the atomic number is equal to the number of protons an element has.
Solid state of matter
- the atoms are tightly packed in orderly form, they slightly vibrate but are stuck in a fixed position. Solids cannot be compressed and they maintain their shape
Spectator ion are ions which remain unchanged during chemical equation and does not affect equilibrium
chemical equation for the reaction is as follows
NaSO4 +Babr2 ---> 2 Nabr + BaSO4
ionic equation is as follows
Ba ^+2 + SO^-2 --->BaSO4(s)
therefore the spectator ion are Na+ and Br- ions
There is four stages of technological design:1. identify a problem or need.2. design a solution.3. implement, build, test the design.4. determine if the solution met the need.To design a solution is second stage of technological design.
