Complete and balance these equation (if necessary):

(i) naoh(aq) + nh4cl(s) =

(ii) oh-(aq) + nh4+(aq) =

In this case, the NH4Cl is specified as a solid.

Its important to note that, as Im not convinced it can be written other than

Na+ (aq) + OH-(aq) NH4Cl(s) > NaCl(s) + NH3(g) + H2O(l)

which would serve as your ionic/net equation.

your molecular would be

NaOH(aq) + NH4Cl(s) ---> NaCl(s) + NH3(g) + H2O(l)

am curious what the higher ups have to say regarding this one! ;-)

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
