Answer: Ok I think The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Carbon, or 12.0107 grams. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between moles Carbon and gram. 12 grams
This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.
hope this helps have a awesome night/day❤️✨

The <u>concentration of hydronium ions</u> and the pH value is related by the equation: <u> pH=-Log[H+]</u>
Explanation:
We have two different concepts pH and concentration of <u>hydronium ions</u>. Lets start with the hydronium ion.
An hydronium ion is a species that is produced by an <u>acid</u>:
Aditionally, we can have the production of <u>hydroxide ions</u>. The subtances that have the capacity to produce this ions are called <u>"bases"</u>:
Now we can continue "pH"
The <u>pH is a scale</u> that indicates if the substance is and <u>acid</u> (higher concentration of 
), <u>neutral</u> (equal amounts of 
and 
) or <u>basic</u> (higher amount of ).
Finally, the "pH" is calculated with the concentration of the hydronium ions (
), the letter <u>"p" is "-Log"</u>, therefore:
![pH=-Log[H^+] ](https://tex.z-dn.net/?f=pH%3D-Log%5BH%5E%2B%5D%0A)

Answer: 0.45 mole Fe
Explanation: solution
25 g Fe x 1 mole Fe / 56 g Fe
= 0.45 mole Fe
Cancel out grams of Fe.
Answer:
Radioactive decay is the process in which the nucleus of an unstable isotope spontaneously changes, releasing particles and energy. An unstable isotope will continue to decay until it reaches the stable form of either a different isotope of the same element that is stable or a different element that is stable.
