Answer: The basicity of the salt anion
Explanation:
All the weak acid is neutralized at the equivalence point and transferred to its conjugate base (number of moles of H+ = increased number of moles of OH–). Therefore the solution produced is weakly alkaline and the pH of the equivalence point will be greater than 7.
Pressure caused by high temperatures are balanced by gravity
Answer:
[(x-37.5)/x]*100%
62.5% (assuming the original sample weighs 100.0g)
Explanation:
Let's say that the original sample is x
Mass of I-125 which has decayed: x-37.5
Percentage of decayed mass: [(x-37.5)/x]*100%
Please recheck, for this may not be the correct answer

Answer:
Reducing agent: nitrogen.
Oxidizing agent: chromium.
Explanation:
Hello,
In this case, the first step is to rewrite the undergoing chemical reaction indicating the oxidation state for each atom as shown below:
In such a way, we observe the following half-reactions:
* Reduction as chromium undergoes a decrease in its oxidation state:
* Oxidation as nitrogen undergoes an increase in its oxidation state:
In such a way, we state that the nitrogen is the reducing agent as it is oxidized and chromium the oxidizing agent as it is reduced, therefore, the balanced chemical reaction turns out:
Best regards.
