a block of aluminium at room temp is 20cm when heated it increases to 25cm when back to room tempthe volume returns to20cm why does this happen

Calculate the theoretical yield of NaCl (using mass-to-mass calculation). (Use the mass of sodium carbonate reactant used as the starting point, along with the relevant mole ratio from the balanced equation to perform this calculation). Work must be shown...

setting it up

the mass of the sodium carbonate is 0.575g, while the mass of the sodium chloride is 0.577g

thank you so much!
