In antoine lavoisier’s classic experiment, mercuric oxide is heated in a sealed container. the solid red powder is changed into two products: silver liquid mercury and oxygen gas. if lavoisier heated 100 grams of powdered mercuric oxide to produce 93 grams of liquid mercury, how much oxygen would be released?

a). 7 grams
b). 16 grams
c). 32 grams
d). 93 grams

A) 7 grams

Explanation:

The chemical reaction is:

2HgO\rightarrow 2Hg + O2

Amount of HgO heated = 100 g

Molar mass of HgO = 216.59 g/mol

Molar mass of O2 = 32.00 g/mol

Moles of HgO heated =

Based on the reaction stoichiometry:

2 moles of HgO produces 1 mole of O2

Therefore, 0.462 moles of HgO would produce:

=

Molar Mass of O2 = 32 g/mol

Mass of O2 =

yes, water is wet, just as it makes other things wet, it is wet itself, kinda like ice, when ice is in water, the ice makes water cold, and ice is cold, therefore with that example, water is wet

i need mutiple choices
