5C2O4^(2-)(aq) + 2MnO4^-(aq) + 16H+(aq) → 10CO2(g) + 2Mn2+(aq) + 8H2O(l)` is the chemical reaction and mole ratio between oxalate and permanganate in the titration reaction.
A chemical reaction is a procedure that causes one group of chemical components to change chemically into another. Chemical reactions, which can frequently be described by a chemical equation, traditionally include changes that only affect the locations of electrons in the formation and dissolution of chemical bonds between atoms, with no change to the nuclei (no change to the elements present). The study of chemical processes involving unstable and radioactive elements, where both electronic and nuclear changes may take place, is known as nuclear chemistry.

0.1 moles of chloride ions were involved in the reaction if 25.0 mL of a 2.00 M CaCl2 solution is used for the reaction.
Explanation:
Data given:
volume of Ca
= 25 ml 0r 0.025
molarity of the calcium chloride solution = 2M
number of chloride ions =?
Balance chemical reaction:
Ca + 2 ⇒
number of moles in 25 ml is calculated as:
molarity = 
number of moles of calcium chloride = molarity x volume
putting the values in the equation:
number of moles = 2 x 0.025
= 0.05 moles of calcium chloride
1 mole of Ca decomposes as 1 calcium ion and 2 chloride ions
so 0.05 moles will have x moles of chloride ion
= 
x= 0.1
0.1 moles of chloride ions will be involved in the reaction.
Answer:
In 5 US liquid gallons, there are 80 cups.
Explanation:
To get from gallons to cups, just multiply the amount of gallons you have by 16.
