Wednes-Day 1
Bio- we discussed various ways that humans can negatively impact ecosystems. From deforestation, which reduces the producer/autotroph level of organisms and can cause ecosystem instability, to monoculture farming, the planting of a single type of crop that can deplete the nutrient-rich layer of topsoil of the same essential nutrients so that the soil becomes less and less fertile for plants, we gave several examples of some of the negative effects that humans can and do cause.
Chem 7- we learned how to spot redox reaction by quickly inspecting whether a reaction is a single replacement or synthesis (from elements). We saw that double replacement reactions are NOT redox reactions and that decompositions may or may not be redox reactions.
We also balanced some complex redox reactions via the oxidation number method.
Chem 8/9- we learned how to spot redox reaction by quickly inspecting whether a reaction is a single replacement or synthesis (from elements). We saw that double replacement reactions are NOT redox reactions and that decompositions may or may not be redox reactions.
We also balanced some complex redox reactions via the oxidation number method.
We then finished our acid-base titration lab discussion.
