An environmentalist uses a bar graph, a diagram, and a map as part of a presentation to Congress about global warming. Based on the process outlined in the diagram, what has most likely caused the higher levels of global surface temperature since the 1980s, as shown in the bar chart?

screening

explanation:

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
