> 2na + cl2
which types of chemical reactions are represented by these equations?
(1) single replacement and decomposition(2) single replacement and double replacement(3) synthesis and decomposition(4) synthesis and double replacement

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
