A friend shows you a bar graph made from data collected on endangered species. It's not good. Identify problems with this graph and suggest improvements.
i attached the picture of the question btw :) pls help

Ibeg i need 20. a reaction produces 4.93 l of oxygen, but was supposed to produce 1 mol of oxygen. what is the percent yield?

If 1.8 l of water is added to 2.5l of a 7.0 m koh solution, what is the molarity of the new solution

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?
