Answer:
18.0 g of mercury (11) oxide decomposes to produce 9.0 grams of mercury
Explanation:
Mercury oxide has molar mass of 216.6 g/ mol. It gas a molecular formula of HgO.
The decomposition of mercury oxide is given by the chemical equation below:
2HgO ----> 2Hg + O₂
2 moles of HgO decomposes to produce 1 mole of Hg
2 moles of HgO has a mass of 433.2 g
433.2 g of HgO produces 216.6 g of Hg
18.0 of HgO will produce 18 × 216.6/433.2 g of Hg = 9.0 g of Hg
Therefore, 18.0 g of mercury (11) oxide decomposes to produce 9.0 grams of mercury
Most <span>scientists </span>suggest diminishing carbon dioxide outflows. Less carbon dioxide in the climate would be relied upon to diminish the quantity of biotic calculates biological systems. A biotic element is any living part that influences the number of inhabitants in another living being, or the earth. This incorporates creatures that expend the life form and the living nourishment that the living being devours.
