- The student uses 3g of sodium hydrogen carbonate and 25cm^3 of citric acid.They record the initial tem perature as 25^circ C and the fina II temp erature as 18^circ C Calculate the energ y taken in from the C surr oundings using the equation below. Energy chonge (I)=Volume of solution (cm^3)times 4.2times Change in temperature (^circ C) 1 Change in tem perature The change in tem perature is tem perature - initial tem perature Change in temperature=^circ C- {}^circ C Change in temperature=^circ C
- as. Liquid A has a density of 1.8g/cm^3 Liquid B has a density of 1.2g/cm^3 80cm^3 of liquid A is mixed with 40cm^3 of liquid B to make 120cm^3 of liquid C. Work out the density of liquid C.
