Answer:
126.73 mL
Explanation:
The total pressure of the gas mixture is the sum of the vapor pressure of its constituents. So, the vapor pressure of N₂O(p) can be calculated:
750 = 18.85 + p
p = 750 - 18.85
p = 731.15 torr
It means that for 731.15 torr, N₂O occupied 130 mL. For the general gas equation, we know that
Where <em>p</em> is the pressure, <em>V</em> is the volume, <em>T</em> is the temperature, 1 is the initial state, and 2 the final state. For the same temperatue (21ºC), the equation results on Boyle's law:
p1V1 = p2V2, so:
731.15x130 = 750xV2
750V2 = 95049.5
V2 = 126.73 mL

Nitric acid does NOT react with water, water disassociates the molecules into those ions (above). ... Water,Being a polar solvent,…makes HNO3 ionise or dissociate or simply break down into Hydronium ions, i.e,H+ or H3O+ ions and nitrate NO3- ions..that's all.

Explanation:
Helium is produced in radioactive process that occurs in deep and underground formations. They differ from other atmospheric gases. These radioactive decay of heavier nuclides that are unstable started about the time when the earth was formed.
- As they decay they give off lighter particles that can easily be broken down into more stable ones.
- One of the main product of the decay is alpha particles.
- They have the same atomic structure as helium
- These materials are trapped in underground formations.
