Answer:
H₂Lv
Explanation:
Lv is at group 6 on the periodic table, so it has 6 valence electrons, likely oxygen. Thus, to be stable, it needs to gain 2 electrons. Hydrogen has 1 electron in its valence shell, so H₂ can share 2 electrons with Lv, and because of that, the product would be:
H₂Lv.
V = 38.55 mL - 15.75 mL = 22.80 mL = 22.80 cm³
D =
=
= 1.392 g/cm³
Answer:
So, electrolysis of water produces 2 volumes of hydrogen gas and 1 volume of oxygen gas because the ratio of hydrogen and oxygen elements in water is 2:1 by volume. Therefore, the amount of gases collected in two test tubes is not equal.
i hope this helped, have a great day
