How to Balance Redox Equations? Cu + HNO3 -> Cu(NO3)2 +N2O + H2O

I can usually follow along when my professor does these, but I'm confused how to start them on my own when they have compounds instead of just elements.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

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

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
