1. two types of reaction occur when baking soda and vinegar combine. the first is a double replacement reaction. write a balanced equation for this reaction. balance both equations. (hco3) + h(c2h3o2) → (c2h3o2) + → + 2. what type do you think the second reaction is? why?

1NaHCO3 + 1HC2H3O2 → 1Na(C2H3O2) + 1H2CO3
First reaction is balanced, there is no need to write coefficient 1 in front of molecule.
1H2CO3 → 1H2O + 1CO2
Second reaction is also balanced. This type of reaction is calling chemical decomposition or analysis, because one molecule separats into its two simpler compounds.

That result from subduction of oceanic plates beneath lighter continental plates. most of the earth's volcanoes are located around the pacific ring of fire because that the location of most of the earth's subduction zones.
