The formula for acceleration if rearranged based on the force equation is- force over mass. So 5000/1200=4.16
Your answer is 4 m/s squared.
This is an amide on the aromatic ring.
HCl + NaOH ---> NaCl + H20
If you follow guidance from other questions I have already answered for you, you will see that the above equation is balanced as it is.
Density = mass/volume
mass of metal =30.2 gram
volume of metal = 22.9-20 = 2.9mL
density = 30.2/2.9 =10.414 gram/mL
