When electricity flows through water, the water molecules split into molecules of hydrogen and oxygen gas. How many oxygen (O2)
2 answers:
Answer: The number of oxygen molecules produced are 1.
<u>Explanation:</u>
Water is formed by the combination of hydrogen and oxygen atoms.
Water splits into 2 types of molecules when electricity is applied.
The balanced chemical equation for the splitting of water into its molecules follows:
By Stoichiometry of the reaction:
2 moles of water splits to form 2 moles of hydrogen molecule and 1 mole of oxygen molecule.
Or,
2 molecules of water splits to form 2 molecules of hydrogen and 1 molecule of oxygen.
Hence, the number of oxygen molecules produced are 1.

Answer:
Final temperature of the gas is 576 .
Explanation:
As the amount of gas and pressure of the gas remains constant therefore in accordance with Charles's law:
where and
are volume of gas at
and
temperature (in kelvin scale) respectively.
Here ,
and
So
849 K = (849-273) = 576
So final temperature of the gas is 576 .
Answer:
0.962 atm.
97.4 kPa.
731 torr.
14.1 psi.
97,434.6 Pa.
Explanation:
Hello.
In this case, given the available factors equaling 1 atm of pressure, each required pressure turns out:
- Atmospheres: 1 atm = 760 mmHg:
- Kilopascals:: 101.3 kPa = 760 mmHg:
- Torrs: 760 torr = 760 mmHg:
- Pounds per square inch: 14.69 psi = 760 mmHg:
- Pascals: 101300 Pa = 760 mmHg:
