Hasselbach equation. The equation is
pH = -log(pKa) + log (salt/acid)
since the acid and the salt have the same concentration, the log (salt/acid) term is equal to zero.
thus
pH = -log(1.73*10-5)
pH = 4.76
please be careful with the negative sign
Answer:
gravitational
Explanation:
Potential energy that is related to an object's height above the ground is known as gravitational potential energy.
Potential energy due to the position of an object above Earth’s surface is called gravitational potential energy.
Probably its atomic number (proton number), because this is how they are arranged already.
Other factors are their form (metal/non-metal) etc., which determines how they react with each other and bond.
Another important factor is the number of electrons in their valent (outer) shell. This is because it tells use how the atom will react/bond with other atoms, how 'violent' that reaction will be, and whether it will bond at all (eg. nobel gases)
Answer:
science is nothing without funding
Explanation:
Well Science in the US is highly a political affair. Scientists need funding for research, so they usually have to obtain grants from people who have the means to spare it. In many cases that means people who are involved with the government, or have close ties to it.
So scientists find themselves having to play off partisan politics in order to secure the funding they need for their research. Many times they also find that their research will inevitably get skewn to meet the original funders own ends.
Mostly what I have said is commonly known. However I am in school, and deal with scientists and doctoral researchers who have expressed and validated similar experiences.
