To completely neutralise 200cm3 of 0.5mol/dm3 sodium hydroxide (NaOH), a student adds 100cm3 of 0.5mol/dm3 sulfuric acid (H2SO4). The temperature of the solution goes up by 4.5°C. The equation for the reaction is

2NaOH(aq) + H2SO4(aq) → Na2SO4(aq) + 2H2O(l)

a. Calculate the amount, in moles, of NaOH in the sodium hydroxide solution.

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.

Heat is the total potential energy of a substance that can be transferred. true false
