Decide whether each chemical reaction in the table below is an oxidation-reduction ("redox") reaction. If the reaction is a redox reaction, write down the formula of the reducing agent and the formula of the oxidizing agent. redox reaction? yes no HNO3(aq) + H20(l) = H30 (aq) + NO3(aq) reducing agent: ? oxidizing agent: redox reaction? yes O no C(s) + 02(g) = CO2(g) reducing agent: oxidizing agent: redox reaction? O yes no FeO (s) + CO(g) → Fe(s) + Co3 (g) reducing agent: 6 oxidizing agent:​

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
