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?

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

la respuesta es si te gusta hacer lo que siempre haces cuando nunca ves a alguien en el espejo porque sabes que no siempre están ahí.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
