250J of heat was added to a 2 g block of metal. The temperature of the metal was increased by 139.4K. What is the specific heat capacity of the metal? Use the below equation to calculate specific heat capacity.

Include three decimal places and do not use units in your answer.

cmetal = Q/mΔT

Reacting masses1 calcium carbonate breaks down on heating to produce calcium oxide and carbondioxide gas.caco3 + cao + co2a student heats 15 g of calcium carbonate strongly in a crucible.relative atomic masses (a): ca = 40, c = 12, o = 16.calculate the mass of calcium oxide produced by this reaction.(5 marks)
