Answer:

Explanation:
Hello,
In this case, we can apply the Boyle's law in order to understand the pressure-volume relationship as an inversely proportional relationship relating the initial and the final volume:

Next, we compute the final pressure P2:

Thus we validate, the higher the volume the lower the pressure.
Best regards.
Answer:
I
Explanation:
Among the halogens given in this problem, iodine has the lowest attraction for electrons.
This property is known as electronegativity.
Electronegativity is expressed as the relative tendency with which the atoms of the element attracts valence electrons in a chemical bond.
- As you go down the periodic group the electronegativity decreases.
- The most electronegative element on the periodic table is fluorine.
- Down the group, iodine is the least electronegative
- This is due to the large size of its atom.
Answer:
1.38 x
atoms
Explanation:
To get grams to atoms/molecules/particles we need to first convert grams > moles > atoms. This also applies in the other direction, where you have moles as that stepping stone.
Some key information we need:
Magnesium's molar mass= 24g/mol
Avogadro's Number= 6.022 x
atoms
Where there is 1 mol per 6.022 x
atoms
*This maybe be something you want to memorize.
Grams to moles using molar mass , then to atoms using avogadro's number.
55g Mg x
x
= 1.38 x
atoms
