Using the following reactions: 2KMnO4 + 5KNO2 + 3H2SO4 > 2MnS4 + #H2O + 5KNO3 + K2SO4
KClO3 + C12 H22O11 ---> KCl + H2o + CO2
K2Cr2O7 + SnCl2 + HCl ---> CrCl3 + SnCl4 + KCl + H2O
Mg + HCl > Mg Cl2 + H2
Fe + V2O3 ---> Fe2O3 + VO
How many of the above reactions are oxidation -reduction reactions?

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i  

that's what i got you can count the number of atoms

it takes on an electronical energy

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
