what is the chemical reaction and mole ratio between oxalate and permanganate in the titration reaction
Tom [10]

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.

Balance the following H2 SO4 + NaOH ==== NaSO + H2O​
katrin [286]

Answer:

H2SO4 + 2NaOH --->   Na2SO4 + 2H2O

Explanation:

H2SO4 + NaOH --->   Na2SO4 + H2O

                Na1    --->     2Na

H2SO4 + 2NaOH --->   Na2SO4 + H2O

2H   +   2H =  4H       ---->                 2H

H2SO4 + 2NaOH --->   Na2SO4 + 2H2O

     4O  + 2O         ----->          4O   +     2O

A chemist has a 3.25-mole sample of potassium (K) to use in an experiment. What is the mass of this sample?
s344n2d4d5 [400]
Hi!
• For this you want to convert moles to grams
• To do this you would simply multiple your moles times the atomic mass of potassium
3.25 x 39.098= 127.0685
• So your answer for this should be about 127.07 depending on how you need to round!
