Hey mate

Explanation:

Let the metal be M

Let the metal be MEquation:

Let the metal be MEquation:MCO3(s) → MO(s) + CO2(g)

Let the metal be MEquation:MCO3(s) → MO(s) + CO2(g)1mol MCO3 produces 1 mol MO and 1 mol CO2

Let the metal be MEquation:MCO3(s) → MO(s) + CO2(g)1mol MCO3 produces 1 mol MO and 1 mol CO2Mass of MO = 280g

Let the metal be MEquation:MCO3(s) → MO(s) + CO2(g)1mol MCO3 produces 1 mol MO and 1 mol CO2Mass of MO = 280gMass of CO2 produced = 500-280 = 220g

Let the metal be MEquation:MCO3(s) → MO(s) + CO2(g)1mol MCO3 produces 1 mol MO and 1 mol CO2Mass of MO = 280gMass of CO2 produced = 500-280 = 220gMolar mass CO2 = 44g/mol

Let the metal be MEquation:MCO3(s) → MO(s) + CO2(g)1mol MCO3 produces 1 mol MO and 1 mol CO2Mass of MO = 280gMass of CO2 produced = 500-280 = 220gMolar mass CO2 = 44g/molmol of CO2 produced = 220/44 = 5 mol CO2

Let the metal be MEquation:MCO3(s) → MO(s) + CO2(g)1mol MCO3 produces 1 mol MO and 1 mol CO2Mass of MO = 280gMass of CO2 produced = 500-280 = 220gMolar mass CO2 = 44g/molmol of CO2 produced = 220/44 = 5 mol CO2Mol of MO produced = 5 mol

Let the metal be MEquation:MCO3(s) → MO(s) + CO2(g)1mol MCO3 produces 1 mol MO and 1 mol CO2Mass of MO = 280gMass of CO2 produced = 500-280 = 220gMolar mass CO2 = 44g/molmol of CO2 produced = 220/44 = 5 mol CO2Mol of MO produced = 5 molmolar mass MO = 280/5 = 56g/mol

Let the metal be MEquation:MCO3(s) → MO(s) + CO2(g)1mol MCO3 produces 1 mol MO and 1 mol CO2Mass of MO = 280gMass of CO2 produced = 500-280 = 220gMolar mass CO2 = 44g/molmol of CO2 produced = 220/44 = 5 mol CO2Mol of MO produced = 5 molmolar mass MO = 280/5 = 56g/molMolar mass M = 56 - 16 = 40g/mol

Let the metal be MEquation:MCO3(s) → MO(s) + CO2(g)1mol MCO3 produces 1 mol MO and 1 mol CO2Mass of MO = 280gMass of CO2 produced = 500-280 = 220gMolar mass CO2 = 44g/molmol of CO2 produced = 220/44 = 5 mol CO2Mol of MO produced = 5 molmolar mass MO = 280/5 = 56g/molMolar mass M = 56 - 16 = 40g/molMetal is Ca with molar mass 40g/mol.

Hope it helps ❣️
