**CHEMISTRY**

You subtract the moles of NaoH from the moles of HCl to determine the excess moles left, which decides the pH. To find pH, pH= -log(concent. of H+) or ( concen. of OH-) If NaOH is more than HCl, you get find pH by subtracting the pOH you get from the above formula from 14.

**physics**

Devon : a = F / m Effective F = upward force - downward force (weight) = 11- 15.5 = 4.5 downward a = 4.5/ (15.5/9.8) = 2.8 m/s downwards. (I'm pretty sure anyway)

**physics**

Yes if the upward force is less than gravitythen the acceleration would be downward, but it wouldn't be negative as it's not a deacceleration. :)

**Chemistry**

Balance the eqn Na2CO3 + 2HCl -> 2NaCl +H20 + CO2 From the balanced eqn you can see that one mole of CO2 is produced. Then at stp 1 mole of gas takes up 24 litres (I think, check this on google) therefore v= 24 litres. :)
