Answer:
HgO (empirical formula)
Explanation:
4.08 - 3.78 = 0.3g (oxygen)
0.02 : 0.02
0.02/0.02 : 0.02/0.02
1 : 1 (ratio)
HgO ( empirical formula)
2HgO ----> 2Hg + O2 ( your equation correct)
I think that the correct answer is D- gets half from each parent
It is reacting as a chemical reaction .
Answer:
d = Hydrogen and oxygen are being formed.
Explanation:
When current is passed through the water electrolysis take place.
Water is splitted into hydrogen and oxygen gas. Because of this formation bubbles are formed.
At cathode:
2H₂O + 2e⁻ → H₂ + 2OH⁻
Cathode is negatively charged and reduction take place on it.
At anode:
4OH⁻ → O₂ + 2H₂O + 4e⁻
Anode is positively charged and oxidation take place on it.
The over all reaction can be written as:
Chemical equation:
2H₂O (electricity) → 2H₂ + O₂
Answer:
1.52 g/mL
Explanation:
The formula for finding the density of an object is d = m/v, or density = mass divided by volume.
Therefore, we can input the two values and solve for d.
d = 220/145
d = 44/29
d ≈ 1.52 g/mL
