Answer:
its stored in the covalent bonds
<u>Answer:</u> The volume of oxygen gas is 
<u>Explanation:</u>
To calculate the volume of the gas, we use the equation given by ideal gas equation:

where,
P = pressure of the gas = 5 MPa = 5000 kPa (Conversion factor: 1 MPa = 1000 kPa)
V = Volume of gas = 3.34 L
n = number of moles of oxygen gas = 1 mole
R = Gas constant = 
T = Temperature of the gas = 200 K
Putting values in above equation, we get:

Hence, the volume of oxygen gas is 
Atoms are not created or destroyed by chemical reactions. Also, matter is neither created nor destroyed, it just changes form. ... The Law of Conservation of Mass states that in a chemical reaction the total mass of reactants is equal to the total mass of products.
The square of the planet's orbital period is proportional to the cube of its semimajor axis.
89 - 39 = 50
The atom has 50 neutrons. Hope this helps! :)
