A forest is made up of Hickory and Oak trees. The forest has changed very little in the last 100 years. What level of ecological succession has been reached?

How many grams of n2h4 will be consumed by 23 g of n2o4

What natural processes produce large quantities of co2

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
