Which formula equation shows a reversible reaction? a. 2na+f2–> 2naf b. caco3–> cao+co2 c. nh4ci(s)—–nh3( g.+hci( g. 2h2o2(aq)–pt—> 2h2o(i)+o2( g.?

The formula equation that  shows   a  reversible  reaction  is

NH4Cl (s) ⇔ NH3 (g)  + HCl (g) ( answer  C)

            Explanation

Its c I just took the test

you should just be yourself and not let any body tell you other wise.

explanation:

why?

because if they don't love you for your self then they don't deserve you.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
