Plz try to help me if u can?

Zn(NO3)2(aq) + 2NaOH(aq)  —> Zn(OH)2 (s) + 2NaNO3(aq)

Zn++ + 2NO3-  + 2Na+ + 2OH- —> Zn(OH)2 + 2Na+ + 2NO3-

Zn++ 2OH- —> Zn(OH)2

Na+, NO3-

Explanation:

Zn(NO3)2(aq) + 2NaOH(aq)  —> Zn(OH)2 (s) + 2NaNO3(aq)

B. bar

Explanation: Pressure is defined as the force exerted per unit area.

S.I. unit of force is Newton(N)  

S.I. unit of length= meter(m)

Thus units of pressure can be or atmosphere or bar or Pascal.

A. : This is the unit of Volume. Volume=

C. : This is the units for=

D. Celsius: This is the unit of temperature.
