If you change the subscripts it would change the reactants or products and then you would be solving a different formula, you would change what the chemical is
Answer: i don't know
Explanation:

If the ion is negatively charged, anion, it means that it gains two
electrons from its surroundings. The number of electrons of an argon (neutral
atom) is 18. Two of the electrons in our anion is from the surrounding, so
originally it only has 16 electrons.
In the periodic table, the 16th element is sulphur. The
chemical symbol of sulphur is S. Thus, the anion is the negatively charged
sulphur with chemical symbol of S2-.
Answer: $$3.60 * 10^(21)$$
Explanation: Let's try to create a conversion factor that will take us directly from the number of grams of calcium oxide
Answer: 126.1 grams of are needed to make 5.3 L of 0.25 M solution
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
To calculate the mass of solute for given molarity, we use the equation:
Thus 126.1 grams of are needed to make 5.3 L of 0.25 M solution
