Answer:
0.745 and 0.245
Explanation:
Mole fraction (χ) is the number of moles of a component divided by the total number of moles in a mixture.
We must calculate the moles of each component.
Let CO₂ be Gas 1 and SO₂ be Gas 2.
1. Calculate the moles of each gas.
2. Calculate the total moles.
3. Calculate the mole fraction of each component
Answer:
alpha decay, because alpha particles have two protons and two neutrons. If the isotope has an atomic number two less than the original, it lost two protons, the same amount as in an alpha particle.

I believe the compound KOI is meant to be potassium iodate, which is KIO₃. This compound will also be the one with the highest melting point.
This is due to the fact that potassium ion will form ionic bonds with whatever atom or molecule it binds to. Ionic bonds involve the complete transfer of electrons, making them very strong and hard to break, meaning the compound will have the highest melting point.
The magnetic field of an electromagnet disappears as soon as current is turned off.
