Answer:
I think it's 6 moles are produced
Answer:
Chemical
Explanation:
The change was chemical, because it can no longer be returned to the original form. You cannot get back the bubbles or fizz from the air.
Under standard temperature and pressure conditions, it is known that 1 mole of a gas occupies 22.4 liters.
From the periodic table:
molar mass of oxygen = 16 gm
molar mass of hydrogen = 1 gm
Thus, the molar mass of water vapor = 2(1) + 16 = 18 gm
18 gm of water occupies 22.4 liters, therefore:
volume occupied by 32.7 gm = (32.7 x 22.4) / 18 = 40.6933 liters
The trend in ionization energy that occurs across a period on periodic table is that
Ionization energy of elements within a period generally increases from left to the right.
<u><em>explanation</em></u>
Ionization energy is energy required to remove an electron from gaseous atom or ion.
The ionization energy increase across the period because, as you move across the period (from the left to the right) the atomic radius decrease.
This make outer electrons to be closer to the nucleus and more attracted to the center.Therefore it is hard to remove electron as you move across the period.
