What mass of zinc oxide would be produced by the thermal decomposition of 375 grams of zinc carbonate?
Llana [10]
Zinc carbonate has the chemical formula : ZnCO3 and the equation for thermal decomposition is:
ZnCO3 .................> ZnO + CO2
1 mole of ZnCO3 produces one mole of ZnO

From the periodic table:
molar mass of zinc = 65.38 gm
molar mass of carbon = 12 gm
molar mass of oxygen = 16 gm

molar mass of ZnCO3 = 65.38 + 12 + 3(16) = 125.38 gm
molar mass of ZnO = 65.38 + 16 = 81.38 gm

125.38 gm of ZnCO3 produces 81.38 gm of ZnO, therefore:
mass of ZnO in 375 gm = (375 x 81.38) / 125.38 = 243.4 gm

Based on the above calculations, the correct answer is 243 grams

Which Scientists’ observations eventually led to the theory of continental drift?
Vitek1552 [10]

Alfred Wegener

Explanation:

Alfred Wegener in 1912, proposed the theory of continental drift from his careful studies of different land masses. From his observations, he suggested the following:

  • Some fossils of tropical plants were found in polar and temperate regions.
  • Fossils of mesosaurus were found in South America and South Africa now separated by the Atlantic ocean.
  • He fitted the continents into a giant land mass puzzles.
  • Coal beds in Europe were similar to those in United States.
  • Mountain chains in the edge of West Africa was similar to that of Eastern part of South America.

His theory lacked a mechanism which facilitated the plate movement.
